Started great; total letdown

This app had so many features that I loved it at first. But it cant handle irregular cycles, and makes terrible predictions based on them. You also cant remove information if you accidentally enter it in. If you accidentally turn on a cycle start day, there is no way to turn it off without data disaster. It is lovely to look at, and it would have great features if it worked, but after trying for several months I am afraid it is a total letdown. I am still looking for a replacement.
