Is there any app that’s for kids/teens Ive been looking but they all track ovulation and fertile days and I mean I know she can skip those settings but I was seeing if there’s anything simple so she can learn when she might start even get reminder that it’s coming maybe and just her cycle length and flows and stuff basic stuff
