How do I know if my app idea is worth investing in?

One of the easiest traps to fall into is becoming attached to the solution before you have properly understood the problem. You might have a clear idea of what your app should do, but that doesn’t necessarily mean you have identified a problem people genuinely want solved.

Imagine you have an idea for an app that helps independent tradespeople manage their jobs, customers and invoices. At first glance, that sounds useful. But “an app for tradespeople” is a solution description, not a problem statement. The more important question is what is actually going wrong today.

Are tradespeople losing work because they struggle to respond to enquiries quickly? Are they spending hours every week organising appointments? Are invoices being forgotten? Are customers frustrated because they don’t know when someone is arriving? Are existing tools too complicated, too expensive or designed for larger businesses?

The answers lead you somewhere much more useful.

A strong product opportunity usually starts with a problem that is frequent enough, painful enough or valuable enough for someone to want to change the way they currently do things.

That distinction matters because the latest data from CB Insights reinforces just how important product-market fit is. Its 2026 analysis of 431 VC-backed companies that shut down found poor product-market fit was cited in 43% of failures. Interestingly, running out of capital appeared in 70% of failures, but CB Insights describes this as often being the final consequence rather than the underlying problem.

In other words, spending more money isn’t necessarily going to rescue an idea that people don't actually need.

Ask yourself:

• What specific problem am I solving?
• Who experiences that problem?
• How often does it happen?
• How frustrating, expensive or time-consuming is it?
• What happens if the problem isn't solved?
• How are people dealing with it today?
• Why would they change what they are currently doing?

If you can answer those questions clearly, you’re already in a much stronger position than someone who has simply started with a list of features.

The next question is deceptively simple: who is this app for? “We’re targeting everyone” might sound like a great business opportunity, but it makes it incredibly difficult to build a product that genuinely works for anyone.

Different people have different needs, expectations and reasons for using an app. A product designed for a busy parent booking children's activities will need to solve a very different problem from one designed for a logistics manager managing a fleet of vehicles, even if both involve booking and scheduling.

We often encourage product owners to think about their audience in terms of the people who experience the problem most frequently and most severely.

That group is usually much more valuable to understand than a huge theoretical audience. Start talking to them. Ask them things like:

• How they currently deal with the problem
• What they find frustrating
• What they have already tried
• What they pay for today
• What would make them switch

Most importantly, listen to what they actually do rather than simply asking whether they like your idea.

There is a big difference between someone saying, “That sounds like a great idea,” and someone saying, “I have this problem every week, I currently spend £200 a month trying to solve it, and I would switch if you could do this.” The second conversation gives you something you can work with.

Once you understand the problem and the audience, you need to establish whether there is enough demand to make the opportunity worthwhile. This doesn't necessarily mean you need a huge market. A niche product can be an excellent business if the problem is valuable and the economics work.

What you need is evidence that the problem exists beyond your own experience or a handful of people you know. There are several ways to look for that evidence.

Search for conversations around the problem. Look at Reddit discussions, industry forums, social media, reviews of competing products and customer complaints. Speak to potential users directly. Look at search behaviour where relevant. Investigate industry reports and market data. If it is a B2B product, speak to people who actually make purchasing decisions.

You are looking for patterns.

If ten people independently describe the same frustration, that's interesting. If fifty people describe it and are already paying for an imperfect solution, that's considerably more interesting.

Existing behaviour is particularly useful here. People already spending time or money trying to solve a problem are giving you a signal that the problem has some value.

And remember that the app market itself is enormous, but that doesn't mean every idea has an easy route to users. Apple's latest App Store Transparency Report lists more than 2.17 million apps on the App Store, alongside an average of more than 929 million weekly app downloads.

There is clearly an enormous appetite for apps. There is also an enormous amount of competition for people's attention. That is why “there is a market for apps” isn't enough evidence. You need to understand whether there is a market for your particular product.

Finding competitors can feel like bad news when you've spent months developing an idea. In reality, competition can be one of the most useful signals you have. If someone has already built something similar, it proves that other people have recognised the problem too.

The question is whether there is room for another solution. Start by identifying your direct competitors, but don't stop there. Your biggest competitor might not be another app, it could be:

• a spreadsheet
• an email
• a WhatsApp
• a paper form sitting on someone's desk
• a process involving three different systems and a member of staff spending half a day putting information together manually

These alternatives tell you a lot about what your product needs to replace or improve. Then look at what existing products do well and where they fall short. Read their reviews. Look at complaints. Understand their pricing. Try the products yourself if you can. Pay attention to the moments where users seem to struggle.

You aren't looking for a reason to say, “Our app will have more features.” You are looking for a reason for someone to choose you.

Perhaps existing products are too expensive for smaller businesses. Perhaps they're difficult to use. Perhaps they were designed for desktop rather than mobile. Perhaps they solve 20 different problems when your audience only needs three solved exceptionally well. That is where your opportunity might sit.

Once you've mapped the competition, you should be able to answer a fairly uncomfortable question:

Why would someone choose this app instead of what they already use?

“It's easier to use” is a start, but you'll want to understand exactly why. Maybe your app saves a particular group 30 minutes every day. Maybe it removes a frustrating manual process. Maybe it brings several disconnected services together. Maybe it gives customers something they currently can't do. Maybe your advantage comes from your existing industry knowledge, relationships, data or distribution.

Your differentiator doesn't have to be a revolutionary piece of technology. Sometimes the best products win because they understand a particular audience better than anyone else.

That is especially important when you're entering a crowded category. With more than two million apps already available on Apple's App Store, simply being another app that performs an existing function isn't much of a strategy. Your idea needs a clear reason to exist.

An app can have thousands of users and still be a poor investment. That might sound surprising, but downloads aren't the same thing as business value. Before development begins, think about how the product is going to make money, save money or create another measurable benefit for the organisation behind it.

For a consumer app, that could mean subscriptions, purchases, advertising, transaction fees or another revenue model. For a B2B product, it might be a monthly licence, implementation fee, transaction charge or a reduction in operational costs.

For an internal business app, the value might come from reducing administration, improving productivity, reducing errors or helping employees complete work more quickly. The important thing is being able to connect the product to a business outcome.

For example, imagine an app costs £100,000 to develop and maintain. If the product is expected to generate £10,000 a year, you have a very different investment proposition from an app that could generate £500,000 a year or save the organisation £250,000 through operational efficiencies.

You don't need to know the exact numbers on day one, but you do need to start thinking about them.

Consider:

• How will the product generate revenue?
• Who is paying?
• What are they paying for?
• How much could a customer be worth?
• How much will it cost to acquire that customer?
• What will it cost to operate the product?
• How much will ongoing development and support cost?
• How long might it take to reach profitability?
• What would make the investment worthwhile?

These questions also help you avoid a common mistake: deciding that the app is worth building because the development cost seems affordable, rather than because the underlying business case makes sense.

Getting someone to download an app is one thing. Giving them a reason to come back is another. This is where you need to think carefully about the behaviour your product is trying to create.

Some apps naturally have frequent use. A banking app, messaging app or travel app might be opened regularly because the underlying need keeps returning.

Others solve occasional problems. An app for booking a holiday might only be used heavily at certain points in the year, but that doesn't make it unsuccessful. Its value might come from helping someone complete an important task particularly well.

So don't automatically assume that daily active users are the only measure of a successful app. Instead, ask what successful usage looks like for your particular product. What action demonstrates that someone has received value?

Is it completing a booking? Sending an invoice? Checking a journey? Uploading a document? Making a purchase? Returning to compare information? That action should influence how you design the product and what you measure after launch.

The platforms themselves recognise that engagement and retention matter. Google Play, for example, evaluates app quality using signals including user loss rate, daily active users and monthly active users, alongside factors such as usability, performance and content depth.

And retention can be a harsh reality check. AppsFlyer's 2025 uninstall benchmark, based on 1.3 billion installs across 2,200 apps, found that more than half of installed apps were uninstalled within 30 days.

That doesn't mean your app needs to be opened every day. It means the experience needs to deliver the value users expected when they installed it.

This is the point where the conversation needs to move from “Would people want this?” to “Can we realistically build and operate it?”

A product can be commercially attractive but technically difficult. It can also be technically straightforward but commercially weak. Both sides matter.

You need to consider things like integrations, APIs, data, security, authentication, payments, third-party services, infrastructure, regulatory requirements and the platforms you need to support.

For example, an app that simply displays information from your own database is a very different technical proposition from one that needs to connect with several external systems in real time.

An app involving financial transactions will have very different security and compliance considerations from an app for sharing recipes. An app used by employees in warehouses, hospitals or transport operations might need to work in areas with poor connectivity, support unusual hardware or handle complex permissions.

These details can significantly affect cost and timescales.

This is one reason we don't recommend treating development as the first step. Before you commit to a build, you want enough technical understanding to know what you're actually committing to.

A technical discovery can uncover risks early, identify opportunities to simplify the product and help you understand where the real complexity sits. Sometimes the result is reassuring: the idea is very achievable. Sometimes you discover that a particular feature will cost far more than expected. And sometimes the best outcome is finding a different way to achieve the same user outcome without introducing unnecessary complexity.

This is where the idea of an MVP becomes important. An MVP isn't simply the cheapest version of your app. It is the smallest version of the product that allows you to test the most important assumptions behind the business.

If your entire business depends on people being willing to pay for a particular service, your MVP should help you test that. If the biggest uncertainty is whether customers will change their existing behaviour, your MVP should help you test that. If the biggest risk is a complicated technical integration, you may need to prove that integration before investing in the rest of the product.

This is why we prefer to think about product development as a journey of reducing uncertainty rather than simply moving through a list of features. You start with what you know. You identify what you don't know. You work out which unknowns could seriously affect the business. Then you test those assumptions before spending heavily on the parts that depend on them. That approach can save an enormous amount of time and money.

When you're deciding whether to invest in an app, it's easy to focus entirely on the cost of building it. But there are really two costs to consider: the cost of building the wrong thing and the cost of finding out what works. Those aren't the same.

Investing in discovery, research, prototyping and technical planning might add cost at the beginning, but it can also prevent you from committing a much larger budget to an idea that hasn't been properly tested.

This is something we see repeatedly with product owners. The temptation is understandable: you've got an idea, you want to see it become real, and development feels like the exciting part. But the most valuable work can happen before a single line of production code is written.

That is why our own process puts significant effort into understanding the product before development begins. We want to understand the users, the problem, the opportunity, the experience and the technology so that when development starts, we're making informed decisions rather than expensive guesses.

Before deciding whether your idea is worth investing in, decide what would make you call it successful. This sounds obvious, but it is surprisingly easy to build an app without agreeing what success means, such as:

• Is the goal to reach 10,000 users?
• Generate £500,000 in annual revenue?
• Replace an existing system?
• Reduce customer support calls?
• Increase conversion?
• Improve employee productivity?
• Create a new revenue stream?
• Enter a new market?

The answer will influence almost every product decision you make. A product designed to generate revenue needs a different strategy from an internal app designed to reduce operational costs. A product intended to support an existing customer base needs a different acquisition strategy from a new consumer marketplace starting from zero.

The clearer you are about the outcome, the easier it becomes to decide what belongs in the product and what doesn't.

By this point, you might have realised that there isn't a simple “yes” or “no” test. A worthwhile app idea usually sits at the intersection of several things. There is a real problem. A clearly defined group of people experiences that problem.

Those people care enough about it to change their behaviour. There is evidence that demand exists. The competitive landscape leaves room for your product. You have a credible way to reach your audience. The product can create enough commercial or operational value to justify the investment. The technology is achievable within sensible constraints.

And, perhaps most importantly, you have a way to test the riskiest assumptions before committing to the full product. If several of those pieces are missing, that doesn't automatically mean you should abandon the idea. It might mean the idea needs changing.

Perhaps your audience is too broad. Perhaps the problem is real but not painful enough. Perhaps your business model needs work. Perhaps there is a much smaller first version that would let you test the opportunity. Perhaps your original idea isn't quite right, but the research uncovers a much stronger opportunity sitting next to it.

That's why validation shouldn't be treated as a pass-or-fail exercise. The goal is to learn enough to make a confident decision.

If you came to us with an app idea tomorrow, we wouldn't want to rush straight into development. We'd want to understand what you're trying to achieve, who you're trying to help and why you believe the opportunity exists. We'd look at the problem, the audience, competitors, business model and user journey, before getting into the technical considerations that could affect the product.

From there, we could start separating assumptions from evidence. Some ideas will become stronger as you investigate them. Others will need refining. Occasionally, research will tell you that the original idea isn't worth the investment at all.

And although that can be difficult to hear, discovering it before you've spent a significant amount of money is a much better outcome than discovering it six months after launch.

The best product decisions aren't always the ones that get you into development fastest. They're the ones that give you enough confidence to know what you're building, who you're building it for and why it deserves to exist.

So, if you've got an app idea sitting in the back of your mind, don't start by asking, “How much will it cost to build?” Start with a more useful question:

“What would I need to know to be confident that this is worth building?”

That's where the real product journey begins.
