Mobile apps that feel right in the hand.
We design and build cross-platform apps for iOS and Android from a single codebase, from real-time multiplayer to offline-first tools. We've taken OneOfUs through both app stores in ten languages, so we know the whole road from build to launch.
Build a mobile app, done properly.
- 01
One codebase, two stores
iOS and Android built together with Flutter or React Native, so features ship to everyone at once.
- 02
An app that feels native
Smooth animations, platform conventions and thoughtful details users notice, without doubling the cost.
- 03
A launch without surprises
App Store and Google Play submission, review guidelines, in-app purchases and release management handled.
Where this service shines.
A few of the kinds of projects we take on. Not seeing yours? Tell us about it anyway.
- Consumer & social apps
- Real-time & multiplayer experiences
- Companion apps for SaaS products
- Booking & ordering apps
- Field & operations tools
- Subscriptions & in-app purchases
How we'll get you there.
Every engagement follows the same rhythm: working software early, a demo every week and no surprises.
- 01
Prototype the experience
Clickable prototypes on real phones early, so we get the feel right before writing production code.
- 02
Build the foundations
Auth, data sync, notifications and analytics set up properly from the start.
- 03
Test on real devices
Weekly builds on TestFlight and internal testing tracks, so you're using the app as it grows.
- 04
Ship to the stores
Store listings, screenshots, localisation and submission, then updates on a steady cadence.
We've shipped our own app to both stores.
OneOfUs is our own product, designed, built and run by the same team that would build yours.

Flutter or React Native?
Both are excellent. We recommend one based on your team, existing code and the experience you need, and we'll explain the trade-offs in plain English.
Do you handle App Store and Google Play submission?
Yes. We prepare listings, handle review requirements and manage releases, including in-app purchases and subscriptions.
Can the app share a backend with our website?
Usually, yes. We design APIs so your web app, mobile app and admin tools all work from the same data.
