Tap the side that won the point. It keeps love, 15, 30, 40, deuce and advantage, games and sets, plays the tiebreak at 6–all with the right serving order, and tells you when to change ends.
Scoring and serving rules are summarised from the documents above. Undo is unlimited, so a mis-tap is never a problem.
Points go love, 15, 30, 40, game. At 40–40 (deuce) a player must win two points in a row: the first gives advantage, the second the game. A set is the first to six games with a two-game lead; at six games all a tiebreak decides it.
First to seven points with a two-point lead. The player whose turn it is serves the first point; after that each player serves two points in a row, and players change ends every six points. The set is recorded as 7–6.
A tiebreak to ten points (win by two) played instead of a final set — common in doubles and league play. Tick the option and the score keeper plays it automatically when the sets are level.
After the first, third and every following odd game of each set, and at the end of a set if its total number of games is odd. In a tiebreak, every six points. The score keeper shows a change-ends notice at each of those moments.
At deuce a single deciding point wins the game, instead of playing advantage. In doubles the receiving side chooses who receives it.
