Phydeo offers 2 license options.
1- The free version.
This is an ad-supported version, which gives you access to absolutely all features. The downside with the free version is that you and the patient will see publicity when building or viewing exercises.
2- The Premium version.
This one is available at a cost of 9$ per month (6$ if a clinic purchases over 5 licenses). It is an ad-free version.
