Analysez vos parties de Jass
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Keep score for Jass, Chibre or Schieber in a few taps, ask Siri for stats and the pot, find your games in Spotlight. Free, no ads, with Apple TV.
Jasstat Pro analyzes your Jass games — Chibre, Schieber or Mise — and turns your scoresheets into statistics.
KEEPING SCORE
Create a group, add your players, start a 2, 3 or 4-player game. Entering a turn takes just a few taps: the trump, one team's points — the other score is calculated automatically — and the announcements, as a simple value or in detail. Double Spades and Clubs are supported, Schieben included.
FOLLOWING THE GAME
The cumulative score, the difference and the goal stay on screen at all times. The chart shows turn-by-turn progression: points, announcements, and the gap between the two teams colored by who's leading. On the Lock Screen, a Live Activity keeps the scores in view for every player, on every device.
UNDERSTANDING YOUR GAMES
Every game gets a mastery rating from 0 to 100 per team: it measures how the game was played — result, pace, domination — not just the winner. Beyond that, statistics break down by group, team or player: win rate, streaks, records, favorite trumps, teammate compatibility matrix, group competitiveness.
FINDING A GAME
A dashboard summarizes your activity as soon as you open the app. Inside a group, search covers everything shown — teams, scores, announcements, dates, stakes — and the filter by number of players narrows the list. The summary recalculates live.
PLAYING TOGETHER
Share a group via iCloud, with edit or read-only rights. Every entry syncs within seconds to all participants — you can follow the same game from multiple devices.
ON THE BIG SCREEN
The Apple TV app mirrors a group's whole activity on your TV: games in progress, full history, statistics by group, team or player, a photo gallery and a chart — so the whole table can follow without leaning over an iPhone.
SIRI AND SHORTCUTS
Say “Replay the last game in Jasstat Pro” — with or without the group name: a new game starts with the same players and the same settings. Also ask for the statistics of a player, a team or a group and the state of the pot, over all time or over a period. Examples: “Stats for Marc in Jasstat Pro”, “Stats for the Friends group in Jasstat Pro”, “Pot balance in Jasstat Pro”, “Pot paid by Marc in Jasstat Pro”. The commands are also available in the Shortcuts app.
SPOTLIGHT SEARCH
On iOS 18 and later, your groups, players, teams and games can be found from the iPhone's search — name, score, date, statistics, pot. One tap opens the right game directly. The index stays on your device.
ALSO INCLUDED
• Photos attached to a game, a turn or a player
• Per-group pot, with contributions and withdrawals
• Full backup and restore, automatic monthly backup
• French, German, Italian and English
• Built-in user manual
Jasstat Pro is free and fully functional: no feature is locked, no ads, no data collection. In-app purchases are entirely optional and simply support ongoing development. Thank you!
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
This version adds Siri and Shortcuts commands to replay a game and to check statistics and the pot, and makes your groups, players, teams and games searchable from the iPhone's search.
• New: “Replay the last game” with Siri and the Shortcuts app. Say, for example, “Replay the last game in Jasstat Pro” — or add the group name: a new game starts with the same players, colors, targets and options as the previous one, and its first turn opens right away.
• New: statistics for a player, a team or a group on request — wins, current streak, mastery score, best partner… — over all your games or over a period (this month, this year, the last 12 months…).
• New: the pot on request — balance of a group or of all groups, what a player has paid in, last withdrawal — with or without a period.
• New: your groups, players, teams, games and pot withdrawals now show up in Spotlight search (iOS 18 and later), with their statistics and pot. Tap a result to open it straight in the app. The index stays on your device.
• Fix: a game created or duplicated and abandoned before choosing the 1st player stayed invisible in the list while still showing a Live Activity. It now appears in the list and can be deleted (the 1st-player choice is asked again when you open it).
• Fix: near the end of a game, depending on the points entered for a team, the other team could end up with an incorrect score, and the wrong team could be shown as the winner. This calculation is now fixed; the app only asks for the other team's exact score when it's genuinely needed.
• Fix: the "Import an example" button on the starting screen (to create a first demo group) could silently do nothing. It now correctly imports the example group, with confirmation and progress shown.
• Improvement: a few display fixes on iPhone (navigation bar), and support for foldable iPhones (rotation allowed once unfolded, adapted layout on the game screen).
