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.

Very slow app

Can you please fix the app so it’s not incredibly slow? Syncing takes too much time. It should be not more than couple of seconds instead it takes almost a minute. And it happens every time you open the app or you want to see old data. And then, all these popping calendars and log charts. It takes time to close them because guess what? It’s still syncing. Then I open a different app while this one is syncing hoping it will sync and I can look up what I needed but I go back and it’s syncing again.
If I didn’t input any data why is it syncing and taking my time?

I’ve been using this app for a few years already for period tracking. Recently I decided to try the premium but it charged me for the full year without giving me the trial period. Any app you try always gives trial before charging but it didn’t happen with Glow. Another thing the app is very slow. Whenever I open it starts syncing and takes some time so I just sit and stare at the screen. You can’t really do anything while it’s syncing because if you try to click somewhere else it freezes for a few seconds. I wish the app allowed me to customize what I see on my page besides my health data. I’m not that interested in community Some pages have too many unnecessary for me stuff that is distracting me. Overall, I liked this app before but now I don’t even more for being charged without getting trial.
