iOS + Android, built once
Feels native, costs less.
Real gestures, smooth transitions, the right haptics. React Native where it's smart, a drop to Swift or Kotlin where the app actually needs it.
mobile apps
iOS and Android, one team.
The app your users keep on their home screen. Designed and built by one small team, from first sketch to both stores — without paying to build everything twice.
what you get
Both stores, one codebase
We build with React Native, so iOS and Android come from the same source. One team, one budget, two stores.
On your phone every Friday.
A TestFlight build each week. You use the real thing in your pocket, not screenshots in a deck.
Yours forever.
Code, design files, and the store listings sit in your accounts. No lock-in if you grow past us.
The whole phone.
Push, camera, maps, biometrics, offline. The device features that make an app worth installing, wired in properly.
Updates without the wait.
Over-the-air updates push fixes and tweaks straight to phones, so small changes don't mean another store review.
how it works
Three phases. No black box.
Short, visible loops. The app lives on your phone the whole way, so you always know where it stands.
- 01scope & sketch
Discover. Paid, two weeks.
We unpack the problem, lock the scope, and put a tappable prototype on a real phone — so we start from something you can feel, not a guess.
- 02design & build
Build in weekly slices.
Screens and flows shipped feature by feature. A TestFlight build every Friday — install it, use it on the bus, tell us what feels off.
- 03launch & grow
Ship both stores.
We handle App Store and Play Store submission, review, and the 30-day warranty. Keep us on monthly for updates that ship over the air.

Calaboca
A map-first app for discovering local hidden gems — the kind of thing that makes any city feel like an insider's tour. Designed, built, and shipped to the App Store.

the stack
Boring tech. Exciting apps.
Proven tools over trendy ones, so your app stays easy to run long after launch. This is our default — not a religion.
app layer
One codebase, both stores.
React Native and Expo, typed in TypeScript. Native modules where the app needs the metal.

backend & data
Sync that just works.
A typed API and Postgres behind the app, with offline-first data so it stays useful without signal.

Everything the phone can do.
Push, camera, maps, biometrics, payments — through SDKs that have already handled the edge cases.

ship & stores
Submission, sorted.
TestFlight, store listings, review, and over-the-air updates. We handle the parts that make first-timers groan.
