Customer Reviews

Best Ever

This app is great for women of all ages! Whether you're trying to conceive, trying to avoid conception, or simply just tracking your period it is a great way to do so! The app is literally like my friend. It sends me reminders (can be turned off) to drink water throughout the day, when I am fertile, and when I am due for my period! It also gives you great tips depending on where you are in your cycle! Another great part of this app is the community. The app allows you to talk, share and learn about health concerns, contraceptives, literally anything feminine health related! 10/10 recommend it to all my friends!

Love , Love , Love! Must Have.

Glow is a must have app! It's amazing is you are trying to track your period but also if you are TTC!! 😊 At the beginning I wasn't too sure because it was kind of throwing my periods off as sooner , but I noticed the more you track the more the app is more accurate. It's like it has too get to know your body. I love it!

The Glow community is great. I have met some pretty amazing women on there. 😊 I highly recommend it. I also have recommended it too friends and family!
I love glow!

The only period and ovulation app you need!

I've only had this app for a little over a week, and it has been pretty accurate with my fertile days as I usually feel when I'm ovulating. It's also pretty fun to log my days in. I like all the tips and information Glow gives me daily, as my husband and I are trying to conceive baby#2. I like this app way better than my old tracker app. We'll be pregnant soon with the help and tracking of this app, I know it. Highly recommend.
