Need PhoneGap (HTML/JS) "Hearing Aid" app that works for both iPhone and Android devices.
1) App must funnel the sounds picked by the microphone directly to the speakers (earphones actually).
2) App should display a large knob in the middle of the screen, like a hifi button (please see enclosed image for reference). Turning the knob controls the volume of the device. App should also display an on/off button that starts and ends sound processing.
3) Optional: simple sound equalizer or EQ boost of high and low frequencies (to enhance voices).
This is a rush job. Fastest, cheapest bidder wins. Provide me with a working prototype and the bid is yours.
Thank you for your time.
