Great!
If I hadnt bought this app I probably would have never finished Insanity. Its awesome as you have your own portable workout. Only problems I notice is that whenever I accidentally type in the wrong weight/measurement I cant go back and change it. Also the audio can sometimes be slower than the video. Other than that I feel like its $8.99 well spent.
