Cross-platform app development

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.

Last updated 8 September 2026 · Written by the Byteinfy team, which builds and operates SwipeReel and myBillPlease.

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. 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. 2

    Build

    Weekly builds on TestFlight and the Play internal track, on your own devices.

  3. 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.
