What is Reddit's opinion of Menstruation Calendar ♪ Selene?

From 3.5 billion Reddit comments

I use Selene! It's a pretty neat app with various features (cycle, reminders, ovulation, fertile days, weight, you can even put smileys to express how you feel on that day) but I only use it to keep track of the start date because I'm so busy I need a freaking app to remind me when the bs is starting again lol.

here you go

For those interested it's called Selene! Link!
