how we work

You install it on your phone long before launch.

Wireframes and a data model come first, so every screen has a clear job. After that, every milestone ships a build you can test on real devices.

What Google Play requires of an app.

The standards and published guidance behind how we deliver this service, with every claim linked to its source.

01Target API requirements

Google Play requires new apps and updates to target a recent Android API level, and the minimum rises each year [1]. Keeping an app publishable is ongoing work.

KEY FACTApps that fall behind the target API requirement can’t publish updates on Google Play [1].

02Quality and stability

Android’s core app quality guidelines set expectations for visual design, functionality and performance [2]. Android vitals tracks crash and ANR rates, and poor rates can reduce an app’s visibility on Google Play [3].
