London

Flutter is the fastest way to ship a quality app on iOS and Android from one codebase. Our London Flutter team uses Dart 3, Riverpod, and modern null-safe architecture to ship MVPs in 12 weeks and consumer-grade apps in 20. Pixel-perfect on both platforms, single team, half the cost of native.

How we work.

We start with a two-week discovery sprint — user flows, technical architecture, fixed-price scope. Every Flutter build uses our reference stack: Riverpod for state, Drift for local persistence, Firebase or Supabase for backend, and a CI/CD pipeline that ships TestFlight + Play Console builds on every merge.

For MVPs we ship a working app in 12 weeks: 5–8 screens, authentication, push notifications, payments, and analytics wired in. For consumer-grade apps we extend to 20 weeks with deep integrations, offline-first architecture, and platform-specific polish (Cupertino on iOS, Material 3 on Android).

Senior Flutter engineers only. No outsourcing, no juniors learning on your project. Every line of Dart is reviewed by a senior. You own all source code, signing certificates, App Store and Play Console accounts, and Firebase project from day one.

FAQ.

One codebase ships to both platforms. Same UI, same business logic, half the engineering cost. Modern Flutter (3.x) is indistinguishable from native for 95% of consumer apps. Native is still the right call for AR, complex camera workflows, or platform-specific deep integrations — we'll tell you upfront if your project needs it.
A working MVP: 5–8 core screens, sign-up/login, push notifications, in-app payments (Stripe or RevenueCat), basic analytics, and TestFlight / Play Console submission. Backend uses Firebase or Supabase for fastest time-to-launch. Anything more (multi-region, complex offline sync, video processing) sits in the next tier.
First TestFlight build typically lands in week 4. Internal testing throughout. Public beta around week 10. Submission to App Store and Play Store week 12. We schedule App Store reviews into the timeline — Apple's review queue is unpredictable but we know the patterns.
Yes. We submit, respond to reviewer feedback, and stay on point until the app is live. We've shipped 40+ Flutter apps through both stores and rarely get rejected on first submission. Apple developer account stays in your name — you own it.
Yes — we do takeover audits regularly. Flat-fee £499 audit, written report on architecture quality, technical debt, security gaps, and a path to migrate or extend. Many takeovers we work on were built by offshore teams that left the codebase in a difficult state. We've seen it all.
