Customer Reviews


if you’re someone looking for an app that’s simple and functional, i can’t think of a better one. it counts down the days, avoids being overly feminine, and doesn’t focus on fertility being the main point of tracking— which is good for those looking for something with gender-neutral colors/designs, and those who have no reason or desire to track their fertility.

HOWEVER, do note that you have to pay to enable reminders and unlock most of the themes— there are other apps on the store that have the things i mentioned without making you pay for it, but if reminders aren’t something you’re needing and you’re okay with the default theme(s?), there’s no reason why you can’t use this one.

anyway, i’m someone with regular menstrual problems, so this app actually doesn’t help me very much. i use another app instead as my primary tracker since it allows me to record more information, since my averages aren’t a reliable indicator of when my next period is coming. if you’re someone with regular menstrual cycles and want a fun app to track things, this one does the trick. but if you have extra things to track because if menstrual irregularities, there are better apps out there.

still, i can’t get myself to delete this app, and my one complaint is that it has no widget.

Just the app I was looking for!

Great app that replaces my not-so-discreet Google calendar events! I love that it can predict your cycle. Super useful.

So helpful

I love this app! It is so helpful to not have to try and remember anymore.
