Great replacement to my previous app

Was using Pink Pad that closed for good. I was looking for a menstrual app that worked in the landscape view. This was one of the only ones I could find with that feature. Awesome app! Not only do I have landscape view but it separates into a split screen and I can see my cycles at a glance and the intervals. Being completely irregular makes that feature invaluable! The one thing I don't like is not being able to view my entire Notes without clicking into the day as if I am going to modify the Note. Otherwise it’s perfect for my needs.
Update:clicked into the app right after writing this review and figured out how to read my notes w/o clicking into them. Love this app more than my old one now.

Mostly accurate for me

I have been using this app since 2012 consistently, which, if you think about it, 6 years is a fairly long time for a phone app, for me at least, and it has been nearly spot on (heh) since the beginning. Probably why I keep using it! Occasionally I'm a bit earlier/later than the app says, but only by a day or three at the most, which is probably pretty normal. I love the reminder for breast checks, and the fact that I can customize my reminder message it is on its way. “ALL HANDS ON DECK!” 😬 This app has never crashed on me. I use the free version and the ads aren’t all up in my face, which I genuinely appreciate. I will continue using this app for as long as possible!

Best Pink pad replacement

I used to use pink pad but after 2 pregnancies which meant I was several years period free so didn’t need an app. When I was in need again I was in need of an app that would let me enter my own data instead of auto filling in when it assumed I was on my period. Love that this app lets me customize my data log to my needs. It has just enough options in the free version to satisfy my needs. Love that you can add personal notes on individual days too. So far I love it especially after trying many other apps and being highly disappointed.
