Mobile apps

iOS and Android apps from one codebase, native-feeling, shipped to both stores.

01 / The problem

Off-the-shelf isn't built for you.

Building separate iOS and Android apps doubles the cost and the bugs. Going fully native triples the timeline. We build with React Native so you get one maintainable codebase that feels native on both platforms, and we handle the unglamorous parts: store submissions, builds, and updates.

02 / Our approach

Three principles.
No exceptions.

01

One codebase

iOS and Android from a single codebase, so a fix or feature ships to both at once.

02

Native where it counts

Smooth gestures, notifications, and device features, it should feel like an app, not a web page in a wrapper.

03

Store-to-store handled

We deal with provisioning, review, and releases so you don't have to learn two consoles.

04 / Deliverables

What you get.
In writing, by week one.

iOS + Android app

A published app on both stores from one codebase.

Backend + API

The data, auth, and APIs the app runs on.

Store submission

Listings, assets, and the review process handled end to end.

Updates + support

Over-the-air updates and support after launch.

06 / Questions

The honest answers.

Yes, from a single codebase, so features and fixes ship to both at once.

Yes. We use native gestures, notifications, and device features; it shouldn't feel like a website in a wrapper.

End to end, provisioning, listings, review, and updates.
