Life Saving

I have a very very unpredictable period and have had various problems with it showing up on time. I have had this app since my very first period and has helped me through every one since. I love that it changes its predictions based on my inputs and counts down to the predicted next flow. I have also had three different phones/iPods with this same account and I never lost any data (knocks on wood). Absolutely amazing.
