GSpot

GSpot lets you capture a high-quality car acceleration video in about a minute using just an iPhone, then transforms it into a pro drag-race style clip. It records metrics like 0-60 mph, quarter-mile times, braking, and 60-120 mph, while analyzing g-forces and speed data to deliver a polished, gaming-like video.

No OBDII adapter is needed—simply mount your iPhone in the car and drive. For more precise speed data, it supports VBox Sport and XGPS160, with plans to add other 10 Hz GPS devices. Get ready to compare performance across cars like RS7, M5, C63, Ferrari, Lamborghini, McLaren, Porsche, Bugatti, Koenigsegg, and more, and see how your power stacks up.
