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 iPhone and Apple Watch. Both apps work independently and signal lift with acoustic beeps. Optionally connect an external Bluetooth vario for even more precision. Try all features free for 14 days. VARIOMETER - 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. - Climb tone threshold freely configurable (down to -0.5 m/s). - Rotating wind direction indicator. FLIGHT RECORDING - 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. THERMAL ASSISTANT Your flight track is coloured live by climb and sink values - so you instantly see where the best thermal is in the turn. The app automatically detects circling and switches to the thermal view. Including wind direction and speed. 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. APPLE WATCH - Standalone vario with precise pressure sensors. - Ideal for hike & fly, as a backup or when there's no room in the cockpit. - Flight recording in GPX and IGC format. 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.

Vario One version 7.1
Updated At: 2026-09-11
Changes: Version History • DHV practice record (Germany): Vario One counts your flights from the last 24 months, fills in missing details from your logbook and creates the proof as a PDF.
• DHV sites marked: German take-off and landing sites show the DHV logo, the source of the data and a link to the DHV site database.
• Clearer buddy markers: a compact ring with climb rate and direction; buddies in the same thermal are merged into a single marker. 7.1 6d ago New: Buddy Flying – fly together and see your flying partners live on the map.
- Create a group, share the code, join – as soon as "Sharing" is active, you all see each other in real time.
- For each buddy: position with distance and bearing, altitude absolute and relative to you, climb current and as an 8-second average, plus speed.
- A colour scale instantly shows who just found the best thermal.
Also: minor improvements and bug fixes. 7.0 Jul 31 Translations have been added for all languages 6.6 Jul 3 All-new airspace system, four new external variometers, barometric altitude/QNH, and
more.

• Import your own OpenAir files (classic and Naviter 1.0/2.0)
• All airspace displayed as a vector layer – tap any zone for details, vertical
profile, and legend
• Real-time warnings as you approach airspace – with voice alerts (TTS), configurable
lead time, snooze, and escalation
• Warning system can be toggled on/off
BAROMETRIC ALTITUDE & QNH (NEW)
• Set QNH directly from the flight screen

A variometer belongs in the luggage of every paraglider pilot. Just like a helmet and the glider itself, that's for sure. If only these black blocks weren't such heavyweights - heavy in price, heavy to operate and heavy to carry. How smart would it be to have a variometer directly in your smart device, simply as an app? And one that is as precise and reliable as a professional variometer?
Doesn't exist? Discover VARIO ONE, the smart variometer app, and find out here what VARIO ONE can do:
First things first:
1. You get 2 apps for one price! An app for your iPhone AND the app for your Apple Watch. With both you can fly independently. The climb is indicated on the display by different beeps, just like with other Varios.
2. You do NOT need any other devices. The iPhone from version 12 and the Apple Watch from version 6 have very fine sensors (pressure socket).
FUNCTIONS FOR iPhone App + Apple Watch App. Both apps can:
● Very precise acoustic variometer: due to the high-precision air pressure sensor, a climb is immediately audible. So you can react immediately and make the best possible use of the thermals.
● Frequency pitches and sound volumes adapt to the climb values: this means that even the smallest thermals can be found and you can react to larger ones in a relaxed manner.
● Display of altitude and speed above ground
● The display of the wind direction is rotating: this means that you can see which direction the wind is coming from at your current position. This is how you can avoid dangerous leeward situations
● Record your flights from the Apple Watch or iPhone as a GPS track and automatically upload them to your digital flight log.
FURTHER FUNCTIONS of the iPhone app:
The above features are all in the iPhone app. In addition:
● For your iPhone, the VARIO ONE app includes the ability to view your recorded flights.
● A glide ratio display is of course also included: so you can easily calculate whether you can reach a landing site or another destination, or whether it would be better to look for an alternative early on.
● Switch between white mode and dark mode: depending on your taste and the current lighting conditions.
WHEN IS THE WATCH APP RIGHT FOR YOU?
● Are you a Hike & Fly fan?
● Safety is your top priority and you like to have a second variometer as a back-up?
● Are you looking for a very small vario with high-precision air pressure sensors and a rotating wind indicator?
● You have no more space in the cockpit or don't want to worry about another mount?
● You want to record your flights in GPX format? That's possible too!
------
Advantages over classic Varios:
● Extremely accurate sensors: the built-in GPS and barometer meet the highest precision requirements and easily outperform many hardware devices.
● Constant expansion of the two apps: We still have many ideas for expanding the range of functions and are continuously delivering new features.
● Intuitive to use: the VARIO ONE app is immediately understandable and easy to use. You won't find long and complicated instructions here.
