I recently had to start tracking my periods because of a cyst that burst! My roommate told me about this app and it records every part of your cycle: period, follicular, ovulation, and luteal. It tells you what kind of "witch" you are. This means where your period falls based on moon phases. I'm a white witch. You can share your cycle with your partner and your friends. It also sends the most accurate notifications like "If you woke up with less than 5 pimples on your face, consider today a win." I woke up with 3 that morning.
