Simulated trainings

To get you started fast, we created simulations that feel instantly familiar and are easy to pick up. Reaction simulations, burst simulations, kicking against time or reacting to different simulations with different kicks. We got it all and are constantly developing new ones for you to have for free.
After you are done with your session, you will get instant feedback of your training. Depending on the simulation, you will see hits, misses, velocity, reaction etc. from easy to understand figures. Share or play again to beat those stats. You'll get faster and stronger in no time.

Leaderboards & challenges

Do you feel like a friendly one on one? Challenge any other kicker from commnunity to a game of speed or reaction. See how you rank against the very best in our leaderboards. Time to see who's who once and for all.
The more you kick, the more our revolutionary algorithm learns from your trainings. We find your strengths and weaknesses and create a unique training feed for you to train smarter and develop faster.
