Obsessed with this app!
Ive been using this app for probably 7 years now. Its absolutely perfect and I track so many things on it - my period, weight, workouts, sex, migraines, even my alcohol and cheat meals! The user interface is very simple and I like that from my calendar view I can see my mostly used entries (and I have the ability to choose what shows on my calendar). I literally use it daily and I highly recommend this app.
