Frequently, people come to us with a brilliant app idea and a budget that makes us wince. They’ve seen what apps can do. They’ve read the success stories. And they want in — for as little as possible.
So let’s be completely honest with you. Because in 12 years of building apps, we’ve learned that the most useful thing we can do for a budget-conscious client isn’t to take their money and start building. It’s to ask the right questions first.
The First Question We Always Ask
Before we talk budget, before we talk timelines, before we talk anything technical — we ask this:
What are the minimum features you need to make this actually work?
Not the features you want. Not the features your competitor has. Not the features you might need one day. The bare minimum to make the core idea function.
This single question changes everything. It’s the difference between a project that gets built and a project that stalls, between something that launches and something that sits in a spreadsheet forever.
Everything else can be added later — when the app is live, when users are giving you feedback, when it’s starting to generate income. But first, it has to exist.
What “Tight Budget” Actually Means for an App
Here’s where we need to be straight with you, because most articles on this topic dance around the numbers.
In our experience, a low budget for an app is around £15,000. A higher-budget app starts from £50,000 and goes up — sometimes significantly. There’s no real ceiling.
We have managed to build and release a working app to the App Store in a single day. It was extremely basic, but it was real, it was live, and it cost somewhere in the region of £500–£1,000. That’s not a normal project — it was a proof of concept, stripped to the bone.
The point is: the spectrum is enormous. And where your project sits on that spectrum depends almost entirely on what you’re asking the app to do.
If you have less than £15,000 to spend, a well-built website — or an addition to your existing website — will almost certainly serve you better. We say that knowing it might cost us a project, but we’d rather give you that honest steer than take your money and deliver something that doesn’t really do what you need.
The Hidden Costs Nobody Warns You About
The build cost is just the beginning. This is where we see budgets get quietly destroyed.
Third-party integrations — push notifications, payment processing, mapping, analytics — all carry costs that aren’t immediately obvious. Each integration takes development time and often has ongoing subscription fees.
Hosting and server fees — if your app does anything beyond sitting on someone’s phone (stores data, handles user accounts, processes anything in the background), you’ll need a server. That’s a monthly cost, ongoing, forever.
App Store registration — Apple charges a £99 annual developer fee. Google Play is a one-off £25. Small numbers, but ones people forget entirely.
Maintenance — this is the big one. Your app doesn’t exist in a frozen moment in time. The libraries and packages your app relies on are updated constantly. Integrations change. Operating systems release new versions. Keeping everything working, secure, and compatible costs real money — anywhere from a few hundred to a few thousand pounds per month depending on complexity. This isn’t optional. Ignore it, and the app breaks.
When you’re working out what you can afford, build all of this into your thinking from the start.
A Lesson in Scope Creep
We had a client who wanted to swap out one piece of functionality for something they believed was similar. In their mind, it was a like-for-like change. In practice, it required significant additional development work — time, cost, and delay they hadn’t anticipated.
This is one of the most common ways budgets collapse: not through big decisions, but through small ones that turn out not to be small at all.
A focused plan, agreed upfront, protects everyone. When clients stick to the minimum viable feature set and resist the urge to swap or add as the project progresses, projects come in closer to budget and closer to schedule. When they don’t, costs spiral — sometimes dramatically.
What About No-Code and Low-Code Tools?
Tools like Bubble, Glide, and FlutterFlow have genuinely changed what’s possible on a smaller budget. They can cut development time — and therefore cost — considerably.
But they come with a trade-off: they don’t allow you to be as specific or custom as pure coding. If your app needs to do something unusual, something very precise, or something that differentiates you technically from competitors, you’ll hit the ceiling of these tools quickly. In addition to this, when things go wrong with these tools or third-party add-ons (and they do go wrong), you can be stuck unable to progress.
For straightforward apps with standard functionality, they’re worth considering. For anything more complex or bespoke, they can end up costing more in workarounds than they save in build time.
The Question We Ask That Other Developers Usually Don’t
If someone comes to us with a tight budget and a clear problem they’re trying to solve, the first thing we genuinely consider is:
Do you actually need an app for this?
Would a website do the job? Could this be built into your existing website? These aren’t rhetorical questions — they’re genuine ones.
Apps have real advantages: push notifications, offline functionality, access to device features, app store discoverability, better performance & speed, superior user experience, enhanced brand presence and customer loyalty and effective revenue models to name but a few. But they also carry all the costs we’ve described above. If a website solves the problem just as well, it’s almost always the more cost-effective path — especially when budget is tight.
We’d rather help you spend your money well than spend it on the wrong thing.
So You Have £5,000 to Spend
Let’s be practical. If someone came to us tomorrow with this budget, here’s what we’d do: sit down with the proposal and give genuinely honest feedback on whether any of it — or all of it — is achievable for that amount.
Sometimes the answer is yes, if the scope is tight enough. Sometimes the answer is: here’s what we can do for that, and here’s what it won’t include. And sometimes the most helpful thing we can tell you is: save up a bit more, or consider a website first.
£5,000 for an app means something very basic — no server-side functionality, no complex integrations, something close to the bone. That’s not necessarily a bad thing. But you need to know it going in.
The Honest Summary
Building an app on a tight budget is possible — but only if you define “tight” realistically, plan your features ruthlessly, and account for every cost, not just the build.
Start with the minimum. Launch it. See what works. Add to it when the project starts generating income. That’s not a compromise — it’s smart product development.
If anyone tells you they can build you a full-featured app for £2,000, ask them what’s not included. Check what you’re getting.
