Glow's inaccurate???

Question

According to Glow, I was suppose to start my period 5 days ago. I compared it with this other app I also use and that app say it should start today. So far they're both wrong.
They both have the same exact information.
What's up with that???
Anyone experience this "off period dates" with Glow or am I the only one??

Answer

Or you could just be late. You're asking technology to correctly predict what your body is going through. Two months ago I was 5 days late and this last month I was 2 or 3 days early. It's your body not the app.

Answer

I'm currently 16 weeks pregnant. On the day that I conceived, Glow told me that I had a 2.9% chance of conception. A few weeks later, when I found out that I was pregnant, I looked back, and it said 24%. I no longer trust this app. 😜 However, I am super excited to be having this baby, and my hubby and I are glad that we no longer have to figure out when we'll be ready to have another baby! 😉

Answer

My app says I was supposed to start 2 days ago, but i have a couple of days more before I'm supposed to.

Answer

Created by flawed humans.. It is an app for goodness sake

Answer

Glow was always spot on for me

Answer

Mine is only off by like a day or two

Answer

I just started using it as well. My period is off but you have to log everyday and it'll take a month or so for it to get on track.

Answer

How long have you been using glow? Do you always update your period start and end dates? I was using glow for a few months and tracking AF before I started to trust it. Now it's spot on. 
My ovulation is not so spot on. My ovulation test showed me ovulating on a day that I have only 11%, when I updated it it changed my cycle start date for the next month. AF is due one week from today... Hopefully she doesn't show up...
