One codebase.Two stores. No fiction.
Cross-platform saves real money on screens, lists and forms. It saves nothing on store listings, permissions, push certificates or review. We scope both halves so the saving is a number rather than a hope.

In short
Byteinfy builds cross-platform mobile apps from $6,000 in React Native or Flutter, one codebase shipping to the App Store and Google Play, with the platform-specific work called out in the scope rather than discovered at submission.

Who it is for
- Products that need iOS and Android at the same time on one budget
- Web teams with React skills who want to own the app afterwards
- Businesses replacing a field process that runs on WhatsApp and paper
- Founders validating a mobile idea before committing to native
What you get
- React Native or Flutter app targeting iOS and Android from one codebase
- Platform-correct navigation and components, so neither store's users feel they got the other one's app
- Offline support and background sync where the workflow needs it
- Both store listings: App Store Connect and Play Console, with data safety and privacy forms
- Over-the-air update channel so copy and logic fixes ship without a review cycle
- CI that produces installable builds for both platforms on every merge
How it works
- 1
Scope
We separate shared work from per-platform work and price them apart, so you can see what cross-platform is actually saving.
- 2
Build
Weekly builds on TestFlight and the Play internal track, on your own devices.
- 3
Ship
Both submissions handled, staged rollout on Play and phased release on iOS.
Pricing
From $6,000
iOS and Android from one codebase starts at $6,000 — less than two native builds, more than one, because both stores still have to be satisfied separately.
Questions we get asked
- React Native or Flutter?
- React Native if your team writes JavaScript or React, or the app shares logic with a web product. Flutter if the UI is heavily custom and identical on both platforms. Either is a defensible choice; the wrong one is the one nobody on your side can maintain.
- Is it really cheaper?
- For screens and business logic, yes — usually 30 to 40 percent against two native builds. Store work, permissions and device testing do not shrink, and we quote them separately so the comparison is honest.
- When should we go native instead?
- Heavy graphics, tight hardware integration, or a platform API released this year. We say so before you spend rather than after.
