React Native in India: when one codebase is the right call
One team, two platforms — provided you know which parts will not be shared.
React Native suits business apps built from forms, lists, media and payments — most of what Indian companies need. It saves roughly thirty to forty percent of the effort of building twice. It is the wrong choice for apps that lean heavily on hardware, background processing or platform-specific interaction.
Key takeaways
- Expect to save thirty to forty percent of the effort of two native builds, not fifty.
- Some code always stays platform-specific — plan for it rather than discovering it.
- Over-the-air updates change your release cadence more than the framework choice does.
- Test on a mid-range Android throughout, not at the end.
The pitch for React Native is one codebase and half the cost. The honest version is one codebase, most of the time, and about a third off — which is still a very good deal for the kind of app most businesses need.
Where it clearly wins
- Apps built from forms, lists, detail screens, media and payments — the shape of most business apps.
- Teams that already write TypeScript and React on the web, so one group can maintain both.
- Products that need a fortnightly release cadence, especially with over-the-air updates for JavaScript-only changes.
- Startups where the same engineers have to cover web and mobile without a second hiring round.
Where it does not
- Heavy camera, audio or sensor work where every millisecond and every platform quirk matters.
- Background processing with strict OS constraints — location tracking, long-running sync.
- Apps whose value is a platform-specific interaction that must feel exactly native.
- Anything expected to run acceptably on very old, very low-memory Android devices.
Over-the-air updates
With Expo, JavaScript-only changes can be pushed without a store review. A bug found on Monday morning is fixed by Monday afternoon rather than in three days. Native changes still need a store release, so the discipline is to know which of the two you are shipping.
Cost and timeline in India
| Approach | Timeline | Ongoing cost |
|---|---|---|
| React Native, both platforms | 3–4 months | One codebase, one upgrade cycle |
| Native iOS only | 3–4 months | One platform to maintain |
| Native, both platforms | 4–6 months | Two codebases, two teams, two release cycles |
The maintenance difference matters more than the build difference, and it is the column people leave out of the comparison. Two native codebases is two upgrade cycles, two sets of dependency updates and two teams on call, every year, for as long as the app exists.
