How Do I Find Out if My App Market Is Too Crowded?

Have you ever had that sinking feeling after spending months developing an app, only to realise there are already dozens—maybe hundreds—of similar apps doing exactly what yours does? It's a horrible realisation, and one I've seen far too many founders experience. The thing is, most people wait until its too late to ask the question: is my market already too crowded?

I've been building apps for long enough to know that this question keeps more app founders up than almost anything else. And honestly? It should. Because launching into a saturated market without a clear strategy is like opening a coffee shop on a street that already has five of them—you better have something special to offer or you're wasting your time and money.

But here's where it gets interesting; a crowded market isn't always a bad thing. Sometimes it means you've found a space where people actually want to spend money. The trick is figuring out whether there's genuine room for your app or if you're just adding noise to an already deafening marketplace. Market saturation analysis isn't about counting competitors and giving up if the number is too high—it's about understanding the competitive density and finding where the gaps are.

The most successful apps I've built weren't necessarily in empty markets; they were in crowded markets where we found an underserved audience that everyone else had overlooked.

Throughout this guide we're going to look at how you can properly evaluate whether your app idea has real market opportunity or if you're heading towards disappointment. We'll cover competitor landscape evaluation, niche viability testing, and most importantly—how to make smart decisions with actual data rather than gut feelings. Because in my experience, gut feelings have bankrupted more app businesses than bad code ever has.

Understanding Market Saturation and What It Really Means

Market saturation—its one of those terms that gets thrown around a lot, but what does it actually mean for your app idea? Simply put, a saturated market is one where there are already loads of apps doing similar things to what you're planning. But here's the thing—that doesn't automatically mean your app won't succeed.

I've seen people panic when they discover there are ten apps in their category. Ten! That's nothing, honestly. But I've also seen brilliant ideas flounder in spaces with only three competitors because they didnt understand why those three apps existed or who they served. The number of competitors matters less than you think; what really matters is whether those competitors are actually solving the problem well.

A truly saturated market has a few clear characteristics. First, the leading apps have massive user bases—we're talking millions of active users who are genuinely engaged. Second, these apps are constantly updating and improving, which means they're profitable enough to support ongoing development. Third, and this is a big one, user switching costs are high. People have their data, preferences, and habits built into existing apps, making it hard to convince them to move.

What Market Saturation Looks Like in Practice

• Multiple established apps with similar features competing for the same users
• High marketing costs because competition for attention is fierce
• Users have strong loyalty to existing solutions and see little reason to switch
• New features get copied quickly across all major players in the space
• App store rankings are dominated by the same apps month after month

But—and this is important—saturation in one area often means there are underserved niches within that market. The fitness app category might be crowded, but apps for elderly users doing chair exercises? Not so much. That's what we need to look at properly.

Looking at Your Competitors Without Going Mad

Right, so you've decided to do some competitor research—which is smart, by the way, because I've seen too many people skip this step entirely and wonder why their app launch fell flat. But here's the thing: competitive density research can quickly turn into a rabbit hole where you spend weeks analysing every single app that's even remotely similar to yours. Don't do that. Its honestly a waste of time and it'll just make you question everything.

What you actually need is a focused approach. Start by identifying your top 5-10 direct competitors—these are apps that solve the exact same problem for the exact same audience. Download them. Use them properly for at least a week. Read their reviews, especially the negative ones, because that's where you'll find gaps you can exploit. Look at their App Store descriptions and screenshots to see how they position themselves; what features do they lead with? What benefits are they promising? This kind of market opportunity assessment gives you real insight into what users expect as a baseline. If you want to stay on top of what your competitors are doing long-term, you might want to consider setting up automated competitor monitoring to track their updates and changes over time.

What to Actually Look For

I always tell clients to focus on specific things rather than getting overwhelmed by everything. Check their update frequency—apps that havent been updated in months are vulnerable. Look at their monetisation strategy because that tells you what the market will tolerate. Count their reviews and ratings; an app with 50,000 downloads but only 200 reviews suggests poor engagement, which is useful information. Also pay attention to their feature set but don't just make a list—ask yourself why they included each feature and whether users actually seem to care about it based on the reviews.

Building Your Competitor Matrix

Create a simple spreadsheet for your competitor landscape evaluation. You don't need anything fancy.

This matrix becomes your reference point for positioning decisions later on. But—and this is important—don't let competitor analysis paralyse you. I've worked with clients who spent so long studying the competition that they never actually built their app. Set yourself a deadline; spend two weeks maximum on this research phase, gather what you need, and move on. The goal isnt to copy what everyone else is doing or to find the "perfect" gap in the market. The goal is to understand the playing field well enough to make informed decisions about how you'll differentiate yourself and whether there's genuine room for your approach.

Set a timer for your competitor research sessions. Seriously. Give yourself 30-45 minutes per competitor app and stick to it—you can learn everything you need in that time without falling down the endless scroll of app store listings and feature comparisons.

Testing Demand Before You Build Anything

Right, so you've got this brilliant app idea and you're ready to spend months (and probably thousands of pounds) building it. But here's the thing—you really should test if anyone actually wants what you're planning to make. I know its tempting to just dive in and start building, but testing demand first can save you from making a very expensive mistake.

The simplest way to test demand? Create a landing page that explains what your app does and see if people sign up for updates. You dont need anything fancy here; just a clear explanation of the problem you solve, who its for, and a form to collect email addresses. If you can't get a few hundred people interested enough to hand over their email, that's a pretty strong signal that your market might not be as eager as you thought. This approach to building your email list before launch is one of the most reliable validation methods available.

But don't stop there. Actually talk to potential users. I mean real conversations, not just sending out surveys that people ignore. Ask them about the problem you're solving and—this is key—find out what they currently do to solve it. If they don't have a problem they're trying to solve? Well, you probably don't have a viable app idea. And before anyone says "but Apple created demand for products nobody knew they wanted"...you're not Apple, sorry.

Quick Ways to Test Your App Idea

• Build a simple landing page with a sign-up form and run some targeted ads to see if people convert
• Create a basic prototype or mockup and show it to your target audience for honest feedback
• Join online communities where your potential users hang out and gauge interest in your solution
• Offer pre-orders or early bird pricing to see if people will actually commit with their wallets
• Run a small crowdfunding campaign to validate both interest and willingness to pay

The goal here isnt to prove yourself right; its to find out if you're wrong before you've invested everything into building something nobody wants. Trust me, finding out your ideas got legs before you build it is worth every bit of effort you put into testing it properly.

Finding Your Specific Niche Within a Crowded Space

Right, so you've done your competitor research and the market looks absolutely packed—what now? This is where most people make a crucial mistake; they either give up or they try to compete head-on with established players. Neither approach works particularly well, honestly.

The truth is that even in saturated markets there are gaps. Always. I've seen this time and time again with my own clients—someone comes to me saying "there's already 50 fitness apps" and yeah, there are. But none of them are specifically for new mums recovering from C-sections, or for elderly people with arthritis, or for shift workers who cant stick to regular gym schedules. See what I'm doing here? We're getting specific. Really specific.

Your niche needs to be tight enough that you can dominate it but large enough that its actually worth pursuing. I usually tell people to look for markets where existing apps are trying to be everything to everyone—thats your opening. When an app tries to serve every possible user, it ends up serving no one particularly well. You can swoop in and own that underserved segment. It's worth understanding whether your app idea might be too early for the market, which is different from being too crowded but equally important for timing your entry correctly.

The best niches emerge when you combine two or three specific criteria that existing apps aren't addressing simultaneously

Start by mapping out demographic factors like age, profession, location, income level. Then layer on behavioural factors—when do they need your app? What problem are they trying to solve at that exact moment? What devices do they use? A meditation app for lorry drivers during their breaks is fundamentally different from a meditation app for corporate executives in their offices, even though they're both "meditation apps". The context changes everything, and thats where your opportunity lives. Don't just look at who your competitors are targeting; look at who they're missing entirely.

Calculating if There's Actually Room for Your App

Right, lets get into the maths of this—and I promise it wont be too painful. You need to work out if theres genuine space for your app or if you're just adding noise to an already packed market. I've seen too many clients skip this step and regret it later when they've spent thousands building something nobody downloads.

Start with the total addressable market. How many people actually need what you're building? Not "could use it" or "might like it"—genuinely need it. Then look at how many competing apps exist and estimate their combined user base. If the top three apps in your category already serve 80% of the market and they're doing it well, you've got a problem. But here's the thing—markets aren't static, they grow and shift all the time.

Next, calculate what I call the "opportunity gap". Look at app store reviews for your competitors and count how many complaints appear repeatedly. If hundreds of users are moaning about the same missing feature or poor experience, thats your gap. Multiply the number of active users in competing apps by the percentage of negative reviews about specific issues—that gives you a rough estimate of underserved users.

You also need to think about acquisition costs versus lifetime value. If it costs £8 to acquire a user in your category but the average user only generates £5 in revenue over their lifetime, the maths doesnt work; no matter how clever your app is. I've watched apps with brilliant concepts fail simply because the economics never made sense from the start.

Finally, consider your resources honestly. Do you have enough runway to compete? Can you afford to lose money for 6-12 months whilst building traction? If your answer is no, then even a good opportunity might not be right for you at this moment. For many founders, especially those running smaller operations, understanding whether app development is accessible for their business size becomes crucial to making realistic decisions about market entry.

Spotting the Signs That You Should Walk Away

Right, let's talk about the hard stuff—knowing when to call it quits before you've even started. I've seen too many clients pour money into markets that were dead on arrival, and honestly, it's brutal to watch. The thing is, your ego can be your worst enemy here; you might love your app idea so much that you ignore all the warning signs screaming at you to stop.

There are some pretty clear indicators that you're heading into dangerous territory. If your market opportunity assessment shows that the top 10 apps in your space are all owned by massive companies with unlimited budgets, that's a red flag. I mean, competing against Facebook or Google in their core areas? That's not brave, its foolish. Similarly, if user acquisition costs in your space are higher than the lifetime value you could reasonably expect from a user—and I've done this calculation more times than I care to remember—you're looking at a business model that simply won't work.

Another sign? When your competitive density research reveals that dozens of well-funded apps have already tried your exact idea and failed. Sure, you might think you'll do it better, but sometimes the market just doesn't want what you're selling. I've worked on apps where we discovered through proper niche viability testing that the target audience was either too small or too reluctant to pay for solutions.

Clear Warning Signs to Watch For

Here's what should make you seriously reconsider moving forward with your app:

• The top apps in your category haven't changed in over two years—this means they've got a stranglehold on the market
• User reviews consistently mention features your competitors don't have, but nobody's built them (there's probably a technical or business reason why)
• Your competitor landscape evaluation shows acquisition costs exceeding £15 per install with poor retention rates
• Every attempt to differentiate your app feels forced or trivial
• You need venture capital just to reach minimum viable market share

If three or more of these warning signs apply to your app idea, take a step back. Sometimes the best decision is to pivot to a related but less saturated market, or to abandon the idea entirely and focus your resources on something with better odds of success.

When the Numbers Don't Add Up

Look, I get it—walking away from an idea you love is hard. But here's the thing: the app graveyard is full of products that should never have been built. If your market saturation analysis shows that breaking even would require capturing 5% of a market where the top player has 60% share and nobody else has more than 3%, you're not being realistic about your chances. The maths just doesn't work, no matter how good your app is.

I've learned over the years that the best entrepreneurs know when to fold. They don't see it as failure; they see it as saving themselves months or years of struggle and hundreds of thousands in development costs. Your competitor landscape evaluation isn't just about understanding who you're up against—it's about honestly assessing whether you can win. And sometimes? The honest answer is no.

When a Crowded Market Is Actually a Good Thing

Here's something that might sound a bit backwards—seeing loads of competitors in your space isn't always the disaster you think it is. Sure, it means you'll have to work harder to stand out, but it also means something really important: theres proven demand.

I mean, think about it this way. If you're looking at launching a fitness tracking app and you see fifty others already doing well, what does that tell you? It tells you that people are actively looking for fitness apps, they're willing to download them, and—most importantly—they're probably spending money on them. A crowded market means someone's already done the hard work of educating users about why they need this type of app in the first place.

Compare that to trying to create an entirely new category of app. You're not just building the product; you're also having to convince people they need it at all. That's bloody expensive and time-consuming, and most startups don't have the resources for it.

The key is understanding that competition validates your market—it doesn't invalidate your opportunity. When I see a crowded space, I actually get a bit excited because I know the infrastructure is there: the app stores understand the category, review sites have sections for it, and users know what search terms to use when they're looking for a solution. Take meditation apps like Headspace and its competitors—the category is absolutely packed, but there's still room for apps that serve specific niches or offer unique approaches to mindfulness and mental health.

What matters is whether you can do something different enough or better enough to carve out your slice. And honestly? Most apps in crowded markets aren't actually that good. They have poor reviews, clunky interfaces, or they've stopped innovating altogether. That's your opening—not an empty market, but a market full of mediocre solutions that you can improve on.

Validating Your Market Position With Real Data

Right, so you've done your research and you think there's space for your app—but how do you actually prove it? I mean, gut feelings are great and all, but they don't hold up when you're spending real money on development. You need proper data to back up your assumptions, and honestly, gathering this information is easier than most people think.

Start with Google Trends; its free and shows you whether interest in your apps category is growing or shrinking over time. Compare your main search terms against competitor brand names to see whats gaining traction. If the trends pointing downward, that's a red flag you cant ignore. Actually, I've seen too many clients skip this step and regret it later when they realise they've built something for a dying market.

Real User Testing

But here's the thing—search data only tells you what people are looking for, not whether theyd actually use your solution. You need to put something in front of real humans and watch what happens. Build a simple landing page explaining your app idea and run some paid ads to it (you don't need a huge budget, even £100-200 can give you meaningful results). Track how many people sign up for your waiting list or express genuine interest. The conversion rate will tell you more than any market report ever could. When it comes to actually building the thing, you'll also want to consider whether to code it yourself or use no-code platforms, which can affect both your timeline and budget significantly.

The best validation comes from people willing to give you their email address or, even better, pre-order access to something that doesn't exist yet.

Survey your target users too; ask them what they're currently using to solve the problem your app addresses. If they say "nothing really" or struggle to answer, you might be onto something. If they rattle off three apps they love? Well, you've got your work cut out for you convincing them to switch. The data doesn't lie—it just needs interpreting with a healthy dose of realism about what you're walking into. Once you've validated your concept, you'll need to think about timing your launch perfectly to maximize your chances of success in that crowded market.

Conclusion

Look, I've been doing this long enough to know that figuring out if your market is too crowded isn't a simple yes or no question—it's more like a series of questions you need to keep asking yourself. And honestly? Sometimes a crowded market is exactly where you want to be, because it means theres real demand there. Other times, you'll spot the warning signs early and save yourself a lot of headaches (and money).

The thing is, every successful app I've built has faced competition. Every single one. But the ones that succeeded weren't necessarily in empty markets—they just had something different to offer. They understood their specific users better than anyone else did, they found gaps that others had missed, or they simply executed better than their competitors. Market research isn't about finding a completely empty space; its about understanding whether you can carve out your own territory within an existing one.

What I want you to take away from this is that validation is everything. Don't just assume your idea will work because you think it's good—test it, measure it, and be prepared to pivot if the data tells you something different. Talk to real potential users. Look at what your competitors are doing wrong, not just what they're doing right. Calculate your numbers honestly, even when they're uncomfortable.

And here's the thing that people often forget: choosing to walk away from an app idea because the markets too saturated isn't failure—it's smart business. I've turned down projects before because the numbers didn't make sense, and I've never regretted those decisions. But I have regretted the times I ignored the warning signs and built something that struggled to find its place. Trust your research, trust the data, and most importantly, trust yourself to make the right call for your situation.
