Sound Amplifier: Ear Booster

Sound Amplifier uses your phone's microphone to pick up the sound around you, makes it louder and clearer, and plays it straight into your headphones. Follow a conversation in a noisy café, hear the TV without turning it up for everyone, or catch every word of a lecture you are attending. HOW IT WORKS 1. Connect wired, USB or Bluetooth headphones 2. Tap Start listening and allow microphone access 3. Pick a sound mode, then raise the boost until voices are comfortable 4. Lock the screen if you like: listening goes on until you tap Stop FEATURES • Headphones only: never plays through the phone speaker, so no feedback whistle • Boost up to +30 dB and left / right balance • Mute button that keeps your session and replay, plus a sleep timer (15–90 min or when the clip ends) • Simple mode for older users: big buttons and just two sliders, Voice and Background • Remembers your settings for each pair of headphones; one personal sound profile free (a comfort setting) • Fine-tune bass, treble and soft sounds; Table mode; mono sound; play along with music; volume keys change boost • Home-screen widget, 30-day listening history, replay of earlier segments, speech to text on this phone (3 a day) • Instant replay: missed a word?

Analytics and crash reports never receive audio and can be turned off in Settings. PERMISSIONS • Microphone: asked when you tap Start • Notifications (optional): shows a Stop button while listening SAFETY Sound Amplifier is not a medical device and does not replace professional care. Start with your phone volume low and raise it slowly: loud sound over time can damage your ears. Take breaks. Do not use it to listen to or record other people without their knowledge. No account. No sign-up. No ads while you listen.
