Is this fertility window accurate?

Question

Has anyone has succes by going off of this app

Answer

I did, the first time.
Gave birth prematurely to my son last Monday.
But yeah, first time I got pregnant (this time), I got pregnant having unprotected sex the day before Glow predicted my ovulation day to be. And they say having sex the day before ovulation and/or the day of is the prime time to get pregnant. We weren’t trying, I just happen to notice it was the day before my ovulation when I went to log the sex.
