Aufwind vs Variometer+

Aufwind: (noun, German) an upward current of air, updraft. A good preparation is crucial for a safe, relaxed, fun, successful cross-country flight. Overlay all relevant information like airspaces, NOTAMs, waypoints and weather on the map and plan your task for the day with the easy to use visual task planner.  Export the task as a CUP file to an SD-card or mail it to yourself and load it up into your flight computer (LX, Oudie and others) or XCSoar. Soaring Weather: Aufwind comes with most crucial soaring forecasts already built-in: - Thermal strength - Cumulus cloudbase - Rain - Wind To get even more detailed soaring forecasts, you can login with your SkySight account in the app. Task Planner: Plan your task for the day interactively on the map overlaid with the weather forecast, airspaces and other relevant information. Thousands of waypoints are already built into Aufwind but you can import your own as well. You can export the planned task to an SD-card or email to use with your on-board flight computer or XCSoar. Airspaces & NOTAMs: Keep on top of local airspaces and NOTAMs and increase flight safety. Airspaces for many countries are already built into Aufwind but you can also import your own airspace files in OpenAir format into the app. ------------------- Aufwind is free to download and free to use. Some features do require a valid subscription. If you choose to upgrade to Aufwind Pro Subscription, your Apple ID account at the confirmation of purchase or at the end of the free trial period, if offered. Your Aufwind Pro Subscription automatically renews unless unless it is canceled at least 24 hours before the end of the current period. Your account will be charged for renewal within 24 hours prior to the end of the current period. The subscription is offered in yearly period. The price per period will be shown for all subscription options in the app before you confirm purchase or start your free trial, if offered. Aufwind Pro Subscription enables you to overlay weather data on the map for both built-in weather and SkySight forecast (with SkySight account login). You can manage and cancel your subscriptions by going to your account settings on the App Store any time after purchase. Any unused portion of a free trial period, if offered, will be forfeited when you purchase a subscription.

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.
