Basically Useless – Clue Period Tracker & Calendar Review

I’m deleting this app because it is almost never correct. In two years of using Clue, it still hasn’t figured out my cycle is 21–not 28–days. They also removed their “fertility window” tracker because it was so inaccurate, so that tells you pretty much everything you need to know.
