Where was this in my teens and 20s?!

I started using iPeriod based on a friends recommendation in 2011, and Ive never looked back. I have a very volatile and varied cycle, and thanks to this app I no longer have to rely on a calandar and counting to predict when my next period might come. I love the next 12 projected period feature and its so easy for me to see the patterns in my symptoms and average cycle lengths now; I use this app to plan vacations, to keep track of my fertility, and if needed I know that precise info is on hand for my doctor. I had one glitch with the app once, and when I wrote a problem report the iperiod team wrote me with a resolution within the hour. Amazing work, keep it up.
