A great app in the making. It's new and some features are unfinished or missing – some skills don't have videos, no recommended plans/schedules or even just recs on how to train to unlock next skill, finished sessions have a delay in history – but the foundation is great: beautiful skills tree, great content both videos and text with instructions and form tips, clean and intuitive UI. Can become the best calisthenics app on the market, keep working on it!
