Andamp is on Google Play. The beta gets each update before it goes live there, so you can try what’s new first.
To join, leave the email address of your Google account, the one you use in the Play Store on your phone. Testers are added by hand, so it can take a day or two. Once you’re in, switch to the beta on the opt-in page. Check back there now and then. From then on, beta updates arrive through the Play Store like any other update.

Your address is only used to add you to the beta, and it isn’t shared. It’s kept for as long as you’re in the beta: to leave, email [email protected] and it’s deleted. See the privacy policy.
