iOS, Android, and Web developed separately – three teams, three codebases, three release cycles.
The same features are built three times, the same bugs are fixed three times.
LEAN Evolution: Cross-Platform App Development
One App, All Platforms
Three teams, three codebases, three times the bugs – each platform brings its own quirks, edge cases, and issues. The solution: Cross-Platform Apps with Flutter - one codebase, native performance on all platforms.
What is it about?
For companies needing an app for iOS, Android, and Web – without triple the budget, without three teams. For products that need to hit the market quickly and want feature parity across all platforms.
Your benefit:
- 100% Feature Parity ↑
- approx. -40% Time-to-Market ↓
- up to -50% Development Costs ↓
Are you familiar with?
Android has had the feature for three weeks, iOS is lagging behind, Web doesn't have it at all
Different behavior on different platforms confuses users and support.
Finding, building, and retaining specialized developers for each platform not only triples personnel costs but also the hiring effort.
What does this bring you?
One codebase for iOS, Android, and Web
Features are built once and run on all platforms. No lagging, no "coming in the next sprint for the other platform."
Native performance without native effort
Flutter compiles to native code. Smooth animations, fast loading times, platform-specific look & feel – without three separate development streams.
Faster to Market
One team, one release cycle. Features go live simultaneously on iOS, Android, and Web. You save not only on the eliminated coordination meetings. Time-to-market is significantly reduced compared to three native teams.
One team instead of three
Flutter developers cover all platforms. Less coordination effort, simpler recruiting, lower personnel costs.
Pilot Phase
Deliver first, then commit. That's what the pilot is for.
- Duration
4-12 weeks
- Assessment
What core features does the app have? Which platforms (iOS, Android, Web) are relevant? What backend connections are needed? What platform-specific requirements (camera, push, offline) are there?
- Derived from this
Feature scope, architecture, backend strategy
Deliverables
- Implementation of up to 3 screens
with navigation and state management
- Up to 3 dynamic functions
e.g. form, list, filtering, detail view
- Backend connection optionally standalone
simplified setup of auth and database with up to 3 tables or connection of up to 3 endpoints of an existing backend
- Tested and deployed as a non-public preview
for any selection from: iOS, Android, Web
Frequently Asked Questions
FAQ
[] Why Flutter and not React Native?
Flutter compiles to native code – no JavaScript bridge, better performance, more consistent rendering. The ecosystem is growing rapidly, Google supports it, and the developer experience is the best in the cross-platform space. For most use cases, Flutter is the more efficient choice.
[] Does a Flutter app feel native?
Yes. Flutter uses its own rendering engine instead of platform-specific UI components – this gives you full control over pixel-perfect design. At the same time, platform-specific patterns (Material Design on Android, Cupertino on iOS) can be implemented if desired.
[] Can we migrate an existing native app to Flutter?
Yes, gradually. Flutter can be embedded as a module in existing iOS/Android apps. New features in Flutter, old ones remain native – until the migration is complete. The same logic applies to our frontend migration: parallel operation instead of big bang.
[] What about platform-specific features like camera or Bluetooth?
Flutter has a plugin ecosystem for practically everything – camera, GPS, Bluetooth, biometrics, push notifications. For special cases, we write platform channels that address native Swift/Kotlin code. In the assessment, we clarify what works out-of-the-box and what needs custom solutions.
[] How does the app get into the stores?
In the pilot, we deploy via TestFlight (iOS) and internal APK release (Android). In scale, we build a CI/CD pipeline that automates building, testing, and preparing for store submission. We accompany the review process at Apple and Google.
[] What is the pilot phase?
A clearly defined project with a defined scope – typically 4-12 weeks (depending on the use case). You won't receive a concept paper at the end, but a functioning result: real code, tested and deployed. The pilot shows you what we can do before you make a long-term decision.
[] What happens after the pilot phase?
After the pilot comes the proof: We look together at the results – what worked, what was worthwhile, where are the gaps? Everything measured against defined KPIs, not gut feeling. Based on this, you decide: scale, adjust, or stop. No pressure, no upselling. If the proof convinces, we move into scale – your project grows, your team grows with it, the knowledge stays with you.
[] Do I have to start with a pilot phase?
No. The pilot is our recommended entry point because it creates clarity for both sides – but it's not a must. If you already know what you need and want to get started right away, we can also join an ongoing project or start directly with a larger scope. We adapt to your pace.
[] Do you work T&M or fixed price?
Start as a timeboxed pilot in T&M (optionally with cap). No fixed price risk, no lock-in. You see at any time what you are paying for – and can stop at any time. But very few do.
