Not as familiar with Apple (IOS) solutions. Most of the OBD dongles on the market work with Android or Windows thru bluetooth. Apple does not permit bluetooth connection in this way. Scantool does sell a wifi dongle. The reviews are low. It appears the wifi times out after 1/2hr?
I have a Scantool MX bluetooth connected to Android phone. My Dodge diesel RPM gauge is always off. I connect to a spare Android phone for live feed RPM while towing. I can go many hours with zero problems. The same Scantool MX connects to many vehicles. Information available depends on the vehicle. Every vehicle has different information available.
