ampliPhone

Hear better in the moment. No ads, no subscriptions, no catch.

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.

WHAT IT'S FOR

— Hear a face-to-face conversation better
— Follow a conversation in a restaurant or noisy environment
— Listen to the TV from the couch without turning up the volume
— Understand better in meetings, conferences, or religious services

HOW IT WORKS

Choose the microphone you want to use:

- Headphone microphone — uses the microphone on your Bluetooth headphones. Low latency (~40–100 ms). Ideal for face-to-face conversations.

- Phone microphone — uses the microphone on your phone. Full stereo sound. Ideal for placing your phone close to the sound source (TV, speaker).

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.

WHAT'S INCLUDED, AT NO EXTRA COST

✓ Amplifier with gain control up to +20 dB

TOTAL PRIVACY

ampliPhone doesn't record anything. Audio is processed in real time in your phone's memory and discarded instantly. The app does not have internet access permissions — this is not a policy, it's a technical restriction verifiable in the source code.

Your configuration settings are only saved on your device.

VOLUNTARY DONATION

If you find the app useful, you can buy the developer a coffee directly from the app. No pressure, no minimum amounts, completely anonymous.

IMPORTANT NOTE

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.
