I expect it to be two parts - the part on the smartphone, and the part that plugs into the OBD port. Please advise when you install it. A pure app would not cost $200 - it has to be both the hardware and software to actually function to disable the phones.
If I had a new driver in my family I'd definitely be buying a unit... the beauty of ONCI supporting me to start a family while also having the ability to protect us at the same time.
