UPDATE: You now have to pay to do anything but log in the calendar. No point in logging if you can't access features. People complained, and now they're charging for all features. BYE GLOW!! I've had Glow for about 10 years. Used to be great, could track everything for free. But as the years have gone by, they've charged for more and more features. The pop-ups are totally out of hand. It's not as intuitive as before. Only good for tracking your period... For now. Other apps can do that as well.

UP:Lowering one star down again because it keeps sending my cycle is 90 days when I entered the dates recently. If you can find another app before entering too much data, do it! Do not use it! You will be bombarded by nonsense. I used this app for years, and always found it really helpful to track my period or symptoms. Now it's full of ads, premium this and that. The calendar is hidden and took me a while to get into it and update it. Sadly, I'll be looking for another app to replace this one.

I've been a long-time glow user. Having PCOS, it's important for my health to be able to keep tack of my period. I've used their pregnancy app as well, when I was expecting my first. Over time, it's been steadily declining or people like me who can't afford the premium option, or simply don't wish to pay to track their periods. It's now reached the point where it's confusing and free options don't even so much as tell you what day of your cycle you're on. I will be deleting it.
