WIA Gil

Navigation · works without internet

The signal drops. The guidance doesn't.

WIA Gil saves your route on the phone the moment you get it. In a tunnel, a mountain valley or a disaster zone, GPS satellites keep guiding you along it, no data needed. You can even hand the route to another phone as a printed code.

How it works

GPS never needed the internet. The route did.

Your phone hears satellites anywhere under open sky. What a normal navigation app loses offline is the route itself. WIA Gil keeps the route on the phone, so the satellites are enough.

1 · ONLINE

Find a route

The route, turn list and up to two backup routes are saved on the phone automatically. Nothing to tap.

2 · NO SIGNAL

Keep driving

Turn-by-turn voice continues from GPS alone. If you leave the route it says how far and which way to go back. If you are on a backup route, it switches to it.

3 · STILL OFFLINE

Reopen the app

Battery died or the tab closed? The app opens without internet and offers "Continue guidance" on the saved route.

4 · HAND OVER

Give it to another phone

Show the route as a WIA Code, print it, or play it as a WIA Stream. The receiving phone needs no internet to read it.

How to use

Two phones, one route, no network

Your own phone

  1. Open wiagil.com once while you have internet. The app keeps itself on the phone.
  2. Search a destination and start guidance. The route is saved automatically.
  3. Drive. When the signal goes, a small banner says "Offline — guiding with the saved route".

Handing a route to someone else

  1. Tap 📤 Share route. Choose to include backup routes and sign with your account.
  2. Show the map-pin shaped WIA Code on screen, print it, or play the WIA Stream.
  3. The other person scans it with the WIA scanner. WIA Gil opens and starts guiding, even in airplane mode.

Why it matters

Most of the world is not always online

2.2 B

people were still offline in 2025, 96% of them in low- and middle-income countries.

ITU Facts and Figures 2025
300 M

people live where there is no mobile broadband coverage at all, mostly rural and sparsely populated.

GSMA, State of Mobile Internet Connectivity 2025
~4 B

people are estimated to live where streets have no names or numbers, a figure widely attributed to the UN.

Golden time

Emergency and rescue dispatch

A dispatch centre with internet plans the route and hands crews a printed or on-screen code. The crew keeps turn-by-turn guidance through dead zones, tunnels and mountain roads instead of losing minutes to a frozen map. A signature shows which dispatch account issued the route and that nobody changed it.

No street addresses

Arrive at a point, not a street name

The route ends at exact coordinates, with a WIA Pin Code for the destination. Clinics in informal settlements, farms, camps and new districts become reachable without a street address.

Limited internet

Rural, mountain, border and disaster areas

Where coverage is patchy or networks go down after a storm or earthquake, a route prepared once at a town centre keeps working all the way. The receiving phone needs no data plan.

Travel and logistics

Travellers without roaming, drivers without data

A hotel, depot or tour desk prints the route; the visitor or driver follows it in their own language with voice guidance, without buying a SIM or paying roaming.

Where the economic value comes from

  • Zero data to receive. A route costs about 1 KB per 100 km and can travel on paper, so the receiver spends nothing on data or roaming.
  • Fewer failed trips. Deliveries, home visits and pickups in places without addresses stop depending on phone calls and landmarks.
  • Minutes back in emergencies. Guidance does not stall at the moment coverage disappears, which is often exactly where help is needed.
  • No new infrastructure. It runs on phones people already own and on GPS that is free everywhere. A printer is the most expensive part.

We do not publish savings figures yet. Pilot partners will measure arrival time, failed trips and data cost before and after.

Honest limits

What it does not do offline

It cannot plan a brand-new route if you go far off the saved and backup routes. It guides you back instead.

It does not know live traffic or road closures that happen after the route was made.

Map imagery may not load; the route line and your position always show.

Each phone must open wiagil.com once with internet. GPS needs a view of the sky.

A signature proves which WIA Gil account made the route and that it was not changed. It does not certify an organisation.

The route stays in the link after the # sign and is never sent to our server.
