different info from different apps?

Question

So, we are ttc for over 8 months. (Paying more attention, logging, testing etc. for the last 4 months) I have glow, Ovia and fertility friend apps. Ovia has fertile window way later and longer. FF is in the middle and glow has it 3-4 days sooner. I've logged the same info on all 3. Periods seem to be close to the same on all 3. Anyone have any ideas? I'm trying to figure what one to follow (although trying to have sex as much as possible on all "Green Day's".) Thanks ladies!

Answer

I used Ovia and glow  always like Ovia better. But they were both wrong with my fertile window. One month I decided to use opk digital and I got a positive several days BEFORE I was supposed to even start my fertile window according to both apps. But Glow was waaay more off. Needless to say I got pregnant that cycle and the month prior (I only TTC for 2 months) I totally wasted my fertile window. Highly recommend opk. I used the clearblue advanced.

Answer

Just go by the opks. 
Glow was only off by a day for me but they're all algorithms.

Answer

I have Glow and Ovia as well. I have found that Glow tends to be more accurate predicting my fertile window than Ovia when considering the results of ovulation tests. I wonder if part of my problem is that I started using Ovia first before my period was regulated after stopping bc. I just go by the OPK now.

Answer

I personally didn't have much luck with the apps predictions. I have Glow, FF, and Ovia. I got frustrated, and read the book Taking Charge of Your Fertility. I learned more about my body's cues to determine when I was ovulating, and had better luck that way. I also started doing BBT after reading the book. 
Wishing you the best of luck! xo
