About this app

VARIO One – Your smart variometer for iPhone and Apple Watch. As precise as a pro vario. As simple as an app. No extra hardware.

VARIO One combines a pressure sensor, an accelerometer and GPS into a full-featured variometer — right on your phone. Works with Android smartphones equipped with a compatible barometric pressure sensor or with a supported Bluetooth variometer.

Try all features free for 14 days.

VARIOMETER

- Variometer performance depends on your Android device's built-in barometer, not on the app. Please use the 14-day free trial to see how well it works on your device. If you're not satisfied, you can connect a supported Bluetooth variometer instead.
- Instantly audible lift by combining pressure and acceleration sensors.
- Internal barometer (baro + IMU fusion) — a calmer, more precise signal.
- Display of altitude, speed and glide ratio.
- Barometric altitude with QNH — set directly on the flight screen.
- Rotating wind direction indicator.

FLIGHT RECORDING

- Automatically generates the DHV proof of practice as a PDF in your digital logbook.
- Automatic recording as GPS and IGC track.
- Digital logbook with map view and statistics.
- Automatic upload to DHV-XC and XContest.
- Automatic take-off and landing detection.

MAP

- Airspaces downloadable per country or importable as OpenAir files.
- Current wind from thousands of weather stations.
- Take-off and landing sites — permanently free to view.

AIRSPACE MAP & ALERTS

Download airspace maps for any country right in the app from OpenAIP. Or import your own OpenAir files (classic as well as Naviter 1.0/2.0). All airspaces are shown as a vector map; tap for details, altitude profile and legend. As you approach, VARIO One warns you with a voice announcement and a configurable lead time — including a snooze function and automatic escalation.

REAL-TIME AIR TRAFFIC WITH SAFESKY

See nearby aircraft — paragliders, hang gliders, sailplanes, helicopters — using SafeSky, including other SafeSky users on the map. ADS-B, FLARM, OGN, PilotAware, and other supported traffic sources — all in one real-time view. Coverage depends on the availability of compatible transmitters and network reception.

BUDDY FLYING – FLY TOGETHER, EVERYONE IN VIEW

With Buddy Flying you see your flying partners live on the map — perfect for a shared cross-country flight or a day at your local mountain. One person creates a group and shares the code, the others join. As soon as "Sharing" is active, you all see each other in real time.

For each buddy you see position with distance and bearing, absolute altitude and altitude relative to you, current climb and an 8-second average, plus speed. When a buddy is climbing, you see it in their climb rate — and know where the thermal is. A colour scale shows how their climb compares to yours.

EXTERNAL BLUETOOTH VARIOS

Connect your device wirelessly to use it as your vario signal source: BlueFly Vario (multiple protocols), Mipfly MipBipX & MipTrack, Stodeus BlueBip & UltraBip, Skytraxx (BLE). Connect any time from the settings — no onboarding needed.

IMPORT FLIGHTS

Import previously flown flights as GPX or IGC files straight into the logbook — via the + button or via "Open with" from the Files app.

NEW FEATURES COMING SOON

New features are added regularly. Try everything free for 14 days. Take-off and landing sites remain free afterwards too. The subscription renews automatically and can be cancelled any time.
