Kaltrix turns your drive into an informed one. It fuses cross-brand radar-detector telemetry with a fast, navigation-grade live map — so the road ahead is never a surprise. Most driving apps show you where you are. Kaltrix shows you what's coming: a real-time, crowd-sourced awareness layer built from drivers around you, laid over turn-by-turn navigation that actually knows which way you're facing. WHAT YOU GET • Live awareness map — a clean, tactical dark map that surfaces corroborated road alerts ahead of you, color-coded by type and confidence. • Navigation-grade routing — turn-by-turn directions with lane guidance, speed-limit display, and smart departures that don't open your trip with a needless U-turn. • Connect your detector — pair a compatible radar detector over Bluetooth to fold its signals into your map, or run in crowd-only mode with no hardware at all. • CarPlay built in — a purpose-built CarPlay experience: glanceable maneuvers, your speed and the posted limit, and awareness cues, all sized to your car's screen. • Trip history & replay — every drive is saved; look back at your route, speed, and a shareable trip summary. • Crowd-powered, privacy-first — you contribute anonymized, coarsened signals and get everyone else's in return. Your precise location is never shared or logged. BUILT FOR AWARENESS, NOT DISTRACTION Kaltrix is a driving-awareness tool in the spirit of the road-alert apps you already know. Everything is designed to be understood in a glance and to keep your eyes on the road. PRIVACY Sharing is anonymized and location data is coarsened on our servers before anyone sees it. We never log your coordinates. Read our full policy at kaltrix.app/privacy. Drive aware. Drive Kaltrix.
