User Reviews

Very much appreciated UI over other apps I've tried. Quick response from developer regarding feature requests. Top notch!!

It's a great little app but unfortunately whilst I used it yesterday for a really big game, I realised that the period clock continues to run after an official review. The period clock in the WFTDA rules state that the period clock only restarts WHEN the jam starts, not when the teams are lining up, which during most official reviews, they're already on track. Please get it sorted!
