SpeedTrace: GPS Speedometer

SpeedTrace turns your iPhone into a beautiful, glanceable GPS speedometer and trip recorder. Driving, cycling, running or sailing — see your real speed in big, high-contrast digits, watch your route draw itself on the map, and keep a full history of everywhere you've been.

Free to download. No ads. No account. No tracking. Everything is a one-time purchase.

— NINE SPEEDOMETER FACES —

• Classic: the original arc gauge, free forever

• Minimal, Retro LCD, Analog, Neon, Vintage, Rally, Turbo and Digital Cluster

• Try any locked face for 30 seconds, out on the road, before you decide

— BIG, GLANCEABLE SPEED —

• Large, high-contrast readout you can read at a glance

• Switch units instantly: km/h, mph, knots or m/s

• Live altitude, compass heading, and session max & average speed

• Honest GPS status — we never fake a confident reading when the signal is weak

— HUD MODE —

• Mirrors your speed onto the windscreen after dark

• Green while you're clear, red the moment you're over the posted limit

• Landscape, full brightness, controls fade away

— LIVE ROUTE MAP —

• Watch your route draw itself on the map in real time

• Follow mode keeps you centred and oriented; pan freely anytime

— TRIP RECORDING & HISTORY —

• One tap to start; keeps going with the screen off

• Automatic recording (optional): switch it on and driving starts the trip, parking ends it

• Every trip saved with distance, duration, max/average speed and elevation

• Detail view with your full route plus speed and elevation charts

• Share any trip as a card with your route drawn on the map

• Export as GPX or CSV to analyse anywhere else

— SPEED LIMIT & ALERTS (optional) —

• Shows the posted limit for the road you're on, using OpenStreetMap data

• Coverage varies by country and road; where no limit is published, SpeedTrace says so instead of guessing

• Gentle voice and sound alerts when you go over

• Fully optional — leave it off and the app uses no network at all

— LIVE ACTIVITY, WIDGET & SYNC —

• Keep your live speed in the Dynamic Island and on the Lock Screen

• Home-screen widget for a quick glance

• iCloud sync keeps your trips on every device you own

— 0–100 ACCELERATION TIMING —

• Time a standing start: 0–100 km/h, 0–60 mph, whichever you use

• Runs are saved so you can compare them

— BUILT FOR EVERY JOURNEY —

• Day & night themes for comfortable driving in any light

• Six colour palettes for your dial

• Keep-screen-awake option so your speed never dims away

— WHAT'S FREE, WHAT'S PRO —

Free: the Classic dial, all four units, the live map, unlimited trip history, trip charts, GPX/CSV export, speed limit alerts, automatic trip recording, trip share cards, Live Activity, the widget and iCloud sync.

SpeedTrace Pro is a single one-time purchase that unlocks the eight other dials — plus every dial added in future, at no extra cost — along with HUD mode, 0–100 timing and the colour palettes. Individual dials can also be bought on their own.

— PRIVACY FIRST —

SpeedTrace has no servers and no accounts. Your trips, routes and speed history are stored only on your device and in your own iCloud. 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.

— QUESTIONS? WE ANSWER —

Something not working, or a feature you wish existed? Email support@mzjpg.com — a real person reads every message and replies, usually within a day. And if SpeedTrace has earned its place on your home screen, a rating or a few words of review means a lot to an independent developer.

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.
