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.

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.”

Our process

How your Flutter app goes from idea to launch

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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.

FAQ.

Here are some of our most frequently asked questions and answers.

What is Flutter?

Flutter is a free, open-source toolkit from Google for building apps. Developers write the app once, in a language called Dart, and Flutter turns it into apps for iPhone, Android, the web and desktop. Google uses it for its own apps. So do startups and large companies around the world.

Will a Flutter app feel like a normal iPhone or Android app?

Yes. Flutter apps compile to native code and follow the scrolling, navigation and gestures people expect on each phone, so most users won’t notice any difference. Every app in our portfolio is a Flutter app.

Can a Flutter app use the camera, location and payments?

Yes. Plugins give Flutter apps access to the camera, GPS location, push notifications, in-app payments, Bluetooth and more. When a plugin doesn’t cover something, we write the platform code ourselves. So if your idea depends on one particular feature, we’ll check it on the first call.

Can you build an MVP in Flutter and grow it later?

Yes, and it’s how we prefer to work. We build an MVP, the smallest version of your app that real users can try. Then we add features based on Mixpanel data and user feedback. The same Flutter code grows with your app, so you don’t have to start again when you’re ready for more.

Who owns the code and designs?

You do. Once the project is paid for, the code, designs and intellectual property of your Flutter app belong to you. If you later want to take the app to another team or bring development in-house, it’s yours to take.

Can you take over or rebuild my existing app?

Yes. We can take over an existing app and keep it running. Or, if two separate apps are costing too much to maintain, we can rebuild it in Flutter. We look at your current code first, then tell you which option suits your budget.

How secure are Flutter apps?

A Flutter app is as secure as the way it’s built. We use encrypted connections, keep secret keys out of the app itself, and put proper login and permission checks on the backend. For apps that handle payments or personal data, we also follow Apple’s and Google’s security guidelines.

Do you support the app after launch?

After launch, we fix bugs and keep your app working with new iPhone and Android versions. We also add features as your users ask for them. You can keep us on a monthly plan or get help as and when you need it through our support and maintenance service.

Can you build a web or desktop version too?

The same Flutter code can run on the web, Windows and macOS as well as iPhone and Android, so we can build any of these from one codebase. If you need a larger web platform alongside your app, our web app development team can build that too.
