I love it!

I have been using the lite version for about a year. Then I thought I should try the full version and pay. BEST APP I HAVE EVER PURCHASED! I was able to back my information up by email and when I got a new phone all my data was still there. Also I think its pretty accurate on determining when you going to get your period give or take a few days but its worked for me. I highly recommend this app !!!
