Ovia app??

Has anyone else tried this new app ovia? I just started using it afew weeks ago. And it's been right own time with my ouvaltion. I started testing this week. And it's been right now. Glow has always been off. I enter all info in everyday confusing. Anyone else having this problem with glow? Ovia said my ovulation week started Monday till tomm.. today I got high fertility smile..

Glow said I wouldn't start till Friday. And last month it was off of my ouvaltion date by 2 weeks. When I tested.
