## Headline
Introducing MapMap Nav: offline-first turn-by-turn navigation, built on MapMap in days — and yours to fork.

## Standfirst
We built a complete navigation app on our own platform to prove a point:
everything a modern nav product needs is one API away. MapMap Nav runs on
iOS and Android from a single Expo/React Native codebase, and the whole
thing is open for you to download, test, and build on.

## Body

**Why we built it.** The fastest way to show what a maps-and-routing
platform can do is to ship a real product on it. So we did — a polished,
twelve-screen navigation app with turn-by-turn guidance, voice, search,
route alternatives, and the features drivers actually expect.

**What's in it.**
- **Real maps, your brand.** MapMap vector tiles, styled with MapMap Studio,
  rendered natively at 60fps — 3D buildings, live POIs, light/dark themes,
  and your logo on the map.
- **Turn-by-turn that talks.** Road-following routes from MapMap's engine,
  spoken guidance, lane assist, rerouting, live ETA, and a chase camera.
- **The differentiator nobody else demos in two taps: truck & ADR.** A
  lorry profile where vehicle dimensions and dangerous-goods rules shape the
  route — low bridges, weight limits and ADR tunnel categories avoided, not
  filtered out afterwards.
- **Tap to go.** Tap anywhere to drop a pin and route there; save Home and
  Work; avoid tolls, motorways or ferries; see where you can reach in ten
  minutes.
- **Offline-first.** Signed, verified territory packages keep navigating in
  airplane mode. No tracking — navigation happens on the device.

**Built the honest way.** MapMap Nav uses only our published SDKs and public
docs — exactly what any customer has. Building it surfaced the rough edges,
and we've been fixing them in the open.

**Yours to build on.** Download it, run it, read how the React Native bridge
works, and fork it as the starting point for your own product. A competent
RN team could ship a branded nav app in a fortnight on top of it — that's
the whole idea.
