SmartRace is a software for Mac, tablets and smartphones and is used for timing Carrera Digital tracks in 1:32 and 1:24 scale and via the Analogue mode also for analogue tracks (e.g. Carrera Evolution, Carrera Exclusiv, Carrera Go!!!, Ninco, Scalextric or others). SmartRace either connects to the Carrera AppConnect adapter via Bluetooth or takes the measurement in analogue mode via the camera of a smartphone connected via SmartRace Connect
