Reliability of ovulation on Glow

DD

Hi everyone!! So currently TTC baby#2... first cycle. According to glow, I should be ovulating next week. Which is awesome! We successfully conceived our first child with glow in 2014... but a lot has changed since then.. Anywho- how accurate have you found this app to be? I bought ovulation kit too, just to be sure! I just want to see what everyone opinion is on this app vs others. I preferred this one because of my DS.
