    Tempdrop cuts through all the inaccuracies that can go along with basal body temperature tracking, and I love that it can be used by women who don’t have regular sleep schedules or have irregular periods.

    I want to be able to share Tempdrop with anyone who is willing to listen! I believe fertility awareness is highly under-utilized & I love how Tempdrop's team wants to increase education about FAM's.
