About

I build TeCluster, an iPhone app that turns your phone into a Tesla instrument cluster: the car's own speed, power and battery over Bluetooth, with Apple Maps that follows the destination you set in the car. Tesla Model Y owner in Korea; small software company (CGFlow). Ask me anything about Tesla's Bluetooth/Fleet APIs, iOS, or launching a car app worldwide.

TeCluster for Tesla - Your iPhone as the Tesla instrument cluster

Tesla has no display behind the wheel. TeCluster turns an iPhone into one: the car's speed, power/regen, battery and range over Bluetooth, with Apple Maps beside it. Enter a destination on the Tesla's screen and the iPhone starts guiding by itself, then ends on arrival.
