Gps Speed Tachometer

GPS Speed Tachometer is your precise GPS speedometer and trip tracker: see live speed, average & top speed, distance and duration — plus a route overlay on the map. Keep a ride log and export clean PDFs.

Key features
• Live speedometer via GPS (km/h, mph, or knots).
• Stats: average speed, top speed, distance & duration.
• Map & route: view the recorded path on the map.
• Ride log: list of trips with details; open or delete entries.
• PDF export: create a shareable PDF with map and key metrics.
• GNSS info: satellites in view/used, C/N0 signal, azimuth/elevation, PDOP/HDOP/VDOP.
• Simple controls: one-tap start/stop

How it works
The app uses your device’s GPS to measure movement. Live speed comes from position changes over time. Average speed is computed as total distance ÷ total time, and top speed is the highest reading of the session.

Logs & Export
• Every trip is saved to the logbook for later review.
• PDF export creates a neat document with map, distance, duration, average and top speed (a full-screen ad may be shown before export).

Privacy & Consent
• No account required.
• Location data is used locally for display and logging only.
• Ads via Google AdMob keep the app free. On first launch we ask for consent (UMP); you can revisit privacy options anytime in Settings.

Permissions
• Location (GPS): to compute speed, distance and show your position on the map.
• Notifications (Android 13+): ensures ongoing tracking runs reliably in the background (foreground service).
• Internet: for map tiles and ads.

Notes
• GPS accuracy varies with environment (tunnels, urban canyons, weather).
• Do not interact with the app while driving — safety first.
• Not intended for official measurements or calibration.

Enjoy measuring, tracking and exporting your rides!
