Building native for iOS and Android is doubling your cost.
Two codebases, two teams, two timelines. Every feature has to be built, tested, and maintained twice — and your budget is stretching further than it should.
Launch your mobile app on both platforms with a single codebase — cutting your development time and cost in half. Shape's Flutter FastTrack delivers polished, production-ready mobile apps for startups and SMEs, built by senior UK developers using Flutter. From concept to app store in weeks, not months.

Two codebases, two teams, two timelines. Every feature has to be built, tested, and maintained twice — and your budget is stretching further than it should.
You know your users are on mobile, but you can't justify the investment to build separate native apps. Meanwhile, your competitors are already in the app store.
You've looked at quick fixes — web views, PWAs, low-code app builders — but the result feels clunky, slow, and nothing like a real native app. Your users notice.
Maybe you've tried before. A freelancer, an offshore team, or an agency that promised the world. The app was late, buggy, and never quite right.
Flutter FastTrack is Shape's cross-platform mobile app development service for founders and SMEs who want to launch on iOS and Android without the cost and complexity of native development. We use Flutter — Google's production-grade framework — to build a single codebase that delivers truly native performance on both platforms.
You get a real app. We handle the complexity.
Flutter compiles to native ARM code — your app looks, feels, and performs like a native app on both iOS and Android. No compromises.
One codebase means one team, one build, one testing cycle. You get both platforms for significantly less than building native twice.
Launch on both app stores in weeks, not months. Flutter's rapid development cycle means you're live while competitors are still briefing agencies.
One codebase to update, one set of tests to run, one deployment pipeline. New features ship to both platforms simultaneously.
A clear, structured process designed to get your app live on both platforms as fast as possible.
01
We start with a free conversation to understand your app idea, your users, and your goals. We'll advise on whether Flutter is the right fit and map out the initial scope. No commitment required.
02
We design the mobile UX and create an interactive prototype you can tap through on your phone. You'll see how the app looks and feels on both platforms before we write a single line of code.
03
Our senior Flutter developers build your app in short sprints. You see real progress every week, test on real devices, and have input at every stage.
04
We handle the full app store submission process for both Apple and Google. You launch with a polished, production-ready app and a roadmap for future development.

"Our team use both iphones and android phones, we needed an app that worked for everyone on the team not just half of them."
— Julie, Operations Manager, PPHCare
"I thought I needed an app but once I spoke with Shape they explained that we could launch with a mobile first website and save time."
— Hatty, CEO, Orlune
We've been building software products for over ten years. Now we use AI-accelerated workflows to deliver faster, without cutting corners on quality.
