D-bl0ck ,


It's pretty accurate with when I'll get my next cycle but now that iv updated it it won't open AT ALL! The adds that pop up almost INSTANTLY are annoying enough especially that 2 come back to back so a simple 3 second process takes longer(yea I'm impatient, as a single mother with 3 kids my seconds count) so it's all very frustrating.. I'd like to not have to find another app being that I have as much time as history marked with this one (I also have lupus and NEED to know my period history and to back track into my calendar and mark it off, well just isn't realistic with my hands full)


Thumbs Down

Went to log my BCP today and my data is not there. Tried doing a backup and some data (if it’s correct) but not all is there. All of a sudden my period is 102 days over due when I’ve been logging faithfully.

This app use to be spot on calculating when my period will begin, but over the last few months it has been off anywhere from one to three days. It would be nice if this app let you put your exact type of birth control in or at the least let you set it for a twenty one day cycle out of twenty eight because getting reminders on my off week is bothersome. Also, it would be wonderful if the app integrated with Apple Health and Google Fit.

Will not backup

I like having the ability to keep track of my cycles and activities but no matter which way I try, the Auto Backup nor the forced backup does not work. Extremely frustrating and especially because after transferring to a newer iPhone, my account info will not load on my new phone. I have to start completely over and lose my 2+ years of history, while knowing that when I move to a newer phone in the future, I’ll have the same problem once again. Will probably find another app. 😡

It should be easy to transfer your data using "Backup via MyDays Backup". In your old phone use "Upload" then in your new phone use the same settings and "Restore". If you need more help just email us:
