TTC & tracking fertility on two apps

So we recently just started TTC. We're not crazy trying, just if it happens it happens, but I've recently started tracking my cycle using Glow and Ovia. I've been using glow to track for probably 6 mos and just started Ovia. Has anyone else done this? I wanted to see what the other app said and both my fertile windows are different on both apps and feel as if Ovia is more correct due to feeling ovulation pains. Anyone else have this happen to them? Not sure if I should keep using both if the other is more accurate.
