after using flow for years I wanted to see if there was an app where I can track my period without paying. this is worth it because you just pay a small one of fee to have ad free experience and I save 30 quid a year which is what I was paying for flow. it does exactly what I want, just simply track my period, something I don't think paying for is worth it.

I have used this app for the last 5 years and it does the job. Simple tracking, easy to add notes or change ur period start date. The ads aren't overbearing easily can cancel them and do not last 30secs until you see the X. I love it. Will buy the ad free one as a thank you to the developers for making a practical period tracking app.

honestly love this app been using it for years now (5 or more) there is small banner ads on the bottom but you hardly notice them, occasionally there are full screen ads but always a clear 'X' in the top corner (unlike some apps with invisible 'X') just recently bought the 'ad free' which was a small fee of £3.19, bought it to support the work of the developers as this app is amazing. the predictions are usually on point even for someone like me who had very unpredictable periods for a long time
