Offline location journal you own. One tap captures the exact spot — no signal, no account, no cloud. Your memories are open GeoJSON files on your phone, yours forever.
GeoJSONic — offline location journal you own.
Some places you want to keep. GeoJSONic lets you capture them like a journal — written, spoken, and seen — and it all stays on your phone, in the open GeoJSON format, with no account and offline.
Make a note where you're standing and it quietly remembers the context: the coordinates, elevation, the place name, and the weather at that moment. Add a photo (it already knows where it was taken), record your voice, or write it down. A place that's written, spoken, and seen — all on one note and only on your device, instead of some data center owned by a billionaire.
WHEN A SINGLE POINT ISN'T ENOUGH
• Record a route — run, walk, hike, bike, drive, or paddle, and your path draws itself as you move.
• Map an area — a scout, a hunt, a survey, or a round of golf: walk the bounds and GeoJSONic traces the outline, measures the acreage, and lets you drop photos, audio, notes, and lines as you go, each pinned to exactly where you stood. Turn it into a clean PDF field report for a client or your records.
IT'S GENUINELY YOUR DATA
• Everything is plain GeoJSON — the open format the whole mapping world uses. Open your journal in any GIS tool, or geojson.io.
• Back up and restore your whole journal anytime (Settings → Export).
• No account. No servers. No tracking. It lives on your phone.
A FEW MORE THINGS
• Send places straight in — share an address from Apple Maps, or a photo from Apple Photos, and it becomes a note right where it belongs.
• Compass — open a full-screen compass anytime, or get a live heading and distance straight back to any note you've saved. Works with no signal.
