We agree scope, users and what the first shippable release contains.
-
Design
Architecture, navigation and API contracts settled before building.
-
Build
Iterative development with review at the end of each slice.
-
Verify
Device, performance and accessibility testing before release.
-
Release
Store submission, monitoring and post-launch support.

FAQs
Frequently Asked Questions
The questions we are asked most often about Android App Development.
Native when you need deep platform integration, best-in-class performance or heavy device feature use - camera, sensors, background work. Cross-platform when you need both platforms on one budget and the app is largely content and forms. We build both and will tell you which your requirements point to.
Your analytics answer this, not a rule of thumb. Supporting back to a version that covers roughly 95% of your actual users is typical; each extra year back adds testing cost and constrains which APIs you can use. If you have no data yet, we start with the current minus three major versions.
With a local database as the source of truth for the UI and a sync layer that reconciles with the server. The hard part is conflict resolution - what happens when the same record changed in both places - and that is a product decision we agree with you rather than defaulting to last-write-wins.
Yes, including the listing, assets, data-safety declarations and staged rollout. Google review is usually quick but data-safety and permissions declarations are where rejections happen; we prepare those properly rather than discovering the problem at submission.
