GPS Metrics
Live GPS, track, nmea & export
Free · Designed for iPad. Not verified for macOS.
Turn your iPhone into a precise GPS instrument: live speed, altitude, heading and position, a colour‑coded track, and NMEA output to any device on your network.
GPS Metrics is your compact and accurate companion on the move. See live speed, altitude, course and more, visualize your track on the map with color by speed, export GPX/KML, and send NMEA sentences over your local network to other devices or software.
Highlights:
• Live metrics: speed, (barometric) altitude, climb/descent rate, course, rate of turn, heading (true/magnetic), horizontal/vertical accuracy and timestamp.
• Map with speed trail: track segments are color‑coded by average speed.
• Export: save your trip as GPX or KML.
• NMEA output: send RMC, GGA, GSA, VTG and GLL via TCP server or UDP sender (local network).
• Coordinates: choose DD, DM, DMS, UTM or MGRS.
• Units: metric or imperial.
• Averaging window: smooth speed and climb/descent with a configurable time window.
• Battery friendly: enable “Battery Saving Mode” to use significant‑change updates.
• Keep screen awake during your trip.
• Theme: follow system or pick light/dark.
Privacy
• Your location stays on your device unless you explicitly export or enable NMEA output to a device you choose on your local network. No account, no tracking, no ads.
Requirements
• Location permission is required for metrics and track. Local Network permission is required for NMEA output.

What's New
- New maps: cleaner Streets, Outdoor and Satellite styles, with an always‑visible scale bar. Your last‑used map style is now remembered.
- Speed‑coloured track with a colour legend that scales to your top speed.
- Direction arrow on the map showing your GPS course; its length scales with speed and is adjustable.
- Improved follow mode: pan the map freely and it returns to following after a moment. "Fit" shows your whole track, then returns to the normal zoom.
- Barometric altitude as a separate reading, plus air pressure — with calibration to a known height.
- Climb rate now uses the barometer for faster, smoother readings.
- New metrics: Max speed, Compass accuracy and Pressure. Choose GPS or Barometer as your altitude source.
- Pause/Resume button that stops all sensors to save battery; your track is kept and continues when you resume.
- Reset button with an export reminder.
- CSV export added, alongside GPX and KML.
- NMEA output now supports UDP broadcast to every device on your network, with an in‑app setup guide.
- More accurate trip distance: standing still no longer adds distance from GPS drift; metric distance shows metres below 1 km and kilometres above.
- Settings reorganized, plus various power and stability improvements.
