Comments on DaysyDay - Period Tracker for Android

★★★★★ bahbah salwa · May 30, 2023
Great to predict ovulation and when you're Fertile. Also, good if you are someone who only wants to chart their menstrual cycle and not only use the app for fertility or contraception purposes. Would definitely recommend
★★★★★ Jackie B · May 5, 2021
I've been using Days for about 4 years and couldn't recommend it more. Having a highly accurate and all-natural method of birth control is important to me. Customer service is very quick to respond and help me with any concerns as well. Thanks for everything!
★★★★★ Kelly A (KellzYea) · Apr 5, 2022
I love my daysy, but I really prefer the layout of the old app. I like the monthly view, fluctuating chart, and the last page that had average lows and highs. It was alot more user-friendly for me. I will keep using the original version for as long as I can. 5 stars for the daysy and customer care. 3 for the new app.
★☆☆☆☆ Lisa · Aug 15, 2021
This thermometer is useless without the app... App would not start!! I uninstalled and reinstalled, I restarted phone, nothing helps with starting the app. How is it that my $20 thermometer is more reliable them this $300 one?! Please fix your app.
★★☆☆☆ Morani landau · Dec 20, 2023
I gave notifications permission through the phone, but the app keeps saying I did not, so I can't set the synchronization hour or a reminder to check temperature. I wrote an email to your support team and the answer I got was instructions on how to take my temperature (I know how to do this since the age 6 years old). Why did you answer without reading my complaint?
★★☆☆☆ Claire R · May 25, 2024
I have had this app and the Days fertility monitor for years. It used to work well back when you could connect the monitor to your phone with a cable to sync it. Now it can only be done via Bluetooth, and it is incredibly different to use. Half the time it won't sync. I also hate that it insists that location is switched on my phone just to check in the app where in my cycle I am. Why is this information required???
