UI is tricky. It won’t show you a full calendar month. That’s the part I dislike the most. I want to open the home page and not see just a week. Also that it doesn’t show a visual for ovulation. :( editing a period was kinda tricky, the “in - days” doesn’t make sense when my period is late, I put prediction setting for 2 month even 6 and it will still only show me 1 month ahead. I think the “periods” tab should be a small box in the corner you can open up. I’ll be finding another app. Cant track symptoms or take notes on free btw.
