One purchase gives you JassMind’s features, without a subscription or additional in-app purchases. Card recognition, call comparisons, practice rounds, scorekeeping, quizzes and bundled Jass reference answers run locally on your device, even without an internet connection. No JassMind account required.

App updates, optional AI model downloads and voluntary reports need internet access.

JassMind helps you learn and accompanies your real Jass games: play full practice rounds, compare calls and keep score. Use German-Swiss or French-suited cards, in English, German, French or Italian.

Full rounds with your coach
Practise Schieber, Coiffeur, Differenzler, Sidi Barrani, Pandur, Guggitaler, Molotow or two-player Schieber against computers. Each deal uses the selected variant’s cards and rules. Tap the question mark for advice calculated from your hand and publicly played cards. Review your decisions afterwards. Practice covers one deal, not a complete match. Sidi Barrani and Pandur start at the final bid, without a full auction.

Scan and check your hand
Photograph nine cards, choose a saved photo or enter cards manually. The large shutter stays available with hand movement once the camera is ready. Automatic scan lighting assists capture and can be switched off. Review recognition and correct uncertain cards. Lighting, angles, blur and covered cards can affect the result.

Understand the call comparison
In Schieber, choose forehand or “Partner has pushed”. Analysis accounts for whether you may push and who opens. Compare the expected point lead over the opponents, including your multipliers and enabled bonuses. A separately labelled percentage shows card majority in simulated rounds: at least 79 of the 157 card points, excluding those additions. Opening advice follows your position. Save hand analyses locally.

Your digital scoreboard
Scan won cards to help count their points, then check the result. Record scores and rounds for Schieber, Coiffeur, Differenzler, Sidi Barrani, Pandur, Guggitaler, Molotow and two-player Schieber. Adjust available table rules, resume saved games, undo entries and view final results and local statistics. Eight-card Pandur hands are entered manually.

Quizzes and Jass knowledge
Practise with 300 prepared hands: 100 each for Schieber, Coiffeur and Differenzler. View explanations and local progress. Quiz answers are recalculated for your selected game rules. Look up bundled Jass rules in chat.

Optional AI on your device
On compatible devices, an optional downloaded AI model adds chat answers and Schieber explanations. It needs internet for the download and enough storage; afterwards inference runs on your device. The practice coach needs no AI model. Model downloads use Wi-Fi by default; using mobile data requires your confirmation. AI speed depends on the device. With AI off, chat shows the closest pre-written answer, which may fit the question less well.

Voluntary reports use the internet. The app contains no usage analytics or advertising trackers. Simulations and AI answers are learning aids; they can be incorrect and do not guarantee a win.
