Matrix Console Android
A neutral Android client showcasing Matrix capabilities and implementation.
Not actively maintained
Matrix.org’s reference Android client.
This client is meant to be a showcase of Matrix capabilities, a reference implementation of the Matrix standard and an easy entry to the Matrix ecosystem from Android devices for less techy users, with a relatively neutral branding.
The code can be retrieved from github.
Also available from the Google Play store.
Folks wanting to live on the bleeding edge can also pull APKs of the develop (and master) branches straight out of the Jenkins build server.
