React Native apps for iOS and Android at once
We build cross-platform mobile apps with React Native and Expo - one JavaScript codebase, native performance where it matters, and over-the-air updates that skip app store review cycles.
Trusted by companies that ship production software on deadline
Everything you need, nothing you don't
We scope each engagement precisely so you get senior-level work on the capabilities that matter.
Shared business logic
One TypeScript codebase for authentication, API calls, state management, and validation - ship features once, deploy everywhere.
Native modules
Bridge to platform-specific APIs when JavaScript isn't enough - camera, payments, biometrics, and third-party SDKs.
OTA updates
Push JavaScript bundle updates instantly via Expo or CodePush - fix bugs and ship features without waiting for store approval.
Hot reload
Fast Refresh preserves component state while you edit - see UI changes in the simulator within milliseconds.
Code Push
Microsoft App Center integration for staged rollouts and rollback - control who gets which update and when.
Shared testing
One Detox or Maestro test suite runs against both platforms - catch regressions before they reach TestFlight or internal tracks.
From React Native scaffold to dual-platform launch
We deliver Expo or bare-workflow builds for both platforms every sprint - so your team validates iOS and Android in parallel from week one.

Launch: Store submission & OTA pipeline
We submit to both app stores, configure CodePush or Expo Updates, and set up CI/CD for automated builds and releases.
Renting is local, so search had to understand a place and a date range as one question rather than two filters. Mirimera built the marketplace and the software our suppliers run on, and because it is one system underneath, nothing has ever had to be kept in sync.
