Works without a signal
A local-first data layer with a sync path, so a user in a basement or a warehouse keeps working and the queue reconciles when the connection returns.
Product Engineering — How it ships
App Development
Mobile products that behave on a weak connection and stay on the first screen.
- React Native & native builds
- Offline-first architectures
- Store release and maintenance
- Engagement shape
- Prototype phase, then a fixed-scope build, then a maintenance retainer covering platform updates.
- Typical duration
- Eight to sixteen weeks to first release.
- Starting point
- The single flow the product lives or dies on.
Overview
What the work involves.
Phone software is judged in the first thirty seconds and in the worst network conditions your users meet. Cold start, offline behaviour and download size decide retention far more often than the feature list does.
We build with React Native where one codebase can serve both stores properly, and go native where the product leans on a platform capability that deserves it — background location, heavy camera work, a widget people open every day.
Release is part of the build rather than a phase afterwards. Store metadata, staged rollout, crash reporting and an over-the-air update path for the fixes that cannot wait for a review queue.
Outcomes
What you get.
A cold start that holds attention
Startup time, bundle size and time to first interaction measured on mid-range devices and treated as a release gate.
Both stores, one team
A shared codebase and a single release process, with native modules written only where the platform genuinely requires them.
Crashes you hear about first
Crash and performance reporting from day one, grouped by release, so a regression is caught before the store reviews arrive.
Deliverables
What lands in your hands.
- iOS and Android builds from a shared codebase
- Offline-first data layer with conflict handling
- Push notification and deep link setup
- Authentication and secure credential storage
- Crash, performance and analytics instrumentation
- Store listings, screenshots and release submission
- Over-the-air update pipeline for urgent fixes
Approach
How we run it.
Prototype the risky screen
The flow with the hardest interaction or the worst network case is built on a real device first, before the rest of the product is scoped.
Build the data layer
Local store, sync rules and conflict resolution early, because retrofitting offline support into a networked app is close to a rewrite.
Feature slices on device
Every slice tested on mid-range hardware rather than only a simulator, with startup and interaction cost checked per release candidate.
Release and watch
Staged rollout, crash monitoring and a fast patch path, with the first update planned before launch instead of after the reviews.
Each phase ends with something you can read and act on. If the evidence says stop, stopping there is a supported outcome rather than an awkward conversation.
Stack
What we build it with.
- React Native
- Expo
- TypeScript
- Swift
- Kotlin
- SQLite
- Firebase
- Sentry
Tooling is a decision we make per project, against your constraints and whatever your team already runs. Nothing on this list is a requirement, and we will work inside your existing stack where it holds up.
Questions
What clients ask about App Development.
React Native for most products, because one team ships both stores and the gap in feel is now small. Native where the app leans on background processing, heavy camera work or platform widgets, sometimes as a native module inside a React Native app.
Yes, including listings, screenshots, privacy declarations and the review correspondence. Rejections are usually about metadata rather than code, and we deal with them.
A maintenance arrangement covering operating system updates, dependency upgrades, crash triage and store policy changes, all of which arrive whether or not the product is changing.
