Great for board games. I downloaded a half dozen different apps looking for one like this. So glad I kept looking - this is exactly it!
We like to “count up” instead of set a timer and we add a rule to all our games where the player with the shortest time gets a bonus (10 points) and the longest time pays a penalty (-10). Use with any game, but some lend themselves more easily to timing (Carcassone, Ticket to Ride, Catan, etc...)
