Disclaimer: Period Tracker period and fertility forecasts may not be accurate and should not be used to prevent unwanted pregnancy. To forecast ovulation Period Tracker calculates 14 days before the projected start date of one's next period. Forecast accuracy depends on a number of factors including how regular one's cycle length is, when one actually ovulates during the cycle, and how many periods have been logged in the app. Anxiety, stress, diet, nutrition, exercise, environment, medications, age and other factors can also affect one's cycle from month to month.

I've been using this app since I started my period (at 11) and I think it works really well. As much as I wish there was no premium, they need to make money somehow, and luckily it's not unusable either. There's no ads and you can make a password so no one can open your app. With the widget, if someone is on your phone, they can't tell it's a period tracker unless they have the same app. But I really like this all because of one, security, and two it's accurate.

My period is also a bit irregular and I got sick of doing calculations every month. This app is pretty accurate and can keep track of your symptoms. Love it! edit: I won't be using the app any more. like others I switched devices and even though I attempted to get the backup working many times it just failed. so now I've been waiting for my period like a Neanderthal, no idea when it arrives or how many days since my last period.

I was able to restore all my data through 5 different phones over the years, but now it is glitching and every time I try to log in to backup or restore data I get an error message saying "Login error problem communicating with server. Please try again". I tried everything to get it to work but it isn't letting me back into my account anymore. If this doesn't get fixed, I sadly would have to download a new app to start over, and I wouldn't recommend this app to anyone anymore.
