SpeedTrace turns your iPhone into a gorgeous, glanceable GPS speedometer and trip recorder. Whether you're driving, cycling, running, sailing or flying, see your real speed in crisp, easy-to-read digits — then map every route and keep a full history of where you've been.
No account. No ads. No tracking. Your data stays on your device.

— PRIVACY FIRST —
SpeedTrace has no servers and no accounts. Your trips, routes and speed history are stored only on your device. We don't collect analytics, we don't track you, and we never sell your data. The optional Speed Limit feature is the only thing that touches the network — and only when you turn it on.
Download SpeedTrace and see your every move, beautifully.
Note: Continued use of GPS running in the background can dramatically decrease battery life. SpeedTrace only uses background location while you're actively recording a trip.
