Twintig: Sjoelen Scorer

Sjoelen tonight? One phone goes round, everyone sees the standings, and nobody has to do the maths.

Twintig keeps score at sjoelen, Dutch shuffleboard. One phone goes round the group, and that is all you need.

THE SCREEN IS THE BOARD The four gates sit in their real order 2-3-4-1, exactly as they are on the board. Four taps and a game is in.

THE COUNTING HAPPENS BY ITSELF Bonus of 20 for every complete set included. You see at a glance who is ahead.

MISTAKES ARE FINE Fix a slip from game 2 while you are in game 4, and land back where you were.

WHAT PAPER CANNOT SHOW At the end you see how the evening went: averages, best game, and which gate everyone's stones went through. The scorecard can be shared as an image.

FOR EVERYONE AT THE TABLE Turn up your iPhone's text size and the app grows with it. On a smaller or older phone the input screen takes a shape with large plus and minus buttons. Works with VoiceOver and with Reduce Motion.

NO FUSS No account, no ads, no internet needed. The app collects no data — not a little, but none.
