No wifi.

Should say BT only

KevieM ,

Great cheap option

Out of all the OBD readers this is the easiest to use. It may not fully work if every vehicle but it’s great at pulling codes. Worth it!

HidesWireInWalls ,

Terrible UX

On iOS 16 gestures are not supported. So it’s quite difficult to switch apps. The UI in general is not intuitive and seems thrown together. There does not appear to be any EV support.
