Wrist Vario is a fully on-watch variometer and altimeter for Wear OS, featuring:

- Real-time barometer- or GPS-based altitude & vertical-speed (“vario”) readings
- Configurable gauge in dark or light style with selectable scale & units
- Flexible audible tones and vibration feedback as vertical speed indication
- Automatic sea level pressure calculation before take off
- On-screen data (optional): time, battery, GPS accuracy, barometric sensor frequency, air pressure, averaged lift/sink for given period, ground speed or airspeed (respecting wind direction), wind speed
- Ground-speed, bearing compass and wind speed visual indication
- Bezel & gesture controls for in-flight adjustments

Customizable, glance-friendly instrumentation right on your wrist. Supports not only new devices with high accurate GPS and barometer, but also old watches without barometer or GPS - less accurate but still helpful.

Bezel rotation - value change by single point

Detailed description of available parameters:

> Vario Mode

Choose how vertical speed (“vario”) is measured:

Barometer only – uses air pressure to detect climbs and descents.

Mixed – blends barometer and GPS when both are available.

GPS only – relies solely on your phone’s location signals.

> Speed Mode

Decide what speed to show and hear:

Off – no speed displayed.

Ground speed – shows how fast you’re moving over the ground.

True airspeed – adjusts ground speed by wind to estimate your actual airspeed.

> Wind Mode

Control how wind information appears:

Direction only – arrow shows wind direction.

Simple – arrow plus a basic wind indicator.

Detailed – arrow plus numeric wind speed.

> Sea-Level Pressure

Sets the barometer’s reference pressure so altitude readings stay accurate. If you fly in different weather, you can tweak this to calibrate.

> Vario Units

Pick your preferred units for vertical speed:

m/s (meters per second)

ft/min (feet per minute)

> Vario Scale

Choose the vario gauge’s range (the maximum climb/descent it shows):

±5 m/s, ±10 m/s, or ±20 m/s.

> Ground-Speed Units

Select how ground speed is shown:

km/h, mph, or knots.

> Needle Smoothing

Smooth out the gauge needle’s movement. A higher value makes the needle less jumpy but reacts more slowly.

> Digital Smoothing

Same as needle smoothing, but for the numerical vario readout.

> Tone Thresholds

Set the “sink tone” and “lift tone” cut-off points—when the audio alarms start as you sink or climb.

> Volume

Adjust the vario sound volume from silent to loud.

> Vibration

Turn on or off vibration feedback and choose its strength.

> Display Style

Toggle between a light or dark gauge background to suit your environment.

> Brightness

Control the overall screen brightness.

> Info Opacity

Adjust how transparent on-screen info (like altitude, accuracy, battery level) appears.

> Screen Rotation

Lock the app’s orientation or let it auto-rotate so it always faces you.

> Sensor Speed

Balance update speed versus battery life:

Battery-saver – slower, fewer updates.

High-performance – faster, smoother updates.
