Every rink needs to get one of these now!!! Just had a game with 13 penalties and it was a breeze!
For the parent who is timid about volunteering for clock... this app is a no brainer. Very user friendly!
This app is amazing, every scoreboard/clock needs to be compatible with this app.
Game changer!!! Why did it take sooooo long!
Very intuitive to use.
