Speed GPS – speedometer

This app turns your phone into a navigation instrument. Ground speed, position, altitude and the satellites overhead, measured live and shown the moment you open it. It all works offline, with no account.

WHAT YOU SEE

• Your live GPS speed, in km/h or mph, on a speedometer dial you read at a glance
• Your coordinates in decimal degrees and in degrees, minutes and seconds
• Your altitude, derived from the satellites: a GPS altimeter that needs no network
• Signal accuracy in meters, colored by quality
• Atmospheric pressure, if your device has a barometer

THE SKY ABOVE YOU

A sky view places every satellite where it actually is: elevation, azimuth, signal strength. Every constellation has its own colour: GPS, GLONASS, Galileo, BeiDou, QZSS, NavIC and SBAS. Tap a satellite for its band, its distance, and how long its signal takes to reach you.

A 3D GLOBE

The Earth in three dimensions, lit according to the real time of day, with your satellites in orbit around it. Fully embedded: no connection required.

RECORD YOUR TRIPS

Distance, duration, average and top speed, elevation profile and cumulative climb. Drop waypoints to mark a spot along the way. Recording continues when the screen goes dark. Three curves read during and after the trip — altitude, speed and pressure — with a two-finger pinch to zoom into the detail and a drag to move along the track. Export to GPX and open it in any hiking or mapping app; every trip stays in "My trips", with a summary to share as an image or a ZIP archive (map, charts, GPX).

THE NETWORKS AROUND YOU

A built-in Wi-Fi analyzer and Bluetooth scanner. Every network in range with its band — 2.4, 5 or 6 GHz — its strength in dBm and its security protocol: WPA3, WPA2, WEP or open. And every Bluetooth device found, with its name and signal strength. Enough to compare coverage, place an access point, or track down a device you mislaid.

MONITOR YOUR DEVICE

Battery, health, temperature, processor, memory and storage. Live power draw in milliamps, with the runtime left. And a sleep delay you set yourself — 15, 30 or 60 minutes of inactivity, or never.

BUILT TO WORK WITHOUT A NETWORK

GPS listens to satellites; it does not need the internet. Position, speed, altitude, sky view, globe and trip recording all work fully offline — in the mountains, on a plane, or anywhere coverage runs out.

WHAT THIS APP DOES NOT DO

No advertising. No account needed. No analytics. Your positions and trips stay on your phone and are sent to no server.

Free and ad-free. An optional donation is possible; it unlocks nothing — no feature, no badge, no theme.

Available in 28 languages.

This app provides GPS data as-is and does not replace a certified navigation instrument.

After your second trip, Speed GPS may offer to let you rate it on Google Play, without leaving the app. Rarely, and never during a recording.
