Which one is more accurate ? I’m confused 😭

I set both on my last period which is June 12 2018 & I know I’m positively pregnant but these apps are saying different weeks pregnant I am. Which is more accurate ? The <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> or the pregnancy+ app ? Help😵😭
