Mel

Using this App made it easier for me to determine a more precise day for when my cycle may start. It’s great for managing your cycles especially If your doctor ask you that one question , “ when was the last day of your last menstrual cycle?” Now you can answer with confidence.

Ads ruined this app

This app was great until it was over run by ads. It’s basically non-functional now and inaccessible. There isn’t even an option to pay and remove the ads.
