How accurate is glow?

How accurate have you been on the glow calendar vs confirmation on actual ovulation strips? We’ve been trying to conceive now for 7 months (one miscarriage) and I’ve been using the <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> as my reference for ovulation. Has anyone found the app accurate or not accurate? Would like to hear your experience
