Very very nifty

Have you ever wished you could track all of your monthly physical and mental health symptoms to know for sure, when they happened and why? This app allows you to track all of that and much more. After 3 months of tracking your monthly cycle symptoms you can easily compare and understand exactly what happens and exactly when. It’s really an amazing app and well made too. So much customization and personalization. Every woman needs this app!! I love when I’m at a docs appointment and they ask all those questions like “when was the last time you had sex?” Or “what day was the last day of your most recent period?”. It’s a total game changer. Also it’s helps to know exactly what to tell your doctor. When you can see your period is changing or acne is worse than it was however many months ago you’ve since tracked it, you’ll never have to wonder if it was “all in your head” or “maybe your not remembering it right”. This app with the subscription is worth it for any woman out there that wonders about their ever changing monthly symptoms.

Very good, but could be better

UPDATE: The community feature is nice but there are some very rude and nasty ladies on the forums. Post with caution.

I really do love Glow, but there are a few things I wish the app had. First of all, I wish that if you are using the app to conceive a baby that after your “ovulation date” it showed “days post ovulation” instead of “days until next period”. I don’t know why but seeing “days until next period” makes me sad and most women are symptom checking after ovulation and I feel like that information would be more helpful. If you aren’t trying to conceive then by all means leave it as is. Also, when putting in symptoms, cervix position, BBT, CM consistency, etc, I wish there were more every day insights into how that matches up to where you’re at in your cycle other than just comparing to other glow users. I never know if what I’m logging is normal for where I’m at in my cycle and I never seem to match with the other users which makes me concerned. I do feel like the newest update is very helpful though and have learned a lot from glow.

It was great...before the update

I had this app for over a year and it was great. It gave me some scientific research facts, easy to use, excellent at keep notes and easily tracked my period. Until recently, the new update made it harder to log and re-log, it’s also harder for me to edit my notes when I need to add something. The cycle analysis is always in the way and it’s only promoting glow premium; I don’t mind the advertisement until it gets in the way of everything I need to do on the app. The security lock on the app is very good and convenient. The stories that every other glow user makes it feel like social media and it makes me want to stay on the app explore and communicate with all the other women on the app which makes me feel very warm and fuzzy every time I see women supporting each other on the app. I’ll wait for the next update but if it’s really not giving me easy and quick access then sadly I have to find a more simple and easy to period app to use. Hopefully the glow staff and creator can do something about the new updates. Thank you very much for taking my opinion into account.
