With nearly million iphone apps, I still can't find a simple audio vario app, one which can be used as a backup if all else fails or when flying gliders with mechanical varios. Non compensated and based only on GPS altitude, but still better than nothing. Graphic display optional. Any iphone app developers out there? Should be a simple app.

This one for android with a trace:

The same app is available for the iphone, but after reading the description it sounds like it is not using GPS altitude but using the camera instead to read the vario needle movement, or something strange like this. Maybe useful for someone who wants to add sound to mechanical vario, but not useful as a backup.
