Read full description

I have played curling all my life at all levels. Going to the big Championships we always had rocktesters and coaches to help us analyzing and preparing for the conditions, but for club events you never really know what to expect. With Rock Book you will be able in advance to look at notes made by the club, the icemaker and other teams to help better get an idea on what conditions you will face. This tool will help you prepare accordingly. There is no worse feeling then having to figure out the ice and rocks for the first half of the game instead of jumping straight at it and play the way you want in full control with no surprises. Make your own notes to remember for next game or next time and share with your team and/or others. More exciting features will be added soon! Christoffer Svae, World Champion
