Shell App

Do you ladies think it's legit? Idk why I'm so skeptical lol it always works for me, but it seems like I find the baby's heartbeat in the same spot everytime. It's always in the lower left area. I'm 12 weeks 2 days and according to the app it says it should be in the lower middle at the this stage
