How long does it take to build a Flutter app?

A simple Flutter app can be built in 3-4 weeks. Medium-complexity apps take 4-6 weeks, and complex apps take 8-12 weeks. Since Flutter builds for both platforms simultaneously, these timelines are roughly half what native development would require.

The Problem

Native Development Is Expensive

Building separate apps for iOS and Android doubles your development cost, maintenance burden, and time to market. For most startups and businesses, native development is simply not cost-effective.

Double the Budget

Two separate codebases mean two separate development costs. A £15K native iOS app becomes £30K when you add Android.

Double the Timeline

Even with parallel teams, native development takes longer because every feature must be built, tested, and debugged twice.

Ongoing Maintenance

Every update, bug fix, and new feature must be implemented in both codebases. Maintenance costs compound over time.

The Solution

Flutter: One Codebase, Half the Cost

Flutter lets us build native-quality apps for iOS and Android from a single codebase. You get the same performance and user experience at a fraction of the cost.

30-40% Cost Savings

One team, one codebase, two platforms. Flutter development typically costs 30-40% less than building separate native apps.

Faster Delivery

Build features once and deploy to both platforms. Apps launch in 30 days or less, not months.

Native Performance

Flutter compiles to native ARM code. No web views, no compromises. Your app performs identically to a native-built application.

Lower Maintenance

One codebase to maintain means updates, bug fixes, and new features are implemented once and deployed everywhere.

FAQ

Flutter Cost Questions

Flutter app development in the UK starts from £8,000 for a simple app with core features. Medium-complexity apps typically start from £15,000, and complex apps with advanced integrations start from £25,000. Flutter is 30-40% cheaper than building separate native iOS and Android apps.

Yes. Flutter uses a single codebase for both iOS and Android, which typically saves 30-40% compared to building two separate native apps. You also save on ongoing maintenance since there is only one codebase to update and debug.

Yes. Flutter compiles to native ARM code, delivering the same performance as native iOS and Android apps. The UI is rendered directly using the device GPU, so animations are smooth and the app feels native to each platform.

A simple Flutter app can be built in 3-4 weeks. Medium-complexity apps take 4-6 weeks, and complex apps take 8-12 weeks. Check our app timeline guide for more details.

Yes. Many businesses migrate their existing native apps to Flutter to reduce maintenance costs and speed up feature development. We can rebuild your existing app in Flutter while maintaining all current functionality and improving the user experience.
