Great but not 100% Accurate

I have been using this app for years now. I keep track of my period because it’s so irregular. It’s great to record your period cycles and your moods and current symptoms but not to calculate when your ovulating and it’s not accurate in calculating your next period either. You can’t base yourself 100% on an app. There has been times it does predict my next periods and other times it’s way off, because not every woman is the same of course. Be really careful in not trusting when it predicts your days of ovulation, it tells you that it’s high risk in getting pregnant and to be careful if your going to have sex if your avoiding pregnancy. I have tested these predictions and it’s completely off. I have taken ovulation tests just to see if it’s accurate and it’s not. I have taken my ovulation tests and it says I’m ovulating on days the app it says that I’m not and it’s low risk to get pregnant and it says I’m ovulating when clearly the test I’m not. Definitely not 100% and you should never trust an app to to tell you what your body is doing or not. If avoiding pregnancy don’t use this app for that. Use other methods. It’s great for other things just not for other important stuff.

Only keeps the data you don’t want it to.

When I decided to move from Eve (for period tracking) to Glow (for TTC) I thought “yay! They’re by the same developer and they already have all the detailed tracking I’ve been putting in for over a year. This should be super accurate!”. Guess again. They don’t attach ANY of your period data or symptoms to your account, so you have to manually enter it. I’m even on their annual subscription to get access to better “predictions”. You know what would help predict stuff? All that data I spent over a year adding into the app you have under the SAME subscription umbrella that I paid for.
You know what DOES transfer form app to app and shows *in my public profile*? The comments I leave on their “articles”. Cool. Glad we got those priorities straight guys.
I even emailed support because I was certain it must be a glitch. This is the whole reason these apps exist. Why would they not attach my date to my profile? Or at least give me the option to transfer it from app to app within my phone? Nope. They know, they don’t care. They told me to add my last few cycles in manually to get started.
Don’t waste your money.
They also have a horrific track record for privacy and safety which I found out while googling to find a work-around. Go ahead. Google them and enjoy the horror of the fact that they let any person with your email address pair themselves to your account. Lovely. What a stalker’s paradise.

Got worse over the years

I’ve had this app for YEARRSS which is the only reason I keep it, it has years worth of my logs. However I used to love this app so much, but over time it’s gotten so annoying. They redesigned the app, that’s fine, but when they did they made it to where every darn time you open the app it gives you an ad for their own premium account stuff. Never got the premium and never needed it, simply tracking my cycles on here I got successfully pregnant twice, one of which was full term and now my son. I’ve also successfully avoided pregnancy by tracking. So the premium is unnecessary cause all the “info” it gives you there is stuff you could just find on google. Idk the amount of premium ads is annoying. And it’s a bit harder to navigate the app now than it was a few years ago. Idk I say you’d be better off getting a generic tracker app, just so long as you can track your cycles you’ll be alright, this app is just filled with a bunch of extra unnecessary stuff. The only part I really like anymore is the community forums and chats/posts/threads. But again that was only useful when I was pregnant, as it gave me other expecting moms or experienced moms to talk to about my worries and stuff - but again - you can find groups like that all over Facebook. So yeah I hope that helps.
