Awesome app

It really is a wonderful app. Very accurate with gorgeous and varied themes! Easy to use and edit info. My complaint is that there's too much of it. Lots of unnecessary bells and whistles. Been looking for something smaller and simpler, but so far I can't find one that looks as good and has such good reviews! Hoping the devs will consider making a smaller, more basic version! Just want a calendar with the marks on the days a year back and a year out. That's it. No graphs or symptoms or forums or multiple ways to see the same info. I don't mind the option to mark the days I have sex because I do see the value in that. The only things I would add is an optional reminder when my period is late (maybe 5 days) so I can remember to input my info or take a test! Also I noticed a lot of other apps will send my husband a reminder. That's pure genius. So maybe there's a better app out there for me, but this one is terrific and I highly recommend it if you want lots of info and options. I have been using it for a year and loved it!

I can't believe I paid for this

This app routinely erases data I've entered. I'm on day 5 of my period--I open the app and it says my period is expected today. It has two consecutive recent days both marked as "day 1" of my cycle, with another couple of days I'd marked as period days totally empty. I go in to manually fix everything--not the first time--and it repeatedly changes the data when I switch between days. You're supposed to be able to extend your period day by day. Probably about 70% of the time, it doesn't give me that option, only the option to mark the day as the first of a new period. To fix that, I have to go back and delete every flow day, then try to redo it--but like today, that often results in more random data erasure by the app.

That this app calculates "average cycle length" but doesn't give you the option to exclude particular cycles you know are wonky (just ALL cycles over or under a certain length), and sends panicky push notifications about your "late" period after exactly ONE cycle's worth of data, are both pretty major flaws, but kind of irrelevant since the app can't even be counted on not to erase the data you enter in the first place.

simple, easy-to-use but great features

I used the free version of this for over 3 years before upgrading to the paid version. I like it a lot--it is relatively simple, which some might see as a drawback but which I like. I don't need something fancy with lots of bells & this is perfect for me. In the past I have primarily used the app to track periods & related symptoms and make notes about timing of certain things ("love connections", as the app calls them, amuses me still). It's helpful to pull out my phone at the doctor's office and have a quick way to check my personal data. And now that my husband and I hope to conceive, I'm using the features related to fertility/ovulation as well. I like that they are customizable but again, without too many bells & whistles. All in all, a nice little app. Does just what I need it to and would expect for such a modest fee. (And the free version had most of the same desirable features--it's nice, too.)
