Test Ferrabelle before anyone else.

Ferrabelle for Android is almost ready for Google Play. Before Google lets a new app launch on Google Play, at least 12 people have to test it for 14 days in a row. I would love for you to be one of them.

What you need

  • An Android phone with Android 7 or newer. Health Connect features need Android 9 or newer.
  • The Google account signed in on your Android phone.
  • To be 18 or older.
  • A few taps a day for 14 days.

How it works

  1. Sign up below

    Use the Google account that is signed in on your Android phone. That is the account Google checks when you join the test.

  2. Watch for the invite

    When the test opens, you get one email with a Google Play link. Ferrabelle is free, and testers are set up as Google Play license testers, so unlocking Pro ($4.99 for everyone else) uses a test card and never charges you.

  3. Join and install

    Open the link on your Android phone, tap to join the test, then install Ferrabelle from Google Play like any other app.

  4. Use it for 14 days

    Google counts the days you stay in the test, so please stay in for at least 14 days in a row. Keep the app installed and open it now and then: log a period, a lift, a weight.

  5. Tell us what you think

    Send feedback from the Ferrabelle page on Google Play, or email ferrabelle@proton.me. Short and blunt is perfect.

What I can see

Nothing you log. Testers get the same app as everyone else, so your data stays on your phone. Google Play shows me crash and performance reports for the app, and those never include your health data.

Ferrabelle is a wellness app. It is not a medical device and not for contraception.

Sign up

No iPhone version yet. Pick "Just tell me when it is out" if you only want the launch email.

To test, use the Google account that is signed in on your Android phone. Google Play only lets that account install the test.

What would you like?

We use this only for the test and the launch email. It goes to my private Discord channel and to my own inbox, sent through Resend. See the privacy policy.
