Nolio's goal is to provide an interactive tool, in the form of a web application, to improve and simplify the relationship between coaches and their athletes. Nolio allows coaches and athletes to improve their collaboration (monitoring, feedback, communication and planning). The coach accesses the online platform and can then use it to follow the progress of the training of his athletes with the help of data collected during the training sessions. Athletes will be able to access their space, synchronize their connected sensors, observe the sessions planned by their trainer and enter the measured data and their sensations felt during the sessions performed.
