This highly adaptable Jass scorekeeping app, available for Android smartphones and tablets, simplifies point tracking for various Jass game types, including Schieber, Coiffeur, Differenzler, and Molotov. Its versatile design caters to diverse playing styles and rulesets.

Key features include:

• Multiple Profiles: Create and save separate profiles for different game settings and players, allowing seamless transitions between various Jass sessions without data loss.
• Easy Sharing: Share your current game profile instantly with another device via Android Beam (NFC). This is especially useful for situations like low battery or complex setup adjustments.
• Schieber Panel: Offers individual point entry (1/20/50/100 for Weis, etc.), complete round entry with multipliers (1x-7x), opponent point input, rotatable input dialog (for single or dual scorers), undo functionality, customizable target points, adjustable score per round (e.g., 314 for double cards), and comprehensive statistics. A dedicated area allows for recording win/match tallies.
• Coiffeur Board: Choose from 16 predefined Jass types or create custom ones (without images). Supports 6-12 rounds and 2-3 teams. Manual multiplier adjustment is possible, and the app displays statistics on achievable points and identifies when a team becomes unbeatable.
• Differenzler Board: Accommodates 2-8 players. Point announcements are hidden until initial points are entered, with automatic calculation of the last player's points. Last round scores can be adjusted retroactively.
• Molotov Board: Supports 2-8 players with streamlined Weis entry (3 clicks), automatic outstanding point calculation during round entry, and editable point values. Points can be entered precisely or rounded.
• General Scoreboard: A flexible scoreboard for a wide range of Jass variations, supporting 2-8 players, customizable target points/round numbers, and adjustable points per round (with automatic outstanding point calculation).
