Love love love this app. It is great for what it is. I've had it for so many years and it is reiable and doesn't input anything without my say so. Now on the flip side: I have used this app for years and age is a game changer. I am older and my period is not what I necessarily need to keep track of. I need something for menopause/ perimenopause. It would be great to cover the whole woman experience in one app. So Developers, let's interview some women about what they are looking for in an app.

Not docking a star for this theme update, but it looks and feels unnecessarily cluttered. If I could customize all that, it would've made a difference (I've no use for anything pregnancy related); I immediately went back to the old one that's clear and concise (removes access to *all* new features though). Well worth the $3 to remove ads! I've had this on every device for years, no backup issues, and it's on point even if my cycle veers off track the month before, which really impresses me!

I have had this app for years and have loved the simplicity of it. NEVER had to deal with ads or unnecessary things. The calendar was clean and simple to manage. Get on record what I need and get off. NOW ads are all over and I'd have to pay $3.00 to remove them. Do you know how absolutely DUMB that is!! I get the update to a point but the calendar is now foggy and no longer shows fertility days or expected period days which I absolutely loved. This update with ads was so unnecessary!!!

Hi, thanks for the feedback! Could you check if you turn on Ovulation/Fertile and Future Period(Settings - Show/Hide options)? If the issue remains, you can send screenshots via "Settings - Bug report & Feedback” to help us locate it. Besides, the commercials keep our team running, but we will try to optimize it to reduce the disruption. Thanks.
