Sound Amplifier: Hearing Aid

Hear Boost transforms your device into a super hearing aid that amplifies sounds up to 200x. Whether you're in a lecture hall, crowded café, or just want to hear conversations more clearly — this sound amplifier puts you in control. Amplify What Matters: Use your phone's microphone or connect any external mic to capture and boost audio in real-time. The live microphone feature lets you hear your surroundings with crystal clarity, while the built-in equalizer helps you fine-tune frequencies to match your hearing preferences. Record Without Limits: Capture lectures, interviews, nature sounds, or anything worth saving. Background recording keeps the app working even with your screen off — no interruptions, no time limits. Recording stops only when you say so or your storage runs out.
