FartMania is a joke application that allows you to simulate the emission of "fart" or "big fart" in various ways. Other the simple button, there is function "motion" which, adjusted to your liking, can output the "nice sounds" with the smartphone movement. Another possibility is the "vox" that permit the issue of farts if the level of an ambient sound has passed the set threshold or, conversely, it has dropped below the set threshold.
In practice it is the technological version of the legendary "whoopee cushion"
since version 2.0 it has a new feature that allows you, via Bluetooth, control the emission of farting on a second device connected.

Note: the required permission for the audio recorder is only to allow the activation of the fart via microphone. With this application, no track, of audio recording, is saved!
