Very good app, easy to use and simple to have. I would like there to be a dark mode setting since my eyes are a bit sensitive, but I'm usually not on it long enough for the light mode to be a concern. Also, perhaps you can add more customization for the notifications, like a customizable birth control reminder.

This is amazing, I recently used this new app and all I can give is praise. Not only is it user friendly it has a lot of details. The only thing I wanna point out is the notifications, if there could be a bit more customisation on that part it would be great!
