## Description

Hear better in the moment. No ads, no subscriptions, no catch.<br><br>ampliPhone turns your Android phone into a personal audio amplifier. It captures ambient sound with the microphone and sends it amplified to your Bluetooth headphones, like a digital hearing aid you already have in your pocket.<br><br>WHAT IT&#39;S FOR<br><br>— Hear a face-to-face conversation better<br>— Follow a conversation in a restaurant or noisy environment<br>— Listen to the TV from the couch without turning up the volume<br>— Understand better in meetings, conferences, or religious services<br><br>HOW IT WORKS<br><br>Choose the microphone you want to use:<br><br>- Headphone microphone — uses the microphone on your Bluetooth headphones. Low latency (~40–100 ms). Ideal for face-to-face conversations.<br><br>- Phone microphone — uses the microphone on your phone. Full stereo sound. Ideal for placing your phone close to the sound source (TV, speaker).<br><br>Choose a scene based on your environment: Neutral, Street, Quiet, Bar, or Meeting. Adjust the volume, 6-band equalizer, voice boost, and balance until it sounds exactly how you want it. Everything is saved for next time.<br><br>WHAT&#39;S INCLUDED, AT NO EXTRA COST<br><br>✓ Amplifier with gain control up to +20 dB<br>✓ Preset environment scenes (Neutral, Street, Quiet, Bar, Meeting)<br>✓ 6-band graphic equalizer (125 Hz to 4 kHz)<br>✓ Voice boost (+4 dB at 2.5 kHz for improved intelligibility)<br>✓ Left/right balance<br>✓ Headphone battery level indicator<br>✓ Audio limiter to protect your hearing<br>✓ Works in the background with visible notifications<br><br>TOTAL PRIVACY<br><br>ampliPhone doesn&#39;t record anything. Audio is processed in real time in your phone&#39;s memory and discarded instantly. The app does not have internet access permissions — this is not a policy, it&#39;s a technical restriction verifiable in the source code.<br><br>Your configuration settings are only saved on your device.<br><br>VOLUNTARY DONATION<br><br>If you find the app useful, you can buy the developer a coffee directly from the app. No pressure, no minimum amounts, completely anonymous.<br><br>IMPORTANT NOTE<br><br>ampliPhone is a sound amplification tool, not a medical product. It is not a substitute for a hearing aid prescribed by a specialist. If you have significant hearing loss, consult an audiologist.<br><br>Developed by holon.es — Custom software, born from the problem.
