Earbeat

Earbeat is a hearing aid app, easy to use & simple in design. It provides amplification of sound of up to 24dB. There are no complications in Earbeat: just push the big white button to start hearing better & louder!

Works in the background too, so you can do other things while you hear amplified sound.

Note: the app must be used with headphones, otherwise it will not work well.
