Flutter App Development
Flutter app development for founders and startups
With Flutter app development, we build your app once and release it on iPhone and Android at the same time. That means one team, one budget and a working first milestone in under four weeks.
What we build
Flutter app development, from first idea to the app stores
We take care of the whole app. That covers the screens your users see, the backend that stores their data, and logins and payments. It also covers the release on the App Store and Google Play, so you deal with one team from the first sketch to launch day.
Our apps are built with Flutter, Google’s free, open-source toolkit for building apps from a single codebase. Most founders come to us for an iPhone and Android app. But the same code can also run on the web and desktop, so adding a web version later doesn’t mean starting again.
Every app in the portfolio below was built with Flutter, including Scouts Capital, Motion Shield and Mindful You Meditations. If you need help with the look and feel too, our UI and UX design team works on the same project.
Why Flutter
Why founders build their first app in Flutter
Founders usually come to us with one budget and a lot to prove. Flutter app development helps with both. You pay for one app, not two.
-
One Flutter app for iPhone and Android
Separate native apps mean two codebases, two sets of developers and two bills. With Flutter we write the app once and ship it to both stores, so your money goes into features your users will notice.
-
Changes appear almost instantly
While we work, code changes show up on screen within a second or so. That means when you ask for a tweak on a call, we can often show you the result before the call ends.
-
Fast and consistent on every phone
Because Flutter apps compile to native code and draw every pixel themselves, your app runs smoothly. It also looks the same on a brand-new iPhone and on an older Android phone.
How we work
Start with a small Flutter app, then let your users show you what's next
The biggest risk for a new app isn’t the code. It’s spending months on features nobody wants. So we help you choose the few features that prove people want your idea, build those first and get them in front of real users.
Mixpanel analytics comes as standard. From the first release, you can see which screens people use and where they give up. Together with feedback from your users, that tells us what to build next, instead of guessing.
Tobias Schaller, Director of Scouts Capital, put it simply in his Clutch review: “I’m impressed by their time efficiency.”
-
A first milestone in under four weeks
Your build is split into milestones you can test on your own phone. You can have the first one in your hands in under four weeks, and very small apps can be finished in four to six weeks.
-
AI speed, checked by people
AI helps us prototype screens, write code, create tests and review changes, which saves hours of routine work. But none of it runs on autopilot. A developer checks and approves every change, so the quality is still down to people.
-
Code and designs you own
Once the project is paid for, the code, designs and intellectual property belong to you. If you ever move to another team or hire your own developers, the app goes with you.
Our process
How your Flutter app goes from idea to launch
-
Culture call
It starts with a video call about your idea, your users and what success looks like for you. If our values match, we move on to a quote.
-
Free quote in 48 hours
Within 48 hours you get a free, detailed quote. It splits the cost and timeline into milestones, so you know what you're paying for at each stage.
-
Clickable designs
We design the key screens and turn them into a prototype you can tap through on your phone. Revisions are unlimited, so we keep going until it feels right.
-
Build in milestones
One milestone at a time: you test each one on your own device and sign it off before we start the next.
-
Launch on both stores
Together, we prepare your App Store and Google Play listings, and then we handle the submission. After that, your app goes live for iPhone and Android users.
-
Measure and improve
After launch, we look at the Mixpanel data and your users' feedback together and plan the next release. Support and maintenance are there whenever you need them.
Cost
How much does a Flutter app cost in the UK?
A Flutter app from Ingenious App Studios starts from about £5,000, and a typical first version costs around £10,000. The final price depends on how many screens and features you need. A backend of its own, or extras such as payments and maps, also add to it.
The cost of Flutter app development stays low because you pay for one codebase instead of separate iPhone and Android apps. Starting with a small first version saves even more, since you only pay for the features that prove your idea.
Your free quote arrives within 48 hours of our first call. For a wider look at app budgets, read our guide to how much it costs to develop an app.
Timeline
How long does it take to build a Flutter app?
With Ingenious App Studios, the first working milestone of your Flutter app can be ready in under four weeks. Very small apps can be finished in four to six weeks. Bigger apps take longer, so we split them into milestones you can test as we go.
In practice, the time Flutter app development takes depends on how many features you need and how custom the design is. It also depends on which other services the app connects to. Your quote sets out each milestone and when to expect it, so you can plan your launch and marketing around it.
Is it right for you?
When a Flutter app isn't the right choice
Most of the apps founders bring to us suit Flutter, from marketplaces and booking apps to fintech and community apps. But it isn’t the only option, and we’ll tell you on the first call if another route fits your idea better.
For a closer look at the trade-offs, read our guide on whether Flutter is worth choosing.
-
Your team already uses React Native
If you already have developers who work in React or React Native, building with the tools they know can be quicker and cheaper for you in the long run.
-
Your app is mostly a 3D world or a game
Animation and simple games work well in Flutter. However, when the whole product is an immersive 3D game, a dedicated game engine such as Unity is usually the better tool.
-
You need brand-new phone features at launch
When Apple or Google release a new feature, native apps can use it straight away. Flutter normally catches up quickly, but if your launch depends on it, we'll plan around that from the start.
