The Deeply Safe app lets you hear your own heartbeat while you sit. Before Google lets a new app into the Play Store, a small group has to use it for two weeks. If you have an Android phone, you can be one of them, and you get the app before anyone else.
You need a chest strap, Polar H10 or similar. A strap reads every beat as it happens. Watches and the phone camera give an average, a few seconds late, too slow to listen to.
Joining takes two steps, and you need to do both. Google only counts you as a tester when you are in the group and have tapped Become a tester.
1. Join the tester group
This puts you on the list Google lets in. Sign in with the same Google account you use on your phone.
2. Then, become a tester
Joining the group alone isn't enough. Open this link on your phone, tap Become a tester, then install Deeply Safe from Google Play. If it says you don't have access, wait a few minutes after joining the group and try again.
3. Sit with it
Use the app over the next two weeks, and please stay in the beta until the app is public, since leaving resets Google's count. If something doesn't work or feels off, write me at hello@deeplysafe.com.
