Customer Reviews

Great to eh, pretty good.

I used to rely on this app so much more. As you have probably read, there are a lot of ads. I don't like them but I'm not upgrading it to pay money for something I can do on paper or in the calendar app anyway. This app has always been great at letting me know when I am ovulating and when I am close, due to start, and am late. Which is FANTASTIC. What I don't like is that for some reason it now tells me I'm late even after entering my latest period. I started, immediately entered the info, and then the next day it alerted me that I should expect my period the following day. Today is said I was 3 days late and I am already done with it. I don't need the false update. I just need one if I really am late. Otherwise it's fine. I'm not tracking much of the other info. I use it to keep track of my cycle and can talk to my doctor about anything if I need to by just adding the info to the app as I go. I would give it 5 stars if it didn't give false alerts.

Grest tracker, too many ads

I used to love this app. It was a great way to keep track of my period, along with any trends that tend to pop up monthly (since it has a feature that you can track the symptoms you may experience day by day). It also alerted me in advance as to when my period was due (which is great, since I cannot remember to keep up with counting days).

However, I'm seriously considering deleting the app and downloading a new one. There was an update and there have been nonstop ads since.

Open the app and pop up ad. Open up the calendar. Pop up ad. Open up the day of the week you'd like. Pop up ad. Accidentally open up the wrong day of the week so you go back to the calendar to open up the right one. Ad.

I've never been bombarded with so many ads in such a short time frame. I only need to have this app open for maybe two minutes and in that time a minimum of three ads are shoved down my throat. Equally annoying is that I might be in the middle of doing something on screen when the ad pops up. I go to click on something in the app just as an ad for some Candy Crush knockoff appears so I end up touching that instead, which opens it up on the App Store.

It's just too much for an app I open one week in a month for a couple minutes at a time. You'd think for me to use it so rarely it wouldn't matter but it really is that annoying. I'll probably end up deleting it.

Ridiculous ads, expense

The app changed from little ads on the bottom of the screen, to ads that makes you wait five seconds before allowing you access the app, or an ad that requires clicking on it and doesn't go away, so you have to close the app and restart it so you can hopefully get the five-second ad that will Eventually let you get into the app. It's so annoying that I want to export my data so I can get rid of this stupid app, but it won't let me export my data without paying a fee, the amount of which it doesn't disclose! I'm not going to buy data I entered myself, especially when I won't find out how much I paid for it until after the fact! Now I'll have to go through and write down two years of periods myself with pencil and paper to keep my data. I feel like my data has been taken ransom and they won't even tell me what the ransom is until I give them a blank check. What a huge waste of time, I wish I had never used this app and stuck with an old fashioned calendar.
