Spot on red day calendar

Blair project

Its always a spot on red day calendar... I am able to perfectly plan my beach vacation, schedule my marathon race and travels because of this app. I get to enjoy all of the above because I have already foreseen when i’ll be grumpy and moody. And we don’t want that whenever we are travelling or running a marathon. So thank you!

Best app for tracking your period!


Been using it for more than 5 years. Hasn't given me any problem. I like it too that it allows me to set reminders (w/c I can just tick off) to take my meds. I can set the dose & the time I should take it. It's not just a period app but an all-around health tracker tracker too. Love it!

Very reliable


I've been using this for almost 3 years now. The good thing about this is that, it also has pregnancy option. Great job!
