Why Do Similar Apps Get Different Amounts of Downloads?

Ever wondered why one fitness app gets millions of downloads whilst a nearly identical competitor struggles to hit five figures? I've been building apps long enough to see this pattern play out again and again—two apps that look the same, do the same thing, target the same users, but their download metrics tell completely different stories. It's a bit mad really, because on the surface they might have the same features, similar pricing, even comparable user reviews. Yet one becomes a household name and the other remains virtually invisible.

The thing is, app download rates aren't just about having a good product anymore. Sure, that matters—but its only part of the equation. What I've learned from working with startups and major brands alike is that success in the app stores depends on dozens of interconnected factors that most developers completely overlook. Your app store visibility might be terrible because of keyword choices you made in five minutes. Your onboarding experience could be losing 80% of users before they even see your core features. Or maybe your timing was just off; you launched into a saturated market without understanding the competitive landscape.

The difference between an app that gets downloaded 100 times and one that gets downloaded 100,000 times often comes down to execution details that have nothing to do with the actual product quality.

Over the years I've seen brilliant apps fail because they ignored acquisition benchmarking and market comparison data, whilst mediocre apps succeeded because they nailed their app store performance through careful optimisation and smart marketing. In this guide, we're going to break down exactly why similar apps get such different download metrics—and more importantly, what you can do about it if your apps performance isn't where it needs to be. No fluff, just practical insights from someone who's been in the trenches building and launching apps across every major category.

App Store Visibility and Ranking Factors

Right, so here's something most people don't realise—the app stores aren't just simple lists where apps sit waiting to be discovered. They're complex systems with algorithms that decide which apps get shown to users and which ones basically disappear into the void. And I mean, its not like Google search where you can game the system with a few keywords and some backlinks; app store algorithms look at dozens of different signals to work out if your app deserves to be seen.

The biggest factor? Downloads and install velocity. If your app suddenly starts getting loads of downloads in a short period of time, the algorithm notices and thinks "okay, something interesting is happening here" and starts showing it to more people. But here's the thing—it's not just about total numbers; its about the rate of change. An app that goes from 10 downloads a day to 100 downloads a day will get a bigger boost than an app consistently getting 500 downloads a day. The algorithms reward momentum, not just size.

Text matching plays a huge role too. When someone searches for "fitness tracker" in the App Store, the algorithm looks at your app name, subtitle, and keyword field to see if you're relevant. This is why you'll see so many apps with ridiculously long names stuffed with keywords—developers are trying to rank for as many search terms as possible. Does it look desperate? Absolutely. Does it work? Well... yeah, sometimes it does.

User engagement metrics matter more than most people think. The stores track how often people open your app after downloading it, how long they spend using it, and whether they delete it within the first few days. An app with 10,000 downloads but terrible retention will rank lower than an app with 5,000 downloads where people actually stick around and use it regularly. Quality beats quantity in the long run.

The Role of User Reviews and Ratings

Right, let's talk about something that genuinely keeps app developers up at—well, something that matters quite a lot to app store performance. Reviews and ratings. They're not just vanity metrics or nice-to-haves anymore;they directly impact your app download rates in ways that might surprise you. The App Store and Google Play algorithms both factor ratings heavily into their ranking systems, which means a highly-rated app will naturally appear more often in search results and category listings. But here's the thing—its not just about the star rating itself.

When users browse apps, they're looking at three key signals: your overall star rating, the number of reviews you've received, and what people are actually saying in those reviews. An app with 4.8 stars and 50,000 reviews will almost always outperform an app with 4.9 stars and 200 reviews. Volume matters. A lot. Users trust apps that lots of other people have validated, even if the rating is slightly lower. And I mean, think about it—would you download an app with barely any reviews? Probably not, because you'd wonder if something was wrong with it or if anyone actually uses it.

The recency of reviews matters too, which many people don't realise. Both app stores weight recent reviews more heavily than old ones, so an app that was brilliant two years ago but hasn't been updated and is getting negative reviews now? That'll hurt your download metrics pretty badly. I've seen apps drop from thousands of daily downloads to hundreds simply because they let their review scores slip over a few months.

What Users Actually Look For

People scan reviews differently than you might think. They're not reading every five-star review carefully;they're jumping straight to the three-star and one-star reviews to see what problems they might encounter. Its a defensive behaviour—users want to know the worst-case scenario before committing to a download. This is why responding to negative reviews is so important for acquisition benchmarking against your competitors. When potential users see developers actively addressing complaints and fixing issues, it builds trust. An unanswered complaint? That screams "this company doesn't care about its users" whether thats true or not.

The content of reviews also provides context that star ratings alone cannot convey. Someone might leave three stars because they love the app but it crashes on their specific device—that's different from three stars because the app is fundamentally flawed. Smart users can tell the difference, and they'll factor that into their download decision. I've actually seen cases where apps with lower ratings performed better simply because the negative reviews highlighted minor issues rather than core problems.

How Reviews Affect App Store Performance

Lets break down exactly how this impacts your market comparison with similar apps. When two apps have identical functionality and similar marketing budgets, the one with better reviews will consistently see higher download metrics. It's that simple. But the relationship isn't linear—going from 3.5 stars to 4.0 stars can double your conversion rate, whilst going from 4.5 to 5.0 might only improve it by 10-15%. There's a sweet spot around 4.3-4.7 stars that signals "this app is really good but honest about its limitations" which users actually find more trustworthy than perfect 5.0 ratings.

Here's what directly impacts your app store performance through reviews:

• Search ranking—apps with higher ratings appear higher in search results for relevant keywords
• Conversion rate—the percentage of people who view your app page and actually download it increases with better ratings
• Feature opportunities—app stores are more likely to feature apps with strong review profiles in curated lists and category highlights
• User acquisition cost—better ratings mean higher organic conversion, which lowers your overall cost per install when you're running paid campaigns
• Retention signals—apps with good reviews tend to have better retention, which the algorithms notice and reward with better visibility

One thing that genuinely frustrates me is when developers treat review management as an afterthought. You've spent months building your app, probably tens of thousands of pounds on development, and then you just...hope people leave good reviews? That's madness. Successful apps have deliberate strategies for generating reviews at the right moments. They prompt users after positive experiences, make it easy to leave feedback, and most importantly, they build apps worthy of five-star reviews in the first place. You can't polish a turd, as they say—no amount of clever review prompting will save a poorly built app.

Ask for reviews at moments of success in your app—right after a user completes a meaningful action or achieves something they wanted to do. Never interrupt them during a frustrating experience or when they're trying to accomplish something important. Timing is everything.

The competitive landscape matters here too. If you're in a category where most apps have 3.5-4.0 star ratings, having 4.5 stars gives you a massive advantage. But if you're in a category where everyone has 4.6+ stars, you need to be at that level just to compete. This is why acquisition benchmarking against direct competitors is so important—you need to know what rating threshold you need to hit to be taken seriously in your specific market.

Google Play and the App Store also use ratings as a quality signal when deciding whether to show your app to new users through their recommendation systems. Apps below certain rating thresholds (usually around 3.5-4.0 stars depending on category) effectively become invisible in algorithmic recommendations, which can account for 30-40% of organic downloads. So yeah, reviews aren't just about convincing individual users—they're about convincing the algorithm that your app deserves to be shown to more people in the first place. And that's what really drives the difference in download rates between similar apps.

Marketing Budget and User Acquisition Strategy

Here's the thing—you can build the most brilliant app in the world, but if nobody knows it exists, you've got a problem. I've seen it happen more times than I'd like to admit; a startup will spend six months and £50,000 building their app, then launch it with a marketing budget of basically nothing. They'll sit there refreshing their download stats every five minutes wondering why they're not seeing thousands of users flooding in. It's a bit mad really.

The reality is that similar apps get wildly different download numbers largely because of how much money gets spent on user acquisition—and more importantly, how smartly that money gets spent. One app might be throwing £10,000 a month at Facebook ads with no real strategy, whilst another spends £2,000 but targets it precisely at the right audience at the right time. Guess which one usually wins?

Where Your Marketing Budget Actually Goes

User acquisition costs vary massively depending on your industry. A fintech app might pay £8-12 per install because those users are worth more over their lifetime, whilst a casual gaming app might only pay £1-2 because the monetisation model is different. But heres what most people don't realise—the cost per install is only part of the story. What really matters is how many of those users stick around.

I always tell clients to think about their marketing budget in three chunks: paid acquisition (ads and sponsored content), organic growth tactics (ASO, content marketing, PR), and retention activities (push notifications, email campaigns, in-app messaging). The apps that get the most downloads aren't necessarily spending the most money; they're distributing their budget across all three areas in a way that makes sense for their specific app and audience.

Common Budget Mistakes That Kill Downloads

The biggest mistake? Spending everything on launch week then going silent. Apps need consistent visibility to maintain momentum—downloads breed more downloads through chart rankings and social proof. Another common error is not testing your messaging before you scale up spending; you might be paying for clicks from people who'll never actually use your app because your ad doesn't accurately represent what the app does.

Actually, one of the most cost-effective strategies I've seen is focusing heavily on your existing users. Getting them to share your app, leave reviews, and talk about it on social media costs very little but can drive significant organic downloads. But most companies ignore this completely and just keep pouring money into cold acquisition. Its honestly a waste.

• Paid social ads (Facebook, Instagram, TikTok) – typically £2-8 per install
• Google App Campaigns – usually £1.50-6 per install with good optimisation
• Influencer partnerships – varies wildly but can be £0.50-3 per install if done right
• App Store Search Ads – £0.80-5 per install depending on keyword competition
• Content marketing and SEO – takes longer but can drive free installs over time
• Referral programmes – cost per install depends on your incentive structure

The apps that succeed understand that user acquisition isn't just about buying installs—its about building a system that brings in the right users, at the right cost, who'll actually stick around and use the app. That's why two similar apps can have completely different download numbers even when they're targeting the same market; one has a proper strategy, the other is just hoping for the best.

Timing and Market Conditions

Here's something that doesn't get talked about enough—launching an app is a bit like opening a shop on the high street; if you open a coffee place right next to three established cafes, you're going to have a harder time than if you'd been the first one there. I've watched apps with nearly identical features get wildly different app download rates simply because one launched six months before the other. Timing really does matter.

Market saturation is real and it affects app store performance more than most founders realise. When fitness apps were relatively new, getting downloads was easier because there were fewer options competing for attention. Now? There are thousands of workout apps, which means your download metrics will naturally be lower even if your app is technically better than the competition that launched years ago.

The best time to launch an app was five years ago. The second best time is when you've properly validated your market and built something users actually need.

But here's the thing—timing isn't just about being first. Its also about understanding what's happening right now in your target market. I've seen apps struggle because they launched during economic downturns when people were cutting discretionary spending, whilst others thrived by addressing problems that became urgent during those same conditions. Market comparison shows that seasonal trends matter too; budgeting apps see higher acquisition in January, productivity apps spike in September.

External factors like new phone releases, OS updates, and even privacy regulation changes can impact how your app performs compared to similar ones. An app that launched before iOS privacy changes had time to build a user base and collect data in ways newer apps simply cannot. This creates an uneven playing field that affects acquisition benchmarking across the board. You can't control market conditions but you can time your launch strategically around them.

App Quality and Technical Performance

Right—this is where the rubber meets the road. You can have the best marketing in the world, but if your app crashes every time someone opens it, they're gone. For good. I've seen so many apps with brilliant concepts fail because the technical execution was rushed or poorly planned. And here's the thing, users these days have zero patience for buggy apps; they'll just delete it and move on to a competitor without a second thought.

App stores actually track technical performance as part of their ranking algorithms. Things like crash rates, loading times, battery consumption, how much storage space you're taking up—it all matters. An app that crashes frequently will get buried in search results no matter how many downloads it has. I mean, Apple and Google want users to have good experiences on their platforms, so they're going to push apps that perform well and demote ones that don't. Makes sense really.

What the App Stores Actually Measure

The platforms are looking at your technical performance constantly. Its not just about whether your app works, but how well it works under different conditions. Here's what they're tracking:

• Crash rates (anything above 1-2% is a red flag)
• App launch time (should be under 3 seconds ideally)
• Network request failures and API response times
• Battery drain during normal usage
• Memory usage and storage footprint
• Frame rate consistency (apps should run at 60fps minimum)

But technical quality isn't just about avoiding crashes—its about creating an app that feels fast and responsive. Users can tell when an app is well-built even if they cant explain why. Smooth animations, instant feedback when they tap buttons, pages that load quickly... these things create trust. A polished app suggests a company that cares about details, whilst a janky one makes people question whether their data is safe or if the whole thing might break at any moment.

Testing is absolutely key here, and I'm talking proper testing across different devices, OS versions, and network conditions. You need to test on old phones with limited RAM and new ones with plenty of power. Test on WiFi and on spotty 4G connections. Because your users aren't all running the latest iPhone on a fast connection, are they?

Onboarding Experience and First Impressions

Right, so you've got someone to download your app—brilliant! But here's where things get tricky; this is where most apps lose the battle. I've watched countless apps with similar features get wildly different download metrics, and honestly? It often comes down to what happens in those first 30 seconds after someone opens the app for the first time.

Users make up their mind incredibly fast. Like, really fast. If your onboarding is confusing or takes too long, they're gone before you've even had a chance to show them what makes your app special. And here's the mad bit—they probably won't come back. They'll just move on to your competitor who did a better job at making them feel welcome. I mean, we've all done it ourselves haven't we? Downloaded an app, opened it, got confused, and just deleted it right there.

The apps that win at this stage understand something important; people don't want to work hard to understand your app. They want to see value immediately. Show them one core feature that solves their problem, not five features that might be useful later. Its about getting them to that "aha moment" as quickly as possible—that point where they suddenly understand why your app is worth keeping.

What Makes Good Onboarding

Good onboarding isn't about showing off everything your app can do. Actually, it's quite the opposite. The best onboarding flows I've built follow a simple pattern; show the minimum needed to get value, make it interactive rather than just slides people swipe through, and let people skip if they want to explore on their own. Some users genuinely prefer to figure things out themselves, and that's fine.

Test your onboarding with real people who've never seen your app before. Watch them use it without helping or explaining anything—you'll learn more in five minutes than hours of internal debate will teach you.

Common Mistakes That Kill First Impressions

I see the same mistakes over and over again. Apps that ask for permissions too early (before showing any value), apps with 10+ onboarding slides, apps that require account creation before letting you see anything useful, and apps that use technical jargon instead of plain language. Each of these things creates friction, and friction means people leave.

Here's what actually works for improving app download rates and keeping people engaged after that first install:

• Show value before asking for anything—let people explore a bit first
• Keep the initial experience to under 60 seconds if possible
• Ask for permissions only when they're needed for a feature someone's trying to use
• Use progress indicators so people know how long onboarding will take
• Make tutorials interactive, not just passive slides to swipe through
• Personalise the experience based on why someone downloaded your app

The data backs this up too—apps with well-designed onboarding see 2-3x better retention rates in the first week. That's not a small difference; that's the difference between an app that grows and one that struggles. And better retention means better app store performance overall, because the algorithms notice when people keep using your app instead of deleting it after one session. It all feeds back into your download metrics and market comparison against competitors.

Think about it from a user's perspective. They've just searched for a solution to their problem, looked at probably 5-10 similar apps, read reviews, and decided to give yours a chance. Don't waste that opportunity with a confusing or lengthy first experience. Every extra step you add is another chance for them to bail out and try a competitors app instead. Keep it simple, keep it fast, and focus on showing value first—everything else can come later once they're actually invested in using your app.

Retention Strategies and Long-Term Engagement

Getting people to download your app is one thing—keeping them coming back is where the real challenge begins. I mean, you can spend thousands on user acquisition, but if everyone deletes your app after a week then what's the point? The apps that consistently get more downloads aren't just the ones with big marketing budgets; they're the ones that keep users engaged long enough to become advocates who tell their friends.

Here's the thing—most apps lose about 70% of their users within the first three days. Its brutal but true. The apps that buck this trend are the ones that have thought carefully about why someone would open their app on day two, day seven, and day thirty. Push notifications are powerful here, but only if they're relevant and timely. Nobody wants spam notifications about random offers they dont care about. But a fitness app reminding you about your workout streak? That works because it ties into something you actually want to achieve.

The best retention strategies I've seen focus on creating habits rather than just features. Look at how Duolingo makes language learning feel like a game with streaks and daily goals, or how meditation apps send gentle reminders at the same time each day. These aren't accidents—they're carefully designed systems that turn your app from something people try once into something that becomes part of their daily routine.

What Actually Keeps Users Coming Back

After building apps across different industries, I've noticed certain patterns that consistently drive long-term engagement:

• Progress tracking that shows users how far they've come (works brilliantly for fitness, learning, and productivity apps)
• Social features that let users connect with friends or compete on leaderboards
• Personalisation that gets better the more someone uses your app
• Regular content updates that give people a reason to check back
• Rewards systems that acknowledge milestones and achievements

But here's what really matters—you need to give people a reason to come back tomorrow, not just today. Apps with strong retention dont rely on one big feature; they create multiple touchpoints that keep users engaged. A shopping app might combine personalised recommendations with order tracking and exclusive deals. Each element gives users a different reason to open the app throughout their week.

Measuring What Matters

The metrics you track tell you everything about whether your retention strategy is working. Day 1, day 7, and day 30 retention rates are the numbers I watch most closely because they tell you if people are actually building habits with your app. An app with 40% day-30 retention is going to get far more organic downloads through word-of-mouth than one with 10% retention, even if they start with the same number of installs. Actually, the lifetime value of a retained user is usually 5-10 times higher than someone who churns after a few days, which completely changes the economics of user acquisition.

The apps that consistently rank higher and get more downloads are often the ones that have figured out their engagement loop—that cycle of triggers, actions, and rewards that brings people back again and again. Work on retention and the downloads will follow because happy, engaged users become your best marketing channel.

App Store Optimisation Basics

Right, let's talk about ASO—which is basically just SEO but for app stores. Here's the thing, you can build the most brilliant app in the world but if people cant find it in the App Store or Google Play, your download metrics are going to be absolutely rubbish. I've seen so many apps with incredible functionality struggle because their developers didn't think about discoverability until after launch. Big mistake.

Your app's title is probably the most important ranking factor for app store performance. It needs to include your main keyword (ideally near the start) whilst still sounding natural and appealing to actual humans. Don't stuff it with keywords like its 2005 though; both Apple and Google will penalise you for that. Your subtitle on iOS and short description on Android? Those matter too. Use them wisely.

Keywords work differently in each store which is a bit annoying honestly. Apple gives you a dedicated keyword field with 100 characters—no spaces needed between words, just commas. Google Play doesn't have this, so you need to weave your keywords naturally into your description. Both approaches require proper acquisition benchmarking against your competitors to see what's actually working in your category.

The difference between an app that gets found and one that doesn't often comes down to whether someone took the time to research what terms people are actually searching for

Your icon, screenshots, and preview video all impact conversion rates once people find you. I mean, you could rank first for every relevant search term but if your visuals look like they were made in Paint, people wont download. Test different screenshot layouts, try various icon designs, and always—always—show your app's value in the first screenshot because most people won't scroll. Market comparison data shows that apps with well-optimised visuals convert 20-30% better than those without, which directly impacts your overall app download rates.

Conclusion

So here's what it comes down to—similar apps get different download numbers because success in the App Store isn't just about having a good product anymore. Its about visibility, timing, user reviews, marketing spend, and dozens of other factors that all work together. Or against each other, depending on how well you've planned things out.

I've seen apps with smaller budgets absolutely crush their competition because they nailed their onboarding experience and got brilliant reviews from day one. And I've watched well-funded projects fail spectacularly because they ignored basic App Store Optimisation or launched at the wrong time. The difference between an app that gets 100 downloads and one that gets 100,000 often comes down to these details—the ones that seem small on their own but compound over time.

What really matters is understanding that every factor we've discussed connects to the others; your app quality affects your reviews, your reviews affect your ranking, your ranking affects your organic downloads, and your organic downloads reduce your user acquisition costs. It's all linked together in ways that aren't always obvious when you're in the middle of building your app.

The good news? You don't need to be perfect at everything from day one. You just need to be intentional about your priorities and honest about where your app stands. Start with the basics—make sure your app works properly, create a decent store listing, and focus on getting those first users to have a genuinely good experience. Everything else builds from there. Actually, thats the approach that works best for most of the successful apps I've built over the years; get the fundamentals right first, then optimise the details as you grow.
