Variometer+ vs Box the Wind

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.

Box the Wind is for flying a balloon competition with a simplified IT layer. Fly, don't fight the computer or app. It's for the pilot in the basket and the crew chasing them. This is a competition-specific ballooning app, not a general one. Its features are focused on what the competition pilot needs, and no more. It is designed to fly next to the BLS and BLA setup and replace a cumbersome IT setup. Load the day's tasks, pick a target, and get live bearing, distance, and closest approach on your current drift. See the contest area, the prohibited zones. Crew sees both the ballon position and theirs. The maps work both online and offline. WHAT'S IN IT • Tasks, shared. Import a WatchMeFly task sheet via URL (web page or PDF), edit it, tap a target to make it active. Marker color, number, and timing sit right in the list. The crew can import the pilot's tasks whenever they change, or run their own version. • The wind cone. Your measured drift by altitude plus a forecast sounding, with an AGL bar showing which level heads toward the target. • Live tracking support for the crew. Position flows pilot to crew over a private channel in real time. A clear stale marker shows if the link drops. The crew's own position shows too. • Declare goals easily. Auto-find the 4/4 from the display center, or key one in during flight, checked against the contest area before you commit. • Zones and warnings. Import Red, Yellow, Blue, and Red-Road zones and the contest boundary. Audible and on-screen warnings fire as you approach or infringe, with per-zone ceilings and floors. • Offline maps. Download street and aerial imagery for your region before launch; it renders fully offline in the air. • Practice mode. Log electronic marker drops and get the 2D or 3D distance to the target. A training tool, not official scoring. • Recording. Every flight logs to GPX — replay, rename, share, or import. ... and more ... Built to BFA/FAI AX conventions: the UTM 4/4 grid, the standard task types. Show units in metric, imperial, or a mixed mode that keeps altitude in feet and distance in meters. Actually, for real, free. No account. No ads. No tracking. Your location is used only to show your position, recording and sharing only when you want. Actively supported and listening to requests.
