Definitely worth the buy!
If you have even a passing interest in Tai Chi, this app will be an asset you won’t forget. You can watch the movements in slow motion with accompanying descriptive text. You can pause and rewind. It’s truly a spectacular tool for learning Tai Chi. This will give you plenty to work on. The music is superb as well. There are meditation instructions and VR that really take it up a notch. Great stuff.
