Quick answer

Create custom dictionaries and retain words with puzzles.

F-Droid repository metadata

Keep track of your growing vocabulary through custom dictionaries. Every word is defined by you! Each definition can be adapted over time as your understanding improves. Features:
  • Specify part of speech, definitions, examples, and pronunciation for every word.
  • Paste excerpts into the reader to see existing definitions and easily add new words.
  • Practice with puzzles that test your knowledge, spelling, and ability to recall words.
  • Specify your confidence level to affect how often a word appears in practice games.
  • View language stats and share with friends.

What’s new

- Reduced install size

How to install

  1. Download the APK from the button at the top of this page.
  2. Allow “Install unknown apps” for your browser or file manager only, not for every app.
  3. Open the downloaded file and confirm the installation.
  4. If installation fails with “App not installed,” remove an earlier build of the same app first. A signature conflict is the usual cause.

Data safety

  • Every file is checked against its published SHA-256 before it is listed.
  • Files are scanned for malware on every update.
  • The permissions each app requests are listed on its own page.
  • Read the full safety policy for how we test, flag, and delist files.
