Variometer+ is the most responsive variometer for your iPhone or/and Apple Watch. Works for all activities (paragliding, hang gliding, aviation, ...). • Super reactive / responsive thanks to a very advanced algorithm • Beeps like a real variometer (or haptic feedback on your wrist) • Shows ground speed & altitude (sea level & relative to take-off) • Sink alarm • Entirely configurable (settings sync with Apple Watch through iCloud) • Choose among several gauges • Change units (m/s, ft/min, ...) • Customize beeps tresholds • Customize gauge max & min values based on your activity • Customize the sound of your vario (frequency, cadence, ...) for maximum comfort • Independent Apple Watch app (sound, haptic feedback, ...) → everything on your wrist • ... and more Use at your own risk. The creator cannot be held responsible for any issue that might arise. Common sense should prevail. Fly safe! This app respects your privacy and does not collect any data. Feedback is welcome and appreciated, you can contact me from within the app :-). Please be nice with me ;-). About the algorithm: This variometer is not an ordinary app. To provide this level of responsiveness, a very advanced mathematical technique is being used. This is called ‘Sensor fusion’. It uses data from multiple sensors of your devices, and combines them to increase accuracy and responsiveness. This has been developed in collaboration with researchers from the university of UCLouvain in Belgium. Because of the efficiency, hence complexity, of the algorithm, a great amount of computational power is required. This is why, based on the tests, the advanced level of responsiveness is only available on recent devices. The app still works - but is less responsive - on older devices though.

I only wish there was an option to display speed in knots, as this is the common speed unit used in aviation. ### 5/5 — Great *2026-06-01* Thank you for your work and support our community ### 5/5 — Love it *2026-01-17* Love this! Thank you for building it. It works great and saves me a lot of money ### 2/5 — Not reliable, inaccurate *2025-12-02* Inaccurate. When my phone is stationary, this vario app jumps around a lot. Please add the ability to get data from a bluetooth vario (for those that have a screen less device like Stodeus or BlueFly) instead of the using the phone's limited sensors (phone us far less accurate). ### 5/5 — Awesome app *2025-08-27* Easy to use. Just wish I could have a flight log of my flight, to see height gained,climb rate,etc after the flight. **Developer response:** Thanks for your review, for flight log, check out www.wingmanfly.app 🪂⛰️☀️ ### 5/5 — Perfect! *2025-05-23* works totalky fine and reliable. i love the simplicity if the app, thank you so much! can you do gps recording for a one time payment? 😉 **Developer response:** Thank you! For GPS recording, check out www.wingmanfly.app 🪂 ### 5/5 — Simple, parfait pour débuter *2025-05-04* Application simple et gratuite (sans pub !) Fonctionne très bien sur iPhone 13, je débute et je ne peux plus m’en passer, j’hésite à acheter la version pro, mais je voudrais comparer avec un vario dédié avant. ### 5/5 — Worked great with my watch *2024-12-29* Flew today in light conditions using it on my watch. Responded to weak surges with sound and haptics. I look forward to using it while giving instruction in club gliders that just have mechanical varios. ### 5/5 — Great app. *2024-08-03* Is there a variety of raion for WatchOS? I’m gonna check for that. ### 5/5 — Fantástico para Apple Watch. *2024-03-24* Melhor app para Apple Watch porque não precisa do celular. ## Frequently asked questions about Variometer+ ### Does Variometer+ have ads?
