A mobile app your customers want to reopen.
A mobile app lives in a pocket · it has to be fast, stable, and work on the subway. We ship it to the App Store and Google Play and get it past review on the first try.
Demo: pseudo-device · production: native iOS / Android (Swift / Kotlin) · App Store + Play release.
What we solve
- Slow and laggy · it doesn't feel like a real app
- Crashes when there's no wifi
- App Store rejects it on the first submission
- You don't know what users are actually doing inside
What we ship
- An app that feels fast and looks professional
- Works offline, syncs when the connection comes back
- Ready-to-ship store listings
- Clear data: who uses what, how often

Stack decision
Native vs RN · decided from business requirements, OS-feature needs, and the team. Not ideology, a decision.
- 0202 / 04
Architecture + offline
Data layer, sync strategy, conflict resolution, secure storage. This is what shapes your bug backlog two years from now.
- 0303 / 04
Build + user testing
Iterative build, internal TestFlight / internal track, real user testing. Not just the golden path.
- 0404 / 04
Store launch + ASO
Screenshots, keyword research, listing, review. Post-launch: remote-config-driven release management.
Common questions
What most people ask · answered before you have to.
Depends. Speed and a single codebase is priority → RN. Native OS features, maximum perf, minimize long-term tech debt → native. Let's talk about yours.
All main app features work without a network. Local edits, sync when back online, defined conflict resolution. Not 'we cache a bit'.
Yes. Keyword research, screenshot composition, listing copy, and first-review rejection recovery are on us.
Yes. Node.js / Go / Python + Postgres + Redis. Or we integrate if you already have one.
Most apps land €25,000-€70,000 depending on features and backend scope. Fixed price after a free scoping call, with fortnightly demos so you see real builds every two weeks.
Yes. We audit the codebase, the crash rate and the store standing, then stabilise and extend it. If the old code can't be saved we say so plainly and price the rebuild honestly.
End to end. Store listing, screenshots, privacy labels, review responses and the EAS build pipeline · we get it live and into TestFlight / internal testing, not just compiled.
