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.
Features:
Sound amplifier with up to 200x boost
Live mic monitoring with adjustable gain
Voice amplifier mode for conversations
Built-in sound equalizer to enhance or reduce frequencies
Works with internal, external, or Bluetooth microphones
Background recording with screen off
Noise canceling filters for clearer audio

Who Is It For?
Students recording lectures. Journalists capturing interviews. Anyone with mild hearing difficulties who wants a portable hearing aid alternative. Or simply the curious who want to explore super hearing and spy hearing capabilities.
Heads Up
Use headphones for the best experience. Without them, the microphone picks up speaker output and creates feedback. Any wired or Bluetooth headset works perfectly.
