Offline World Map

← All features

A whole planet in your pocket — no servers required

Most map apps fall apart at 10 000 m. They cache a few tiles in advance, then go blank the moment you cross a coastline. Skyty takes the opposite approach: the entire world map is bundled inside the app, as a single ~46 MB Protomaps PMTiles file. From the second you tap the icon, every coastline, every continent, every major city is already on your phone.

How it works

We use MapLibre Native — the open-source GPU-accelerated successor to Mapbox GL — to render vector tiles directly from a local PMTiles file. Vector tiles are tiny but render crisp at every zoom level, and there is no per-load fee, no API key, no rate limit. Just your phone drawing pixels.

Four themes for every kind of flight

• Aviation Dark — a cockpit-style dark theme with glowing country borders. Perfect for night flights.
• Aviation Light — high-contrast daylight view, easy on the eyes when sun pours through the window.
• Satellite — imagery layer for spotting coastlines and big landmarks at altitude.
• Topographic — shaded relief, ideal over mountain ranges.

HD map pack (optional)

For travelers who want city-level detail, the World HD pack (~3.4 GB) extends the bundled map up to zoom 10. Download once on WiFi at home; it lives on your device forever. Smaller packs for individual continents are coming.

Why it matters

Modern flights are full of moments where you wonder where am I? — a strange coastline, a chain of islands, a desert at sunset. With WiFi you’d Google it. Skyty just shows it. No popup, no spinner, no “no connection.”
