PreRun.io

PreRun.io is GPS built specifically for off-road — pre-runners, rally teams, overlanders, UTV crews. Not a generic outdoor app with a "trail mode" tacked on. Built by people who actually drive in the dirt.

RALLY + RACING

- Pacenote Mode: 1-6 severity scale, tightens/opens turn classification, spoken pacenotes like a real navigator.

QUICK KEYS — THE FEATURE OTHERS DON'T HAVE

WHY THIS EXISTS

PreRun wasn't built by a mapping giant that added an "outdoor mode." It was built by people who actually go offroad and know what matters when you're bouncing through whoops at 80 mph. Interface works with gloves, in sunlight, at speed. Turn detection knows the difference between a note at a gate and a critical Y-junction. Every feature exists because someone needed it in the dirt.
