Guess the year, flip the card to reveal.
V1 in development. Android-only sideload. Not on the Play Store.
Paste a public Deezer playlist URL. The app generates a printable PDF of QR cards for that playlist. During play, the player whose turn it is scans a card with the device camera, the app plays a 30-second preview of the track without showing the title, artist, year, or cover art on any screen, and players guess the year. The physical card is then flipped to reveal the answer. Scoring stays at the table; the app participates only in the audio layer.
- On your Android device, open Settings → Apps → Special app access → Install unknown apps and enable installation for the browser or file manager you will use to download the APK.

Compatibility: Android 12+ (API level 31+).
Each release publishes a SHA-256 of the APK in the release notes on the Releases page. On your computer:
shasum -a 256 tocarta-vX.Y.Z.apkThe output must match the value in the release notes. If it does not, do not install the APK; download it again from the Releases page.

No account, no login, no telemetry. Your playlist URLs and decks live only on the device. Deezer and MusicBrainz are contacted directly from the app for track and year resolution; no third party sees that traffic.
Decks are stored in local app storage. Uninstalling the app deletes them. Export the PDF if you want to keep a deck across reinstalls.
