Takes too long and then varies up and down by significant amounts. Useless in remote areas.
Accurate for a cell phone since I imagine it's based on GPS. Ad's are extremely irritating!
It doesn't seem accurate. Standing at the ocean in Maine, it read -50.
Is not accurate, no way to calibrate
Other than the ads it works fine. NO free RIDE
It gives me more info than what I hoped for. I'm fascinated by it
