Comments on DaysyDay - Period Tracker for Android

★★★★★ Meshi Regev · Jan 15, 2021

Missing the statistics page with the average temperatures, ovulation fluctuation etc. Which is too bad because it was very informative. The calendar view which only shows one week at a time isn't as comfortable, I prefer the monthly view. I like that there are more options for recording notes that include explanations and also that notifications were added. Overall the app isn't as easy on the eyes as the Bayview.

★★★★★ 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!

★☆☆☆☆ Danelle Wessels · Aug 8, 2021

The new app can't do the main thing it's supposed to do: sync with the thermometer.

★★☆☆☆ JJ Giraffe · Jan 23, 2021

I have used the Days thermometer and the old app for years. I'm going back to the old one, as it is hard to see the monthly view and statistics. I find this new app very hard to navigate.

★★☆☆☆ 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?

★☆☆☆☆ 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.
