SPLWatch - measure sound pressure (dB SPL) levels and audio spectrum frequencies as picked up by the microphone on your Android Wear watch.
Very loud dB levels cause the animated frequency bars to turn red, and the wear device (watch) will vibrate as a warning.
Each animated frequency bar is centered on ISO Octave frequencies: 31, 63, 125, 250, 500, 1k, 2k, 4k, 8k and 16k Hz.
The frequency of the loudest detected sound is shown.
Use long press on the watch face to exit SPLWatch.
Fix so that app actually installs on the Android Wear device (watch) as well as on the 'phone!
