GridNav vs Random Walk Compass

Paste a grid. See it on the map in seconds. GridNav puts MGRS, UTM, and lat-lon on screen the moment GPS locks, and works with zero signal. Built for soldiers learning land navigation, ROTC and OCS candidates, search-and-rescue volunteers, wildland fire crews, law enforcement tactical teams, and backcountry hunters who need a grid to land on a map without fighting their phone. WHY GRIDNAV • Read your position at a glance. Current location in MGRS, UTM, and lat-lon, in large high-contrast type. Pick which formats show and in what order. Switch precision from 4 to 10 digits. • Drop a pasted grid onto the map in one step. Paste an MGRS string from radio chatter, a text, or a notebook. The pin lands, the bearing shows, the distance counts up from where you stand. • Navigate where there is no signal. Download regions ahead of time, choose your detail level, and move with full offline maps. OpenStreetMap and USGS topo built in. • Read the grid without squinting. Clean MGRS overlay with labels at every zoom level. Adjustable opacity so the map stays useful underneath. • Save a spot with one tap. Drop a waypoint at your current position. Add a label, pick a color, tap to navigate back. • Keep your eyes adjusted. Red on black night mode for long movements after dark. • Use it with one hand under stress. Big tap targets, low cognitive load, fast even with gloves on. Battery polling tuned for hours in the field. HOW IT WORKS 1. Open GridNav. Your current grid is on screen the moment GPS locks. 2. Paste a grid into the input bar. The pin drops and the bearing shows. 3. Move toward it. Switch coordinate formats with one tap when you need to call it in. WHO IT IS FOR Soldiers and cadets running land navigation courses. ROTC and OCS candidates preparing for nav tests. Search and rescue volunteers reporting grids back to coordinators. Wildland firefighters calling positions to dispatch. Hunters working public land where lat-lon and waypoints matter more than turn-by-turn. WHAT IT IS NOT Team chat, mesh networking, route collaboration, and tactical-platform creep stay out of the build. GridNav holds to one job: working a grid coordinate on a map, fast, with or without signal. PRICING Free to try. Drop up to three waypoints, read your live coordinates, paste grids, and inspect the map with no time limit. One-time purchase unlocks offline map downloads and unlimited waypoints. No subscription. Get GridNav. Then go.

Inside the Sun, newly created photons take an average of 100,000 years to reach its surface. They do not travel in a straight line — they ricochet endlessly through solar plasma, absorbed and re-emitted in unpredictable directions until they finally escape. This is called a random walk. A journey that would take two seconds in a straight line becomes a hundred-millennia pilgrimage. Random Walk Compass brings that principle to the street. Spin the needle to a random bearing, follow it until something stops you, then spin again. No destination. No algorithm optimizing your route. Just a direction and whatever you find there. Spin Tap anywhere to spin the compass to a new random direction. Auto-Play Set the compass to spin automatically on a timer — any interval from 1 to 60 seconds. Walk Mode The compass face aligns to true North using your device's heading sensor, so cardinal directions stay fixed as you move through the world. Steps Mode Each spin pairs a direction with a random step count drawn from a range you set — a complete instruction for every leg of your walk. Voice Mode Clap your hands or make a sound to trigger a spin. The microphone listens for sound above a threshold you control, keeping your hands free. GPS Recording Record your route in the background, even when your screen is locked. Your path appears live on the map. Export Save your walk as a GPX file, GeoJSON, CSV, a map image, or an animated MP4 video.
