Altitude uses the pressure sensor in your Android device to provide altitude and rate of climb information displayed on replica analog aviation instruments. Switches are provided to turn on / off the audio and sink alarms as well as a QNH knob to adjust the sea level pressure setting. The QNH knob is dragged around the outside of the instrument dial rather than "turned" for ease of use on a touch screen.

The altitude is calculated using the barometric formula and is reasonably accurate against a mechanical altimeter up to around 10,000 feet. The variometer uses a simple scalar Kalman filter to help stabilise the needle. A future enhancement will be to implement a matrix based filter to improve the responsiveness of the varometer.

Altitude has been tested whilst soaring in sailplanes and paragliding, and is about half a second response slower than a dedicated hardware variometer but never the less provides a very usable vario.

Whats new

    Added support for rate of climb in feet per minute and qnh set in inches of mercury.
    Moved units selection to on-screen button as more devices have no menu button. Hopefully fixed a bug or two.

Simple, very easy to use. Perfect for basic vario information when flying.

Simple clean and works Better sensitivity stability and responsiveness than others. Simple clean and works.

Nicely designed, simple little app This is a nicely designed, simple little app with intuitive controls. I don't fly anymore -- I just wanted a way to play with the barometric pressure sensor on my new phone -- but this seemed to work perfectly, and the price was right. Woo hoo!

Can't set barometric Very wrong because you can't set the barometric preasure but it looks good if u could change the barometric pressure accurately it would be 5 stars
