I have been on the pill for the last 2years with never having a period in that time, I couldn’t even remember when my last one was! This app is amazing I put in the date and time I stopped taking my pill for good and it calculated when my next period was going be. Me and my Fiancé wanted to start trying for a baby, so it told me when the high chances of me getting pregnant was! Well it turns out I only needed to use this app for a month because first time round we got pregnant!🤗 now 12 weeks gone into the pregnancy🤰🏼, all thanks to this app.. our baby is due on the 28th feb 2019👶🏻

I’ve used this app for a few years now. I use it to track when my acne is flaring up or what time of the month I tend to experience certain symptoms. It helps me keep track of my frequent headaches which is really useful when I need to go to my GP and report when they’re occurring. I use it for the pill reminder too.
There are no other apps that I’ve found that let you do so much for free. The only thing that I think could be added is an option for if you’re on the pill and skip a period, just so it doesn’t mess up your period calendar!

Review on the app quality

It is a really good app as it can track when I am next due on my period. Not only does it estimate but it is also accurate it usually gets it right on the day. It helps to know when I need to use a pad and it doesn’t charge for installation and is absolutely free. If you are looking for an app to relieve stress and countdown for you then this is one of the best.
