Never lose signal on the road again.

Google Maps finds the fastest route. RouteSignal finds the fastest route that keeps you connected — scored for your carrier, mile by mile, before you ever leave the driveway.

See exactly where you'll lose data and voice, for how long, and which way to drive instead.

Pick a corridor and your mobile carrier to watch both real routes get re-scored — live highway geometries, detailed dead-zone milestones, and turn-by-turn pre-trip preparation.

Download before Fort Stockton. South of Fort Stockton both routes merge onto the same US-385 stretch into the park — roughly the last 110 miles are the shared dead-zone tail, the darkest driving on either route for every carrier. Grab offline maps, podcasts, and the campsite address while you still have bars.

How to read this demo: the routes, distances, and drive times are real (OpenStreetMap road geometry via OSRM, verified Oct 21, 2026). The coverage coloring and Signal Scores are modeled for this prototype from FCC reported-coverage patterns along this corridor — Verizon strongest in rural West Texas, AT&T in the middle, T-Mobile weakest — and are not live measurements or a guarantee of service. The production build scores routes from FCC National Broadband Map data corrected by driver reports.

How RouteSignal works

It's a trip checker, not another navigation app. RouteSignal plans the drive; the maps app already on your phone drives it.

STEP 1

Enter your drive

Start, finish, and your carrier. RouteSignal pulls the real route options and lays each carrier's reported coverage over every mile of them.

STEP 2

See the signal before you go

Every route gets a Signal Score from 0–100, the share of miles covered, its longest dead zone — in miles, minutes, and the exact spot it starts — and a timeline strip that shows the dark stretches at a glance.

STEP 3

Download the gaps, then drive

Export the winning route to Google or Apple Maps, get prompted to download offline maps before each dead zone, and know when you'll reconnect. Drove it and lost signal somewhere we said you wouldn't? One tap reports it — and corrects the map for every driver behind you.

Built for people who live on rural highways

Dead zones aren't an inconvenience when the road is your home or your office — they're a planning problem.

RV travelers

Pick tonight's route by bars, not just miles. Know before you commit to a 500-mile leg whether you'll be able to book the next campground, check the weather, or call for help when a tire lets go outside Marathon.

Van-lifers

The scenic route and the connected route are rarely the same road. RouteSignal shows you the coverage price of the pretty way — and which carrier's signal actually survives the desert you're about to cross.

Remote workers on the road

A 110-mile dead zone at 2 p.m. is a missed standup and a dead hotspot. Plan drive days around your call schedule: covered miles for working hours, dark miles for early mornings and evenings.
