Who it's for.

- Founders launching a mobile-first consumer product
- Businesses that need a reliable app for staff or customers on both platforms
Things we could build for you.
Companion app
A mobile version of your web product so customers can check, reply and act on the go.
Field team app
An app for staff on site to log jobs, take photos and sync when they are back online.
Consumer subscription app
A habit, fitness or learning app with onboarding, reminders and in-app subscriptions.
What you get.
- 01
Mobile UX design
Screens and flows designed for thumbs and small screens, following iOS and Android conventions.
- 02
Cross-platform app
One React Native and Expo codebase that runs natively on iPhone and Android.
- 03
Backend and sync
APIs, auth and data sync, including offline support where your users need it.
- 04
Push notifications
Targeted notifications and deep links that bring users back to the right screen.
- 05
Store release
Builds, signing, store listings and review submission for the App Store and Google Play.

Over-the-air updates
Fixes and small changes shipped to users without waiting for a full store review.
How we'll build it.
Step 1
Pick the core screens
We decide what belongs in the app versus the web, and plan milestones around the key mobile flows.
Step 2
Design for the phone
Clickable mobile designs reviewed with you before any code, so flows feel right in the hand.
Step 3
Weekly test builds
Every week you install a new build on your own phone and see real progress.
Step 4
Submit and release
We prepare store assets, submit for review and set up over-the-air updates for after launch.
What usually goes wrong, and what we do instead.
- 01
Building separate iOS and Android apps doubles the time and the bugs.
We build one React Native codebase that ships to both stores and keeps features in sync.
- 02
App store reviews and release builds feel like a black box.
We set up builds, signing and store listings, and handle the submission process with you.
- 03
Your web product and mobile app drift apart.
We share types and backend logic with your web app, so both read the same data the same way.
