Glow vs Ovulation Kit

So my husband and I are trying to conceive baby number 2. I have the glow app (obviously lol) and I take my bbt every morning, I started maca and we just had sex with preseed (I’m laying on the bed with my feet up as I type this :) anyway my question is my glow app says my fertile days start on Tuesday but I also use my clearblue advance ovulation kit every first pee of the morning and since after my last period it has come up low, today when I took it, it said I was at a high fertility? Like I said my husband and I just had sex and I waited till I got a high fertility result to use the preseed. And we will continue to use it on my high and peak days. Also my bbt has not increased today either. My understanding with that is it only increases after you’ve ovulated. My question is which one is more accurate? Glow? Or the clearblue advance ovulation kit?
