The Right Cross-Platform Framework for Your Team and Systems
React Native, Flutter and .NET MAUI can all ship one app to iOS and Android. The right choice depends on who will maintain it, what it connects to and how long it needs to last. We help you decide, then build or migrate on that framework.

When Cross-Platform Is the Right Call
Teams usually come to us with a framework decision to make or a migration that can no longer wait.
We recommend a framework, not a favorite.
The choice follows your existing team, systems and long-term maintenance needs. If native apps would suit you better, we will say so.
Two separate apps cost too much to maintain
Every feature is built twice for iOS and Android. Over time the two versions drift apart.
Your Xamarin app has reached end of support
Microsoft ended Xamarin support in May 2024. New OS versions and store rules make each release harder.
You're not sure which framework fits
React Native, Flutter and .NET MAUI all look viable. You want a recommendation based on your situation, not on hype.
Your team already works in .NET
Your backend and developers are on .NET, so a mobile stack in a different language adds hiring and handover risk.
Six Ways We Help Across Platforms
Pick one to see what it usually involves and how we typically build it.
React Native apps
A good fit when your web front end is React or your team knows TypeScript, so code and skills carry across web and mobile.
- Shared logic with React web apps
- Large library ecosystem
- Over-the-air updates for JavaScript changes
Flutter apps
A good fit when the app needs a highly customized look that stays consistent on every device and the team is open to Dart.
- Consistent UI on iOS and Android
- Custom design and animation
- One codebase for mobile
.NET MAUI apps
The natural fit when your backend and developers already work in C# and .NET, so one language runs from the database to the phone.
- Shared C# models and logic
- Mobile and desktop from one project
- Direct path from Xamarin
Xamarin migration
Moving Xamarin apps to .NET MAUI or React Native in stages, keeping the business logic that still works and releasing without disrupting users.
- Xamarin.Forms to .NET MAUI
- Xamarin to React Native
- Plugin and dependency replacement
Shared backend and API design
One backend that serves iOS, Android and web, so business rules live in one place and every client gets the same data.
- Authentication and roles
- Data and business logic APIs
- CRM and ERP integration
App store release and updates
Store submission, release pipelines and regular updates for new OS versions, store rules and features.
- App Store and Google Play submission
- Automated build and release
- OS and SDK upgrades
Decide First. Build Second.
Every engagement follows the same problem-first Systems Engineering Method we use across AppPotter.
Review your team and systems
We look at who will maintain the app, what it connects to and any existing code worth keeping.
Recommend a framework
You get a written recommendation with the trade-offs of each option for your situation.
Prove the risky parts
Device features, integrations or migration paths that could cause trouble are tested early in a small build.
Build or migrate in increments
You see working builds at agreed checkpoints. Migrations run in stages so the current app keeps working.
Test on real devices
Functional, performance and security checks across iOS and Android versions before release.
Release and maintain
Store submission, then regular updates as OS versions and store rules change.
What Changes When the Process Runs on the Right System
We agree on what to measure during discovery, so success is defined before the build starts, not after launch.
Before: Every feature built twice for iOS and Android
After: One codebase for both platforms
Before: A Xamarin app with no support path
After: An app on a supported, current framework
Before: A framework chosen on developer preference
After: A framework chosen for your team and systems
Before: Web and mobile teams working in different stacks
After: Shared skills and one backend across web and mobile
Before: Store releases handled ad hoc
After: A repeatable release process for every update
Chosen for Your Systems, Not Our Preferences
We work across React Native, Flutter and .NET MAUI, with .NET backends on Azure or AWS. We recommend the framework based on your existing team, systems and long-term maintenance, not on our preference.

Cross-Platform FAQs
Still unsure? A 30-minute conversation usually answers the rest.
Book a callIt depends on your team and systems. React Native suits teams already using React or TypeScript. Flutter suits apps that need a highly customized interface. .NET MAUI suits teams whose backend and developers are on .NET. We recommend one after reviewing your situation.
For most business apps, yes. Users get native controls and the performance they need. Native development can make sense for graphics-heavy apps or deep platform features and we will tell you if your app falls into that group.
Plan a migration. Microsoft ended Xamarin support in May 2024. .NET MAUI is the most direct path for Xamarin.Forms apps. React Native can make sense if your team is moving toward JavaScript.
Usually yes. We keep the business logic and backend code that still work, replace what is tied to Xamarin and migrate in stages.
Partly. React Native can share logic with a React web app and .NET MAUI can target desktop. We share code where it saves effort without forcing one app to fit every screen.
Framework assessments are usually short and fixed price. Builds and migrations can be fixed price with milestones when the scope is clear or run with a dedicated team when it is still evolving.
