Customer Reviews


The app is very disappointing especially given how pricey daysy is. When I sync my daysy app changes the days of my period after I have manually entered the days. Then it is not accurate in recording which days I forgot to take my temp. Also you cannot enter previous cycles so that the app can predict your next period you just have to start all over or use your previous app for cycle prediction until this one catches on. There is just a lot that needs work.


I think there was a software update and everything works fine now. I love daysy and the tracking app. I also use Kindara to track my periods as it is a little more accurate in its predictions. But I use daysy exclusively for Fam.

Three ⭐️ for the app, not the Daysy

The daysy is working wonderfully for me so far! I have been using it about 2 months and I will update my review after a few more months. But the app is not up to par with the daysy. Which is not the worst problem they could have! When I connect my daysy the app will alter the days I've enter, saying I didn't take my temp on days I know I did, or showing that tomorrow's data is available but today's temp wasn't taken (substituting today's temp for tomorrow and thereby "erasing" today's temp). It's a little glitchy and disappointing, sometimes makes me nervous that the daysy itself might not be working, but so far it's just the app giving me troubles.

Not user friendly at all! Needs work!

Can't put in your menstrual cycle for past dates, sometimes Daysy won't sync, it should be you can see the measurements on your phone right after so we can be 100% sure they logged correctly! I mean if we are giving up means of other birth control and we ARENT trying to get pregnant I need something I can trust. I can't trust it..the program itself is NOT easy to use.. while I love the idea of Daysy it needs some help in the application department, it's confusing and you should have the ability to enter more data, it's not what I expected. Sorry! Please work on the app this really could be amazing.
