Great program that wont run

I got to use it a bit and it has been helpful, offering a lot of good techniques and easy ways to slowly but surely change perspectivea for the better. However, it freezes on me 95% of the time. Using it has become an exercise in working with frustration, which is good but not what I paid $60 for. This is the only app I have that has these issues. Im running an iphone 4s, which is older but if youre goin to sell it to run on the device then it should really run. Would love to change my review to a 5 star if I could actually use the program. But until then...
