Accuracy of ovulation using glow?

Nicole • Married to my love since November 2013. Baby due in April 2016. 👶🏼
Anyone who uses glow find that ovulation days correlate with predictions by glow? 
TTC for three months now, but not following ovulation that closely. Not pregnant yet, so will be trying to better track ovulation. Should we BD every day during fertile window?
Advice and input would be much appreciated. 😊😊😊
