Gin gets me through ,

Genuinely helped me get pregnant

I was pretty sceptical about the app; I didn’t really have much faith in it. However, I was surprised to learn how short a fertility window is and therefore became a bit more conscious of when I was more likely to conceive. Frankly, at 43, it seemed not just unlikely but almost impossible. I was hit and miss with using it but then glanced at it one month and realised it was close to the window... a few weeks later, I found out I was pregnant. After multiple miscarriages and an ectopic pregnancy to say I was nervous during my pregnancy was an understatement. 9 months later, our gorgeous son was delivered by planned caesarean. He is the joy in our lives and we cannot believe our luck. I shall forever be grateful to Glow and hope it helps other users as it’s helped us.

The community is disgusting

The app itself is easy to use and is almost accurate. Could do with a few bugs ironing out. It does the job and I was going to pay for a years premium until I started using the community feature. It’s what you expect from an online community. Repetitive but informative. The downside is (which is reflected in the stars awarded) the community rooms don’t seem to be monitored properly. Rules are disregarded in certain rooms specifically designed for the more difficult side of trying to conceive and some women are horrifically abusive. I’ve never encountered such vile comments on an online community and unfortunately Glow don’t appear to be proactive on the issue allowing the offenders to remain on the app and further their abuse on the population. The abuse ranging from name calling to wishing miscarriages on other women. I can’t seem to see any system in place to remove such users. With this in mind, I’ll be trying other apps with communities and seeing what they are like in comparison as I would like my money to go to a more safe and balanced community feature. To round up the review. Glow has a decent interface. It is almost accurate give or take a day or two. I advise using premom if you’re using OPKs and manually updating glow with the information. Steer clear of the community if you’re on a difficult journey as it will leave you downtrodden and shaken.

Highly recommend, periods & ovulation made easy to understand!

Absolutely love Glow! Five years and counting.
Everything about this app is so easy to understand & really helped me learn my cycle, even to the point where I fell pregnant within five months of actively trying (these features can be changed in the settings). I absolutely love the glow community, being able to speak with people from around the world that are having similar problems or share the same interests as you.
The only downside is I had huge problem linking to my Apple Watch 5, and when it finally did there were no quick adds like on ‘glow baby’.
I still have to log onto my phone to add anything, maybe that’s something to come in time.
