GPS Speedometer for iPhone & Android

PACE turns your phone into a precise GPS speedometer that reads your true speed from satellites — not your car's sometimes-optimistic dash. It's free, works offline, and supports both km/h and mph.

A real speedometer, not a gimmick

Most phone speedometers jitter because raw GPS speed bounces around. PACE applies a 4-reading weighted smoother with spike rejection, so the needle moves the way a real analog gauge does — steady, readable, and trustworthy at a glance.

  • Smoothed color needle that shifts hue as you speed up
  • Top-speed marker that records your peak for the session
  • Switch between km/h and mph in one tap

Custom speed alerts

Set your own threshold and PACE warns you the moment you cross it. Handy for staying under a limit, keeping a steady cruise, or just knowing when you've gone faster than you meant to.

  • Set any speed threshold you like
  • Optional audio community speed-camera warnings
  • Works in the background while you drive

Why GPS beats the dashboard

Car speedometers are legally allowed to read high and never low, so your dash often shows a few percent more than reality. GPS measures distance over time from satellites, giving you a calibration-free second opinion that's genuinely accurate on the open road.

  • No calibration needed
  • Independent of tire wear or wheel size
  • Accurate the moment you have a satellite fix

More than a number

Unlike a single-purpose speedometer, PACE quietly records the drive behind the number. Every trip becomes a speed-colored route map you can replay, with per-trip and all-time stats — all free to use.

  • Speed-colored route maps with replay
  • Per-trip and all-time stats
  • Driving rating that scores how smoothly you drive
FAQ

Questions & answers

How accurate is a GPS speedometer?+
On the open road with a clear satellite fix, GPS speed is typically accurate to within about 1 km/h and is independent of tire wear or wheel size. It can briefly lag during very rapid acceleration or in tunnels where signal drops.
Does it work without internet?+
Yes. Speed comes from GPS satellites, not a data connection, so the speedometer works offline. You only need a connection for maps and social features.
Can I switch between km/h and mph?+
Yes, in one tap. PACE stores everything metric internally and converts at display time, so switching units never changes your saved data.
Is it free?+
The GPS speedometer, trip recording, and stats are free. An optional Pro plan (€3.99/mo or €29.99/yr) unlocks advanced analysis and extras.
