Mobile apps

iOS and Android from one codebase — or a PWA when no store is needed.

Cross-platform by default: one React Native codebase covers both platforms and shares code with the web. Native modules go in where the task genuinely hits the platform — background location, peripherals, permission-specific behaviour. The third option gets said out loud because it is often the right one: if the app is only for your own customers and never has to pass store review, a PWA is cheaper and updates the moment you deploy.

What the work covers

A React Native app covering iOS and Android from one codebase
PWA: home-screen install, offline mode, push where the platform allows it
Release builds and signing, CI setup, store submission to App Store and Google Play under your own developer accounts — the app stays yours after the engagement ends
Integration with your backend — or building the API for the app if there is no backend yet
Offline storage and sync: the app keeps working underground and in a warehouse
Every screen state: loading, empty, error, offline — not only the happy path

Who this fits

A fit: the scenario repeats — the app gets opened regularly, not once a year before a holiday
A fit: you need camera, location, offline, push — the things the web gives you badly or not at all
A fit: a web product already exists and part of its logic and API can be reused instead of built twice
Not a fit: an app that is a second website — the same content in a wrapper. App Store review objects to exactly that under Guideline 4.2 (minimum functionality)
Not a fit: the budget covers one platform but you need both — starting with a PWA and returning to the stores later is the honest route
Not a fit: the launch date is tied to an event. Release goes through store review, whose timing is not mine to control

What moves the price

One platform or both, and how strictly each platform's guidelines must be honoured rather than showing the same screen twice
Offline: whether the app merely caches data or has to resolve sync conflicts
Whether an API already exists. With no backend, it becomes a separate — and usually larger — part of the estimate
Push, in-app payments, maps, biometrics: each subsystem is priced on its own
Design: you supply the mockups, or screens are designed from scratch, including states and both platforms' conventions
Store preparation: privacy policy, data-collection declaration, age rating, screenshots

What you keep

Sources in your repository; signing certificates and keys on your own Apple and Google accounts
CI configured so a release build runs without me
Builds in TestFlight and the Google Play internal track before any user sees the app
Store listing material: description, screenshots, data-collection declaration, privacy policy
A written list of what the next major iOS or Android release will break, and what to do about it
