eVario vs Variometer+

eVario is your connected flight navigation companion during and after your adventure trip, helping you to visualise relevant data, assist you while progressing in the air by returning visual and acoustical feedback. eVario is a 9-axis measurement (accelerometer, gyrometer, gps), barometer assisted, connected and intuitive instrument with a polychrom display, exploiting the embedded device’s hardware and accurate sensoric, without need to connect external devices. It typically provides real time information of a variometer like altimeter, speedometer, odometer, chronometer, gyrometer, anemometer for every (air)craft pilot. Its configurable cockpit allows you to keep track of the most relevant to you. The integrated data logger automatically records your 3D location and provides the recorded track file to e.g. your iCloud Drive for track visualisation or flight metrics. Turn on & Fly! No need for additional/external hardware. eVario is mainly designed for paragliding/hang-gliding, but may be used as well while biking, hiking, running, sailing, skiing, flying, … Optimised for low battery usage, the app lets you: ▶ TOUCH&GO: Turn on & Go fly! The cockpit shows real-time data after a short automatic instrument calibration. ▶ TAKE OFF: Automatic track recording is taking place in background and take-off altitude is referenced. ▶ STAY IN CONTROL: Control the behaviour, update rate, unit of the instruments, anytime and anywhere. ▶ THERMALLING: Get acoustical and visual feedback of the encountered thermals and easily locate them when returning back. ▶ BE EFFICIENT: Track wind estimation, direction and force, to soar or prepare your landing. ▶ DO MORE: Review your activity track and metrics in Health app or replay your 3D flight e.g. in GoogleEarth, Analyse flight metrics in BaseCamp. KEY FEATURES *Cockpit ▶ Clear dashboard of digital real time data ▶ Unlimited GPS tracks and waypoints saves ▶ Support of metric and imperial unit system ▶ Support of GPX record formats ▶ Automatic tracking start/stop upon movement detection ▶ Automatic GPS track recording ▶ Logbook with individual 3D GPS track records (timestamp, latitude, longitude, elevation) supporting derived data analysis *Map ▶ Visualise your position on map *Tracks ▶ eVario integrates with Health app to record your track data including eVario specific metric data. ▶ Visualise your flight record in Health app More on the developer's website.

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.
