Your flashcards call you.

Your phone rings like any other call. You answer, and practise your vocabulary out loud — no app to open, nothing to type.

Use the email tied to your Play Store account — that's how Google adds you as a tester. Free to test. No card.

Testing is open in 14 countries.

The honest version.

The app is built — what's left is Google's queue. A solo developer can't publish publicly until twelve testers have stayed opted in for fourteen unbroken days, so joining the test is simply the earliest way to get it. Once that clears it opens to public testing, then general release. Here's the whole ask, before you hand over an email address.

  • 01
    Install from a Play opt-in link Emailed once you're added to the tester list. Normal Play install, normal updates.
  • 02
    Leave it installed for 14 days Answer a few practice calls whenever suits — five minutes each. Starter decks are included, so there's no setup homework.
  • 03
    Tell me what broke In-app feedback button, or just reply to the email. Optional, but it is the point.

The part that actually matters: uninstalling early resets Google's counter for everyone, not just you. If two weeks on your phone isn't something you want to commit to, it's genuinely more useful to skip this one.
