I love this app. It keep track of my periods & give me an average after a few month. There are some glitches like it automatically pops in the graphing chart. the upgrade version give more options on moods, graphing, sending the info to my e-mail, plus some more feature. I am still trying to find the website to also track online. Also I love that it keeps a record of my weight. Too bad it dose not keep track of my body temperature. I think it is worth upgrading.
