Native and cross-platform apps,
crafted.

iOS, Android, React Native — one senior team handling design, motion, offline-first state, and a design language that travels across both stores.

Apps that feel native, even when they aren't.

We pick the right tech for your audience — Swift, Kotlin, React Native or Expo — and treat motion, haptics and gestures as design primitives.

  • Motion-led design

    Spring-based motion, haptics on the right moments, transitions that explain hierarchy. Designed in Origami, shipped in Reanimated or SwiftUI.

  • Right tool, right platform

    Native Swift / Kotlin when the app earns it. React Native + Expo when it doesn't. We'll be honest about which one is right for you.

  • Offline-first state

    Optimistic UI, queued mutations, conflict resolution. Your app works in airplane mode and on subway WiFi.

  • Design once, ship to both

    A single component library that translates faithfully to iOS and Android idioms — not the lowest common denominator.

  • App store-ready

    Submission, metadata, screenshots, ASO. We've shipped apps to both stores 14 times; we know where the landmines are.

  • Instrumented from day one

    Amplitude or PostHog for behaviour, Sentry for crashes, RevenueCat for subs. Your data team gets a working pipeline.

Twelve weeks to a shipped app.

Discovery, prototype, build, store submission — paced for quality, not just speed.

01
Discovery & UX research
Five user interviews, competitor teardown, hardware audit. We learn what your users actually do on their phone.
+
02
Motion prototype
A clickable, motion-correct prototype in Origami or Principle. Real spring animations, real haptics — before any code.
+
03
Build sprint 1 — primitives
Auth, core nav, design system, persistence. The boring layer your future engineers won't have to rebuild.
+
04
Build sprint 2 — the core loop
The one thing your app is for. Designed, built, tested on real devices in your users' hands.
+
05
Polish & motion pass
60fps everything, haptics tuned, empty / loading / error states designed. The polish that decides 4-star vs 5-star.
+
06
Store submission & launch
App Store + Play Store submissions, ASO copy, screenshots, video preview. We sit through the review with you.

Tools that travel across both stores.

Some apps deserve native. Some don't. We'll recommend honestly on the intro call.

Everything you walk away with.

Documented, handed off and ours to defend. We don't believe in deliverables that need our help to use.

  • 01
    Shipped app on both stores
    iOS + Android, submitted, approved, live. Or one store with a clear plan for the other.
  • 02
    Motion + design system
    Documented spring values, haptic patterns and components — your future designer can extend without re-inventing.
  • 03
    Production codebase
    Whether native or React Native, fully documented, MIT-licensed and CI/CD-ready.
  • 04
    Backend (if needed)
    Supabase or custom Postgres + edge functions, auth, push notifications, schedulers.
  • 05
    Store assets & ASO
    Screenshots, video preview, descriptions and keyword research for both stores.
  • 06
    30-day post-launch sprint
    Crash triage, rating monitoring, ASO tuning. We don't leave until you've crossed 4.5 stars.

Questions, answered plainly.

Still unsure? Email a partner — replies within 24h.

Native or React Native?
Depends on the app. Heavy animation, sensors, AR, or platform-specific UX → native. CRUD-style apps with parity across platforms → React Native + Expo. We'll be honest on the intro.
Do you handle the store submission?
Yes — including the back-and-forth with reviewers, screenshots, ASO copy, and the inevitable rejection-and-resubmit cycle.
Can you take over an existing React Native app?
Often, yes. We've rescued three React Native apps in the last two years. We'll audit and propose a salvage plan before committing.
What about a web companion?
We've shipped many app + web companion combos. A unified design system that travels across both is one of our favourite problems to solve.

Often shipped together.

Brand, product and growth compound when they ship under one roof. Here's what pairs best with Mobile App Development.
