Fertility Friend vs Glow accuracy

S
I am a bit confused as to which is more accurate. I take my temp 5:40 AM on the nose every morning everyday (weekends included). Glow isn't very clear if I O and I don't have a coverline and FF shows I am 3 dpo. Which chart do you think is more accurate and what day did I O?
