NETTRASH.Geo

Point your camera at the skyline and Geo names the peaks you see — with live altitude, a storm-warning barometer and offline peak maps for the trail.

Geo turns your iPhone and Apple Watch into a mountain instrument. Point the camera at the skyline and it names the peaks in front of you; check the Info tab for your exact altitude and the air pressure around you; and let the barometer warn you when the weather is about to turn.

NAME THE PEAKS YOU SEE Hold up the camera in the Nature view and every mountain gets a label — its name and height — pinned to the real summit. Only the peaks actually above your horizon are shown, and a minimum-altitude slider hides the small hills so you can keep just the big mountains. Tap any peak for its distance, bearing and directions. Download an area first and it all keeps working with no signal, out to ~80 km.

KNOW YOUR ALTITUDE Geo reads height from the iPhone's barometric sensor and satellite GPS, and shows how far you are up "% of Everest". Standing at a marked elevation — a trailhead sign or summit marker? Calibrate to it in one tap and every reading, including the widget and the Watch, snaps into agreement.

A BAROMETER THAT WARNS YOU A falling barometer is the classic sign of incoming weather. Geo watches the 3-hour pressure trend — corrected for the altitude you've gained, so an ordinary climb doesn't read as falling weather — and sends a single storm-warning notification when pressure drops sharply. Treat it as one more sign to read alongside the sky, not a forecast: the altitude correction leans on a recent GPS fix, and background timing is up to iOS, so the warning is best-effort.

RECORD THE TRIP Start the trip recorder for total ascent and descent, distance, moving time and an elevation profile. Log the summits you reach in a trophy case. Everything syncs privately across your devices through your own iCloud.

SUN & SKY The Sun panel computes sunrise, sunset, golden hour, blue hour and civil twilight for exactly where you are and how high — no connection needed.

ON YOUR WRIST & HOME SCREEN An Apple Watch app with its own barometric altitude and history, plus home-screen and Watch widgets and complications that show your current altitude at a glance.

PRIVATE BY DESIGN No account. No ads. No trackers. Your altitude and pressure history, trips and summits stay on your device and sync only through your own private iCloud — never to any server we run. The only network calls render the map, look up nearby peak names and ground elevation, and fetch the planetary K index from NOAA, in a request that contains nothing about you.

Requires an iPhone with a barometric sensor for altitude readings; the Nature view needs a device that supports ARKit and a clear view toward the horizon. English only.
