The banner ads at the bottom are fine but having a full-screen ad every time I open the app is incredibly annoying :/ Always sucks seeing apps you've used for years just start adding progressively more and more ads over time. The app also seems to take much longer to load now than it used to (loading ads, probably), which is not ideal when you just want to quickly input some data and be done with it.

generally good, but having an issue where I used this app a while back, then went on the pill and had no cycle for like 3 years, then have come off it again and am using the app again. however it still has my old data, which means it does not include the 3 year break and is saying my average cycle is 138 days? can't seem to find a way to fix this. all else is good however

This app has been very helpful! It has many many many options, has no adds, and has plenty of privacy. It is free and is the best period calendar I have ever gotten. You can always delete data, which I find very helpful. It also helps tell you how you can get rid of cramp pain and helps you with mood swings, really any pain, emotions, support, ect. I deeply think that you should get this app, it is very helpful. And if you don't like something on it you can always change it or contact them.
