Flutter App Development in London
Expert Flutter app developers in London building high-performing iOS and Android apps from one product team — with Play and App Store as two real release trains.
One codebase, two stores
Flutter apps when two platforms must ship together
Flutter App Development
iOS + Android Release
Platform-aware UI
Native Channels & API
Our work process — from shared design to dual release
Fit Check & Requirements
Is Flutter the right bet vs native vs React Native? We decide on hiring, OS features and v1 stores.
Prototyping for Both Platforms
Design tokens and flows that survive iOS and Android — not a Dribbble clone of one OS.
Flutter Development
Slices with TestFlight and internal Play together. Shared logic, honest native gaps.
Platform QA
Permissions, payments, notches, back gesture, mid-range Android performance.
Dual Store Launch
Stagger if review risk differs. Two listings, two reviews, one product org.
Why Flutter is a bet on one team — not zero native work
Camera, background, payments and store rules still exist twice. Flutter saves a second full native crew when the UI can be unified. It does not delete Play Console or App Store review.Design Dev ships Flutter when the commercial case is two platforms, one product organisation. If the app is Android-only, native Android is often cleaner — and we will say so.
- Honest platform fit before a single widget
- Design that survives both operating systems
- Platform channels for native gaps
- CI for both artefacts
- Crash reporting on iOS and Android
- Store listings treated as two jobs
- Performance budgets on mid-range Android
- A dual-store release calendar

QA Across Devices
Notches, back gesture, mid-range Android, iOS review risk.

A London team that will talk you out of Flutter when native is cheaper
Design Dev uses Flutter when two platforms and one product team is the point. Store work still happens twice. We plan for it — and we will recommend native or React Native when hiring and OS features say so.

Product before pixels
Journeys, store rules and backend are planned with the app — not after a demo build.
Platform choice that fits
Native, Flutter, React Native or PWA is a commercial decision, not a trend.

Listings, review, performance and QA on real devices — not a one-off APK email.
