We have had this app for quite some time (several months). Unlike a lot of the reviews, we have not had huge issues with the location accuracy. It might be off a little bit, but no more than 1/2 a mile. We have the app on all of the phones in our family, which is 5 phones & overall are quite happy with it.
I also feel like a lot of the relationships in these reviews must already have issues because this app is in no way hurting our family or the relationship my husband & I have.
