Ok, this app was incredible for the past 7 years for me. It literally contained every cycle I ever needed to know about, and little health notes I wrote in too. Now suddenly it's gone from my phone (I downloaded it when it was Lilly period tracker and I notice the name changed so maybe that's got something to do with it?) Anyway, I have tried multiple times to try to retrieve this account, with no luck. Everytime I do the reset password to the email I KNOW it was linked to, it never sends. Help.

This app does everything I need and is pretty accurate. It also allows you to backup your data within the app, which is what many others lacked. There's also a social part to the app, which I don't use. Very minor annoyance is the "girly" theme and icon. Great job overall! January 2021- I'm still using this app! No issues with data transferring between phones. Always accurate. Still want you to consider changing the theme though. 😄

I have been using this app for years! And recently they have added ads that I can't exit out of and the ads are really long. I just need to look at the calendar for a second to see when my last period was and I had to wait for the entire ad to play while the doctor was waiting. So annoying. Please fix it so the ad doesn't have to start as soon as open the calendar

Couldn't live without this app. I have been using this app since 2015. And have had many different phones and yet I can still view everything from January 2015 to now. All my notes and how I felt and symptoms I was experiencing. I absolutely love this app. And it is accurate too. I will never use anything else but this app. There is so much more than just tracking your period. Blogs, ovulation days, reminders to take your birth control. And so much more.

I have been using this app for over 7 years now and it's been amazing. It's so easy to use and navigate. It's very helpful. I track my period with so much ease but one thing i would like for a change is send notifications when the period and ovulation due time is near, and also the due date as a reminder, instead of having to check the app every time.

Simple and easy to use, much prefer this app compared to the leading ones. Straight to the point and you can easily navigate through the pages. 5* for me. The only thing I would add is if like me, you have a medical condition (PCOS) - you should be able to turn the 'auto cycle prediction' off as my cycle is never on time or a preticular flow. Sometimes Im "brown" for two weeks THEN bleeding for two weeks. Other then that, its great!
