How to read this catalogue

The rules this site applies to itself.

Status means something

Released means the build is finished. It does not mean a store listing exists — that is a separate state, and the site refuses to build if the two are mixed up.

Screenshots are real

Every image labelled a screenshot came out of the running software. Where a project has none, it says so rather than showing artwork that could be mistaken for one.

Nothing is on Google Play yet

No download or store button appears anywhere, because no listing exists to link to. When one does, the button appears by itself.

Claims trace to evidence

Versions, permissions, minimum Android versions and technology lists were read out of each project’s own build files.
