React Native Development Agency
Senior React Native + Expo — production iOS and Android, EAS builds, stores, fixed price.
React Native only works when someone has shipped it through store review, Android edge cases, and push. Junior-only teams ship crash loops; we treat device QA as part of delivery.
Expo is the default: faster builds, OTA where allowed, less native yak-shaving. We go bare React Native when a module forces it — and we tell you that before kickoff, not in week four.
Timeline: 21 daysPrice: From $3,460Fixed price — no hourly billing
Why react native development is easy to get wrong
Junior RN apps that crash on specific Android OEMs
Wrong Expo vs bare decision that costs a rewrite
Push, deep links, and store listing treated as afterthoughts
What we build
Expo apps
EAS Build, profiles, and a release process you can keep.
Native modules when needed
We do not fight Expo if a vendor SDK requires ejecting — we plan it.
API + app together
The mobile client is not an orphan. Backend is in the same delivery.
Typical features in v1
TypeScript end to end
Same language as our Next.js web work.
Store pipeline
TestFlight, internal testing tracks, and review notes.

FAQ
Why an agency instead of a RN freelancer?
Coverage, iOS + Android QA, store submission, and a fixed price. One person on vacation should not freeze your launch.
Do you use Expo?
Yes for most projects. Bare RN when a native SDK requires it.
Flutter instead?
Read our React Native vs Flutter guide. We default RN when the rest of your stack is TypeScript.
