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. ## Key features - Real-time variometer with acoustic lift signals - Air traffic awareness with Safesky integration - Thermal Assistant with climb/sink rate visualization - Flight recording with GPS and IGC tracks - Import flights via GPX/IGC - Standalone Apple Watch functionality - Visible takeoff and landing sites ## Pricing and in-app purchases Base price: Free. **Subscriptions** | Subscription | Price | Period | | --- | --- | --- | | 1 year iPhone and Apple Watch | $22.99 | per year | | 3 month Apple iPhone/Watch | $11.99 | per 3 months | | 7 days for Apple iPhone/Watch | $3.99 | per 7 days | ## Recent user reviews (10 of 47) All indexed reviews: https://appshunter.io/ios/app/vario-one/id1605797423/reviews.md ### 5/5 — reagiert schnell auf Feedback & Ideen *2026-06-30* Ich nutze VarioOne zusammen mit der ActiveLook Brille und finde die Kombi fantastisch. Live alle Werte im Blick zu haben, ohne im Thermikkreisen auf das Display schauen zu müssen, ist sehr hilfreich. Ich bin gespannt auf die nächsten Updates und weitere Funktionen. Cool, wenn man direkt Feedback bekommt und dieses so schnell in die Entwicklung fließt. ### 1/5 — De gratuita nada *2025-06-27, version 4.5* Pone que tiene compras dentro de la año pero se tiene que pagar ### 1/5 — Spricht zu spät an *2024-11-01* Habe die App am Startplatz runtergeladen, da ich meinen XC Tracer vergessen hatte. Hat in der schwachen Herbstthermik nicht funktioniert. Unter 1,5m/s Steigen war nur ab und zu ein einzelner Ton zu hören. Darüber gehts dann, aber gerade im Schwachen wäre das Vario nötig. Ich habe ein iPhone 14 Pro Max, da soll der Sensor ja angeblich gut sein. **Developer response:** Hallo Paranaut, hast du im Menü auch den Schalter „verzögerungsfreies Piepsen“ aktiviert? Standardmäßig ist dieser aus! Selbst 0.1 m/s wird dann angezeigt und akustisch ausgegeben. ### 1/5 — Signed me up for an unwanted subscription *2024-10-21* Paid for 1 week’s access to try the app and unknowingly got signed up for a weekly subscription. Scummy behaviour! The vario is too laggy to be useful anyway ### 5/5 — Sehr zu empfehlen, besonders für Anfänger *2024-10-15* Sehr gut um Flugdaten aufzuzeichnen und im Logbuch zu verwalten. Starterkennung funktioniert super, somit kann die App einfach im Hintergrund laufen. Flüge lassen sich dank dem Logbuch einfach nachweisen und verwalten. Beispielsweise kann die Leitlinien-Acht anschließend über die Kartenansicht kontrolliert werden. ### 5/5 — Genial *2024-09-29* Absolut perfekte App für gelegentliches Fliegen bei dem man nur das Tracking benötigt. Sogar die Unterstützung der ActiveLook Brille funktioniert. So erhält man quasi alleine mit einer Apple Watch alle funktionen eines Varios. Eine grafische Komponente zum finden und zentrieren von Thermiken wäre noch wünschenswert. ### 5/5 — Lo mejor y simple de usar. *2024-09-23, version 4.2* Me encanta la app. La última mejora de subir track al XContest facilita mucho el proceso. Por poner solo una pega, me encantaría que pudiera tener sonido diferente para marcar el descenso, como lo tiene el blueBip por ejemplo! Gracias !! ### 4/5 — Retour d’expérience *2024-08-05* L’application fonctionne bien de façon générale. Un peu de latence entre la montée réelle et le premier bip, mais pas beaucoup plus qu’avec un Vario classique. Les traces sont propres, et le carnet de vols est très pratique. Par contre : - sur Apple Watch Ultra, le volume minimum pour le bip est enorme ! Il faudrait un niveau intermédiaire entre « pas de son du tout » et le volume 1 actuel. - sur l’iPhone, pourquoi faut-il « réveiller » le Vario pour consulter le carnet de vol ? C’est pénible de simplement vouloir consulter ses vols et entendre le Vario qui bip alors que je me trouve dans le canapé . **Developer response:** Bonjour Zeromhz, Merci beaucoup ! Le volume peut être réglé dans l'application et aussi sur la molette de l'horloge. Si tu tournes la molette de l'horloge, tu es sûr d'obtenir un volume plus faible 👍 ### 5/5 — Top *2024-05-15* Sehr gute App - übersichtlich, leicht zu bedienen und sehr präzise. Zudem ein sehr faires Abomodell! ### 5/5 — Mega Klasse ! *2024-04-03* Ich flog bisher mit Skytraxx 3, hab mir nun das 5er geholt , und bin durch Zufall auf Vario One gestoßen . Mit nem iPhone und der Apple Watch Ultra eine Mega coole Kombination ! Die Engo Brille 2 hab ich mir auch dazu geholt und bin echt zufrieden ! Mit der Anzeige in der Sonnenbrille, das ist absolut futuristisch , und funktioniert hervorragend . Vielen Dank für diese tolle App , mehr braucht man nicht ! ## Frequently asked questions about Vario One ### What is Vario One?
