The KRAFTMASCHINE is a device to analyse the finger and upper body strength. It allows to find personal weaknesses and can create a traing plan to work on them. It continuously monitors your progress and adjusts the plan to maximize efficiency. To keep track of your personal progress you can analyse your past results and can compete in high scores and collect achievements to rise in the ranks (e.g. between your friends, gym or worldwide). Its also possible to just train for yourself and not compare with others, choose what best suits you and motivates you.
Without the actual KRAFTMASCHINE hardware (https://kraftmaschine.org) its functionality is limited. You will not be able to do Trainings and Benchmarks that need the actual hardware, all other options are working.
