I loved the glow app! I love the way you can upload pics along the way and watch your belly grow! It was nice to have a place to ask questions and to talk to other moms that were pregnant at the same time with close due dates! Highly recommend! ❤️❤️

I've long given this app a 5 star because it's the best. I'm currently trying to log in to my account on a new device and I've been stuck at the SMS verification part, please what can I do, I keep requesting for a code and it never comes. (my phone lines are active) Kindly help in how I can go about this.

I've been using this app since March 2016, and it's been 100% accurate every month! Not only does it legitimately predict my periods, it was spot on with my fertile windows. I have 2 beautiful babies to show for it (one born in 2020, and I just delivered the other one in July!) My only critique is that I wish they had an option for tracking cycles without including fertility. I had my tubes removed after my last baby, so I don't need to worry about that anymore.

Love all the different types of logs that help make period and ovulation tracking more accurate. I also love all of the different support groups that give instant feedback. Edit: 11/2024 The app is still great but very annoying when trying to add data for the day you are bombarded with them pushing you to upgrade to the pay version to track more minut details.

Glow is a perfect place to be when trying to conceive. There are so many women there who have gotten pregnant, some have misscariaged, some are still trying and we get to learn a lot from everyone's experiences. My favourite is how easy it is finding cycle Buddies, sharing thoughts, going through same symptoms and same Cycle. The best part of it all is when Af shows up and we encourage each other not to give up but keep trying again and again till we see that BFP!!!🤰💝

I love the glow app.. My husband and I decided to try for a baby. I have had Glow for about 6 months and when we decided to try we got pregnant the first try. I'm 100% it because we knew when to try because of Glow!!! I'm so excited.
Your ultimate free tool for tracking your menstrual and ovulation cycles. Predict when you're fertile, track your symptoms, and conceive faster.
Use your phone’s camera to scan and download the Glow app.
Available on iOS and Android devices.
The Ovulation Tracker app combines multiple fertility awareness methods to help you pinpoint when you're ovulating. Our predictive algorithm uses your BBT readings, ovulation test results, and cycle length to narrow down your fertility window. Our app also uses your logged symptoms throughout your cycle (such as your cervical mucus, mood, and vaginal discharge) for more accurate tracking.
Yes, the Ovulation Tracker app is free to download and use. There's also an option to upgrade to Glow Premium. On the free version, as on most popular fertility tracking apps, you can access forecasts for your next period and fertile days, symptom logging (mood, cervical mucus, BBT, etc.), discussion forums, and educational articles on reproductive health. On Glow Premium, you can access more advanced charts to track your symptoms, BBT, and ovulation test results simultaneously.
Yes, the Ovulation Tracker app can help you get pregnant faster. On average, it helps women get pregnant in 3 cycles or less (based on a study of 35,920 Glow users in 2023). Use the app's predictions of your fertile window (your most fertile days) to time when to have sex for the best chance of conception.
While no app can 100% guarantee that you're ovulating, the Ovulation Tracker app is very accurate and the algorithm only gets better the more you log your basal body temperature (BBT), symptoms, and ovulation tests.
The Ovulation Tracker app is not a reliable standalone method of contraception. While the app's predictions are very accurate, they're not a 100% guarantee and also do not protect you against sexually transmitted infections (STIs).
Glow cannot guarantee success for every cycle, but the Ovulation Tracker app’s cycle tracking is robust, and the forecast will get more accurate the more data you enter. The more consistently you log your symptoms and body changes throughout your cycles, the more the algorithm can adjust for period irregularity. Talk to your doctor for more help with getting pregnant with irregular periods.
Yes, you can switch over to the pregnancy-tracking mode in the Ovulation Tracker app once you get pregnant. You can also download Glow’s Nurture Pregnancy app to track your pregnancy week by week, understand your body's changes, and see estimations of your baby's growth (with helpful size comparisons).
The Ovulation Tracker app stores your data in encrypted databases hosted on Amazon Web Services (AWS) using a secure storage engine called InnoDB, as well as TLS encryption (the industry standard) to prevent anyone from viewing or stealing your data. The Ovulation Tracker app also features an offline mode that lets you log your data locally on your phone and deletes your info from Glow’s servers.
However, if you enable this mode, you won’t be able to restore this data or access any reminders, daily health assessments and advice, or community features.
Yes, you can invite your partner via email to track your cycle with you. Your partner will have their own daily log, but there will be one period calendar shared between you. If you're in a female-female relationship and you both have calendars, the Ovulation Tracker app will show the calendar for the one who sends the invitation.
For women, the Ovulation Tracker app will hide info about your weight, cervical mucus, pregnancy tests, and spotting. For men, data about your weight, masturbation, and erection will be hidden.
Yes, you can record the results of any test strip you use in the Ovulation Tracker app. However, you will need to manually input the results, as our AI-powered scanner only interprets the results from our FDA-approved Glow Ovulation Test Strips.
