To join the beta group you need to follow two simple steps
1. Join the following Google+ group
2. Become a tester using this page
After you become a tester you can press Install on the same page and Google will teleport the app to your device or download it the old fashioned way using the Play Store app, it might take a few minutes before you’re recognized as a tester.
If you encounter a bug or have a suggestion the best place to tell us about it is in the Google+ group.
Hoping to see you in the β-testers group,
