Accurate, and very user friendly!

I love this app so much. I am only using it to track my cycles for now, but I will be getting married in 6 weeks and I will definitely keep using it for family planning purposes. Its accurate, detailed, and easy to use. Also...its pink! ;) I highly recommend this to anyone who wants a fertility tracker, for whatever their goal is.
