Cross-platform app
React Native or Flutter: one codebase for iOS and Android — usually noticeably cheaper and faster than two native apps.
Updated
One app for iOS and Android from a single React Native or Flutter codebase — usually faster and cheaper than building two native apps. Timeline: 14+ calendar days. Priced after a short brief.
What's included
- React Native or Flutter pick
- One codebase for both platforms
- Native modules where speed matters
- Both stores covered
- Over-the-air code updates where store rules allow
Most business apps don't need two separate native codebases. Catalogs, bookings, accounts, delivery tracking, internal tools — these work well from one codebase in React Native or Flutter, which ships to both iOS and Android. You get one team, one set of features and releases on both platforms at the same time.
When it's not the right choice: heavy graphics and games, apps built around complex camera or AR processing, or products that depend on the newest platform APIs on day one. There, native iOS and native Android development pays off.
Who it's for
- Startups that need to launch on both platforms with one budget.
- Businesses adding an app to an existing website or CRM.
- Companies replacing an outdated app with a maintainable one.
- Teams that want a single codebase their own developers can pick up later.
How we work
- Discovery. We define the key scenarios and check whether any feature requires native code.
- Stack choice. React Native fits teams with web/JavaScript experience and apps close to standard UI; Flutter gives tight control over custom interfaces. We explain the trade-off for your case.
- Design and prototype. Screens that respect both iOS and Android conventions.
- Development. Shared code plus native modules where performance or device access needs them.
- Release. Builds, store listings and review for the App Store and Google Play.
What matters technically
Performance problems in cross-platform apps usually come from architecture, not the framework: long lists, heavy images, chatty network calls. We plan for them early. Over-the-air updates for JavaScript or Dart code can speed up fixes, but only within store rules — anything that changes the app's purpose still goes through review.
Timeline and cost
Development takes 14+ calendar days. Cost is estimated after a short brief and depends on the number of screens, the backend, integrations and native features.
Example
For example, for a fitness studio network: one app for clients on both platforms with a class schedule, booking, membership status and push reminders, connected to the studio's existing booking system.
What we need from you
Your core scenarios, existing designs or brand assets, access to the backend or APIs the app should use, and developer accounts in both stores. After launch, mobile app support keeps the app current with new OS releases and store policies.
