Offline-first income and expense tracker for Android and iOS. My own product, live on both stores.
Service 02 / 05
Mobile Apps
React Native apps for iOS and Android that work offline and ship to the stores.
Cross-platform iOS and Android apps in React Native — offline-first data, push notifications, deep links, and a store release handled end to end, backed by an API designed for mobile.
A good mobile app is mostly invisible engineering: local-first data that survives bad networks, sync that resolves conflicts, push that arrives, and links that open the right screen.
I build the app and the backend it talks to, so the API, auth, and notification pipeline are designed for mobile from the start — then take the app through TestFlight, Play Console, and store review.

Process
How we work
- Step 1
Discovery
A working session on goals, users, constraints, and existing systems. You get a written scope, open questions, and a clear recommendation on what to build first.
- Step 2
Architecture
Data model, service boundaries, auth, async work, and infrastructure are designed up front and shared as a short architecture document before any code is written.
- Step 3
Build
Milestone-based delivery with a staging environment from week one, regular demos, and code in your repository — not a black box handed over at the end.
- Step 4
Launch
Production deployment with CI/CD, monitoring, backups, and a rollback path. Launch is rehearsed on staging so release day is uneventful.
- Step 5
Support
Post-launch stabilisation, then an optional monthly retainer for features, upgrades, and on-call fixes. Handover docs are included either way.

FAQ
Common questions
Something else? Ask directly.
Why React Native instead of separate native apps?
One TypeScript codebase ships to both iOS and Android, which roughly halves build and maintenance effort for most business apps. Native modules are added where a feature genuinely needs platform-specific code.
Can the app work without an internet connection?
Yes. Offline-first apps store data locally and sync in the background when the connection returns, with conflict handling designed around how your users actually work.
Do you handle App Store and Google Play submission?
Yes — builds, store listings, review submissions, and responding to review feedback. Apps are published under your own developer accounts so you keep full ownership.
Do you also build the backend for the app?
Usually, yes. Auth, push notifications, sync, and payments work best when the API is designed for mobile from the start. I can also integrate with an existing backend.
How are updates shipped after launch?
JavaScript-level fixes can ship over the air without a store review; native changes go through a normal store release. Both are covered under an optional monthly retainer.
