# Mobile app development

An app is the visible tenth of the product. We build all of it from one codebase: the screens, the backend it syncs with, the push notifications, and the store submissions. One team, no gaps between layers.

## Problems clients bring us

- **Two codebases, twice the bugs.** An iOS dev, an Android dev, and features that never quite match between them, each fix paid for twice.
- **The backend was an afterthought.** The app looked done, until login, sync, and push notifications needed a server nobody scoped or priced.
- **Stuck in review limbo.** Rejected twice by the App Store for things your developer insisted were fine. Launch day keeps moving.
- **v1 shipped, then silence.** The store listing still says “bug fixes and improvements.” The bugs are still there. The developer isn't.
