Simply great

I have been using this app for my climbing training (almost 6 months now) and it has become one of my favorite tools. It helps me plan both endurance sessions and max strength work. The customization is excellent and makes it easy to adjust the plan to my goals. Simply great = 10 out of 10 would recommend
