Chronocurl Pro vs RockBook

Chronocurl is a laser stopwatch system useful to calculate relevant information for curling players. The curling delivery is a complex process. In order to progress, it is very important to get accurate feedback in order to quantify the diverse parameter composing the delivery. Three main parameter define the trajectory of a curling stone: the direction, the rotation speed and the linear speed of the rock. Chronocurl quantifies the linear speed of the curling rock when it cuts the laser beam. Using the value of speed, the player can easily work on his consistency without having to refer visually to the distance travelled by the rock. The app lets you read speed data in numerous units such as km/h, mph, m/s. The app also allow conversion of speed data at the hog line into approximation of commonly used split times such as back-line to hog-line or T-line to hog line. Pro Version The Pro version of the app allows the combination of multiple Chronocurl within a single pratice. This way, Chronocurl will give you the speed of the rock but can also measure split times with great precision. The combination of multiple Chronocurl (up to 6 units on 2 sheets) multiplies the number of possibilities. The Pro version of the app also allows audio feedback. This way a player can receive his data without even looking at the screen.

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
