Topcho is a web application that computes scores for users' attributes. Currently included attributes are Agility, Strength, Speed, Endurance and Intelligence. Results are directly comparable between all users: If user A has a score of 10, he/she is two times better than user B with a score of 5.
In order to get scores, users need to register through the Open Gym. Open Gym is a public storage of various exercises submitted by users. Mapped to each attribute, those exercises serve as the basis for computing scores.
