The approach

How we think about app development

Shipping an app is the easy half. We scope ruthlessly for a first release that proves value, build on a maintainable stack, handle the review and compliance process for both stores, and then treat installs, activation and retention as marketing problems — because they are.

Common questions

Native or cross-platform?

Cross-platform for most content and commerce apps; native when you depend on heavy device hardware, background processing or platform-specific UX.

Do you maintain the app after launch?

Yes. Monthly maintenance covers OS updates, store policy changes, bug fixes and a shared feature roadmap.
