Swiss Vario

Now with BLE vario support for BlueFlyVario, XC Tracer, FlyBeeper and Stodeus — plus Apple Watch, Even Realities G2 glasses HUD, and SeeYou / XCTrack task import.

Swiss Vario turns your iPhone into a real flight instrument for paraglider and hang glider pilots. A precise barometric variometer with configurable audio tones. Live GPS tracking to LiveTrack24, Skylines and Loctome. Real‑time OGN traffic. Airspace overlays for 40+ countries. Apple Watch companion. Even Realities G2 smart‑glasses HUD. Everything a free‑flight pilot needs, in one app that has been in pilots' pockets since 2009.

VARIOMETER

Built‑in audio‑tone variometer driven by the iPhone's barometric sensor, with configurable base and max climb frequency, sink alarm, and beep rate.

Prefer an external unit? Swiss Vario connects to Naviter Oudie N / Omni, BlueFlyVario, XC Tracer, FlyBeeper mini BT and Stodeus BlueBip / UltraBip over Bluetooth for even higher‑precision altitude and climb data.

LIVE TRACKING

Broadcast your position in real time to LiveTrack24, Skylines or Loctome so friends and family can follow along. Configurable update interval; automatic post‑flight IGC upload to Leonardo (OLC), XContest or Highcloud after you land.

TRAFFIC AWARENESS

See other flying pilots on your map in real time via the Open Glider Network (OGN). FLARM‑equipped gliders, FANET beacons, and paragliders tracked through cellular apps — all displayed with per‑aircraft‑type silhouettes so you can tell a glider from a paraglider at a glance.

AIRSPACE

Free OpenAir airspace overlays for more than 40 countries, sourced from the SoaringWeb community. Color‑coded by class, with distance‑to‑airspace calculations and configurable filters so only the classes you care about clutter the screen.

APPLE WATCH COMPANION

Independent watchOS app with a full vario gauge that mirrors the iPhone display — altitude, vertical speed, ground speed and max climb. Toggle the tracker from your wrist without touching your phone; a HealthKit workout session keeps the app alive for the duration of your flight.

EVEN REALITIES G2 SMART‑GLASSES HUD

Native support for the Even Realities G2 heads‑up display. See altitude and vario directly in your field of view during the climb so your eyes never leave the sky.

TASK IMPORT

Point the camera at a QR code from SeeYou Navigator or XCTrack to import task turnpoints in a single scan.

AGL HEIGHT

Real‑time above‑ground‑level altitude computed on‑device from bundled SRTM elevation data. No network required — works in the middle of nowhere.

PRIVACY

Swiss Vario runs no servers of its own. No analytics, no advertising SDKs, no crash‑reporting SDKs. Data leaves your device only to the third‑party tracking services you explicitly configure. Full policy: github.com/petergreis/Privacy

REQUIREMENTS

• iOS 26 or later • Location Services (required) • A barometer‑equipped iPhone for the internal vario (or an external BLE vario) • Optional: Apple Watch, Even Realities G2 glasses

Originally released in 2009 as LiveTrack24Lite, later renamed LiveTrack 24, and now — with a substantial rewrite for 2026 — Swiss Vario. This version marks the biggest release in the app's 17‑year history.
