The problem
The cross-platform shortcut usually shows. Janky scroll, half-baked offline, push notifications that arrive in the wrong language, an app store rejection two days before launch.
Done right, the seam disappears. One team, one codebase, two stores — with the polish people associate with Swift and Kotlin. We pick the boring path that gets you there.
What “native-feel” actually means.
In rough order of how often it gets skipped.
60fps scroll, every list
FlashList, Reanimated 3, Skia where it earns its weight. Smooth on a 5-year-old Android.
Offline-first data
WatermelonDB, MMKV, optimistic UI. The app works on the subway, syncs when it lands.
Push that doesn’t embarrass you
OneSignal or Expo Notifications, with proper i18n, deep linking, and background handling.
Auth + biometrics
Sign in with Apple, Google, biometric unlock. Token rotation, secure storage, no surprises.
In-app purchases & paywalls
RevenueCat. Plans, trials, restores, family sharing — the things Apple’s reviewers will check.
Crash-free release pipeline
EAS builds, OTA updates, Sentry, store submission automation. Ship in hours, not weeks.
What you get, shipped.
Concrete artifacts, not slide decks. Every engagement ends with these in your repo, your cloud, your hands.
Production app, both stores
iOS + Android, signed, submitted, with screenshots and metadata.
EAS build pipeline
Internal, beta, and production tracks. OTA updates configured.
Offline-first data layer
Local-first DB, sync engine, conflict resolution, queueing.
Push notification system
Server hooks, deep links, locale-aware payloads, opt-in flows.
Crash + performance dashboard
Sentry + Firebase Performance. Alerts on regression.
Store assets
Icons, screenshots, App Store / Play Store copy in your locales.
Eight to twelve weeks to both stores.
Foundation
Architecture, auth, navigation, data layer, design tokens. The app skeleton.
Core flows
The 5–7 screens users will live in. Offline, gestures, polish.
Polish & ops
Push, IAP, deep links, crash reporting, perf budgets.
Submit & ship
Beta with TestFlight + Play internal, fix the inevitable rejection, launch.
Tools we reach for, by default.
Not religious about any of these — we'll use what your team can maintain after we leave.
Other things we build.
Most engagements blend two or three of these. If you're not sure where your project fits, send us a brief and we'll suggest the right slice.
Web platforms
Marketing sites, dashboards, portals, content systems. Built for speed, accessibility, and edit-ability by your team.
Product engineering
SaaS, MVPs, internal tools — typed APIs, real-time data, auth, billing, observability.
Design systems
Tokens, components, Figma kits — versioned, themable, generated from one source of truth.
One codebase. Both stores.
