How this works
01
Feature lock
We map every screen and user flow against the chosen package. Anything not in the package is identified before we begin — not discovered mid-sprint.
02
UI design sprint
Screen-by-screen designs in Figma — reviewed and approved on mobile viewports. No development begins until design is signed off.
03
Build & test cycles
Development in 2-week sprints with TestFlight/Play Store builds at each cycle. You test on a real device. Feedback tracked; scope changes priced.
04
Store submission (Pro)
Metadata preparation, screenshot production, submission to App Store Review and Google Play review queue.

Questions about this service Mobile App Development
Do you build for both iOS and Android?▼
Yes — one React Native codebase delivers both platforms. Both platforms are included in every tier from Starter up.
What is the feature lock process?▼
Before development starts, we map every screen and user flow against the chosen package. Features not in scope are identified before the first sprint — not mid-project.
Do you handle App Store and Google Play submission?▼
App store submission is included in the Pro tier. This includes metadata, screenshots, and support through the review process. Starter tier delivers TestFlight and internal Play Store builds.
Can you connect to our existing backend?▼
Yes. REST API integration with your existing backend is included in both Starter and Pro. If you need a new backend, we scope that as a separate service.
