## one codebase or two apps?

_TECHNOLOGY_

There's no single right answer. We choose per project and tell you why up front.

<https://oxarus.com/en/studio/mobile#stack-heading>

- **Single codebase**
  - **tech:** React Native · Expo
  - **source:** Two apps from one source
  **When it fits**
  - When the app and web will evolve together
  - When the first release needs to ship fast
  - When most screens are lists, forms and content
  > The right starting point for most business apps.
  - Scanner.tsx
  - app.json
  - **Shared code**
    85–95%
  - **First release**
    8–12 weeks
  - **Device access**
    Via modules
  - **Workflow**
    One workflow
- **Separate native apps**
  - **tech:** Swift · Kotlin
  - **source:** Each platform from its own source
  **When it fits**
  - When camera, audio or sensors are used heavily
  - When widgets and watch apps matter
  - When interaction is graphics-heavy or game-like
  > For projects that need the deepest device access.
  - ScanView.swift
  - ScanActivity.kt
  - **Shared code**
    0–20%
  - **First release**
    14–20 weeks
  - **Device access**
    Full
