NavGlance - GPS speedometer & altimeter
GPS speedometer & altimeter
NavGlance is a GPS instrument for sailors, pilots, drivers and hikers. Speed, altitude, heading, position and G-force in large, high-contrast digits you read at a glance, in direct sunlight or in the dark.
No maps, no routing, no account, no tracking. Just the numbers, arranged the way you want them.

Your screen, your layout
Hold any readout to arrange your screen. Add readouts, make them big or small, drag them into order, and use the same readout twice in different units. Each layout remembers its own units, and landscape can have its own layout. Car, Boat, Hiking, Flight and Race are ready to use, and the welcome screen starts you on the one that fits.
A look for every journey
Choose your look; every theme works with every layout. Two are free: Dashboard, a modern instrument cluster with a speed arc that marks your warning zones like a redline, and Classic, the display you know.
NavGlance Themes is a one-time purchase that unlocks every premium theme – including future themes: neon grids, a Cold War missile silo, brass and oak, fjords and spruce forest. Themes are a bonus; everything the instrument does stays free.
Try any theme live, on your own running display, before you buy. Some backgrounds move with your speed: choose how fast in Background motion, from walking pace to an airliner, or turn it off.
Anchor guard
Set the anchor point where you lie and choose a caution radius and an alert radius. If the boat drifts outside, NavGlance alerts you with sound, vibration and a notification. Anchor guard keeps watching while the screen is locked or you use another app.
HUD mode
Place the phone on the dashboard and the mirrored display reflects right side up in the windshield. Auto brightness turns the screen up for a clear reflection.
Warnings
Set caution (yellow) and limit (red) thresholds for speed and G-force. The digits change color when you cross them.
Spoken speed
Let NavGlance announce your speed at the interval you choose, in the voice and language you pick. Handy when your eyes belong on the water or the road.
Apple Watch
Speed and altitude on your wrist, with the same tap to change unit.
