βββββ So far, I have absolutely loved using Glo! The app is easy to navigate, beautifully designed, and offers a wide variety of classes and content for all experience levels. Whether I'm looking for movement, mindfulness, or simply a moment to reset, Glo has been a wonderful resource. The instructors are knowledgeable, encouraging, and make each session enjoyable. I'm excited to continue exploring everything the app has to offer and highly recommend it to anyone looking to support their wellie

Fantastic app to keep up with periods and fertile dates and actually helps with special one interaction

I feel like I should know which phase (luteal, follicular, menstrual, oulation)I am going to be on a particular day. And what kind of mood swings and symptoms I can expect. Like I might feel like eating something sweet. So if you could add phases and symptoms that would be cool.

Have been using the paid version of this app for many years now, and for the last couple of years it has become terrible. Now, if you are a paying user you can expect: 1) Not be able to have only the notification that your period is coming; 2) Not be able to disable the assistant - every time you want to log your period you need to click through this obnoxious and useless info dump; 3) Get the information about your sex life and pregnancy intentions leaked or sold by the company (please google it)

Overpriced. You have to commit to a 6-month sign up basically for $10 a month. Which I was unaware of. I paid the money to take the perimenopause quiz only. To cancel your subscription you have to pay $25. That's absurd.

Very bad app. Many good apps are available at free of cost. They deduct my hard money. It's useless app. Never use it. I will fire a case on them. Lier and very big cheater app. I don't need your password. A very big lier. Dear woman we are educated. We don't need this type of app. They are lier. They don't send any message one day before deduction of money. otherwise I will uninstall their app. They are money sucker. They suck your hard money. I used a lot of app smarter than this. Lier, lie
