Spy Ear: Recorder, Hearing Aid Live

Struggling to hear clearly across a noisy room or crowded space? Poor sound quality and audio drop-outs make most amplification apps unreliable exactly when you need them most. Spy Ear solves this: pair your headphones, point your phone toward the sound source, and get stable, real-time hearing and recording - with a stream that never cuts out. --- HEARING AID + SOUND AMPLIFIER --- Spy Ear turns your Android phone into a portable hearing aid and sound amplifier - no extra hardware, no purchase required.
