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:
▶ PLAN AHEAD: Check detailed weather conditions (emagram) over days for your safety, in Europe. Check surroundings and thermal hotspots on the topographic outdoor map.
▶ PLAN LANDING: Set a marker e.g. at the landing area and get assistance when approaching.
▶ 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. Select a pre-defined setting profile matching thermal conditions.
▶ 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.
▶ FIND LANDING: At e.g. a new site, locate the marked landing zone.
▶ REVIEW TRACK: Visualise the past track on 4 map styles or show the track elevation profile graph in animated or interactive mode.
▶ MANAGE LOGBOOK: Access each individual track record time stamped file, synchronise them with your iCloud. Personalise eVario to contain glider/user information.
▶ DO MORE: Re-Play your 3D flight e.g. in GoogleEarth, Analyse flight metrics in BaseCamp.

▶ Clear dashboard of digital real time data
▶ Advanced interactive cockpit with configurable measurement field display
▶ Access a large number of settings directly impacting sensoric, display, acoustic or interaction

▶ Manage/Share track files from within integrated file browser

▶ Visualise your position, track line, thermal hotspots, sites, weather data on map
▶ Map enhancement by overlaid instruments like altitude, speed or ascent
▶ Map style selection: choose from 4 styles including terrain (dark/bright), topo and satellite
▶ Offline map downloads worldwide! Including topographic data, peak names and heights
▶ Unlimited map downloading for offline use (saves mobile data)
▶ Waypoint setting

▶ Bar graph for vertical ascent/descent with peak hold functionality
▶ Visualise current and last track elevation profile versus time
▶ Visualise altitude on graph

*Supported Languages
▶ English, French, German, Spanish, Russian

  • What’s New

    Thanks to your feedback, this version includes:

    **Major Feature**
    ▶ Important! Battery consumption is dramatically reduced and drains are prevented. Follow instructions (Notifications) within App.

    **Top Features**
    ▶ Significant performance improvement in sensor data processing
    ▶ Improvement of waypoint approach tracking and related algorithms

    ▶ Fix for minor issues

    **Continued Benefits**
    All onboard! No need for additional hardware; Sensibility/Response of built-in sensors (Bosch) is reliable for thermalling (preventing volatility)
    GPS gyrometer accelerometer barometer magnetometer assisted variometer
    Connected variometer for up-to-date airspace neighbourhood (OGN/FLARM), live-tracking, map and weather (map) data
    Pre-defined variometer thermalling profiles
    Visualisation of flight elevation profile and track metrics
    Automatic and manual barometer calibration
    Uncluttered cockpit and map
    Highly configurable and interactive cockpit
    Adaptable instruments on a moving map
    Flight heading orientation of moving map
    Display of flight sites including details on map
    Display of thermal hotspots on a moving map
    Flight navigation assistance incl. vocal announcements
    Airspaces monitoring and warnings
    Surrounding aircraft monitoring and warnings on approach
    Stable application and track recording
    Continued measurements in background mode (persistent use of real-time location updates)
    Free of interference by incoming/outgoing calls, messages, notifications, etc
    Support of iCloud/iTunes for track records exchange/saving

    ▶ Automatic Location-based Tracking – The eVario way!
    ▶ Automatic Location-based Assistance – The eVario way!
    ▶ Accurate location movement detection and monitoring, thanks sensor fusion
    ▶ Simple to use visualiser and recorder! Turn On & Go! Easy to understand and operate for newbies as well for experts
    ▶ Vocal announcement of approaches
    ▶ Concentrate on your adventure

    Continued use of GPS and/or accelerometer running in the background can dramatically decrease battery life. eVario was designed to use GPS very sparingly, but supports background usage for continued tracking. This was chosen wisely to maintain best experience. If you experience significant battery drain while using eVario, select the power save mode in the device’s Settings menu or deactivate energy consuming instruments.

    100% Private: Only YOU can see your data. We will never collect or share any information about you. We really respect and take care of our users privacy!
    By activating the OGN feature you share your location data for live tracking

    ▶ “I just downloaded eVario and I love eVario! …”
    ▶ “Incredibly well executed!”
    ▶ “… amazingly easy to use.”
    ▶ “I had no idea that my iPhone could do such things!”

    ▶ Uncluttered interface
    ▶ Automatisms for focused user experience
    ▶ Clean design and extreme simple to use
    ▶ Stable and robust application
    ▶ Pretty intuitive design
    ▶ No pointless gimmicks or useless controls
