Offline GPS for iPhone and Android. Your exact coordinates, nearest city, and country, in airplane mode, underground, at sea, or anywhere off the grid. A 160,000-place database lives inside the app, so there is nothing to download before you travel. Free, with an optional one-time €2.99 Pro upgrade.

SkyLocation is a commercial, closed-source app. This repository hosts its documentation, release notes, and public issue tracker, not the source code. Bug reports and feature requests are genuinely welcome: open an issue.
Your phone's GPS chip is a receiver. It listens to satellites, so it keeps working with cellular and Wi-Fi switched off, in airplane mode, in a tunnel, on a ship, deep in the mountains. The problem is the apps: most map apps go blank the moment you lose signal, because they need a connection to turn your coordinates into a place.
SkyLocation closes that gap. It reads your raw GPS fix and resolves your nearest city and country entirely on-device, from a database that ships inside the app. No connection, no pre-trip downloads, no account. Open it at 37,000 ft, point at the window, tap once, and you know where you are.
- 🛰️ Coordinates anywhere, offline: exact latitude/longitude, altitude, speed, and accuracy straight from GPS satellites, with the network off.
- 🏙️ Nearest city & country, built in: a 160,000-place offline database turns raw numbers into a readable location. Nothing to download first.
- 📍 Exact Place (Pro): pinpoint down to the village or suburb, not just the closest big city.
- 🌅 Horizon (Pro): sunrise, sunset, golden hour, civil twilight, and moon phase, plus a live compass that points to your saved beacons. All computed offline.
- 🧭 Insights (Pro): timezone, hemisphere, climate, elevation, distance from the equator, and live GPS precision at a glance.
- 🗂️ Private location history (Pro): every detection auto-saved, searchable, and filterable (in-flight / on-ground / favorites). It never leaves your device.
- 🗺️ Interactive maps (Pro): standard, hybrid, and satellite views, plus one-tap open in Apple or Google Maps.
- 🆘 Emergency SOS (Pro): share your exact position when it matters, built for off-grid moments.
✈️ GPS Flight Guide (free): how to get a fix at altitude, and why GPS works when nothing else does.

Different tools for different jobs: Flighty is excellent for flight tracking, Organic Maps and the offline modes of Apple/Google Maps are great for navigation with pre-downloaded maps. SkyLocation is the one that tells you your precise position and place, instantly, with nothing pre-loaded.
The apps collect nothing: no account, no analytics, no tracking, no third-party SDKs. Your coordinates and history are computed and stored on your device and are never uploaded. SkyLocation is Built in Germany and GDPR-ready. Full details, including what the marketing website does differently, are in SECURITY.md.

Is SkyLocation open source? No. It is a commercial app sold on the App Store and Google Play. This repository is its public documentation and issue tracker, not its source code.
Why pay for Pro when free offline map apps exist? Free SkyLocation already gives you exact coordinates plus your nearest city and country offline, with zero setup. Pro (€2.99, one-time, no subscription) adds pinpoint Exact Place, the Horizon sun/moon/compass, private Location History, interactive maps, and Emergency SOS. If you want full offline turn-by-turn navigation, a maps app like Organic Maps is a great free choice. SkyLocation is for knowing exactly where you are right now, especially in the air.
Does it really work in airplane mode with no signal? Yes. GPS is satellite-based and receive-only, so it works without cellular or Wi-Fi. Internet is only ever optional (for example, loading map tiles).
Do you collect or upload my location? No. Everything is processed on-device and nothing is sent anywhere. See SECURITY.md.
If SkyLocation helps you, please ⭐ star this repo. It genuinely helps an indie app get discovered.
