Digital Hearing Amplifier
A fair question before trying any app that keeps the microphone running: what does it do to your battery? Short sessions of real-time audio processing cost less than people usually assume — here's roughly how it compares to other everyday phone tasks.
- Not a hearing aid
- No account needed
- Short, timed sessions
- iPhone & Android

Figures are rough, commonly cited approximations for illustration across typical phones, not a benchmark of this specific device or app version.
What it does
Built around what actually helps
Voice separation
Speech gets pulled forward relative to background noise, instead of the whole recording getting louder together.
Three-band EQ
Bass, voice, and treble adjust independently, since a fixed profile suits nobody exactly.
Loud-sound cap
Sudden spikes get capped automatically rather than blasting through at full amplified volume.
No processing lag
Runs live on the device, with no noticeable delay between speech and hearing it amplified.
Offline by default
No connection required to amplify, which is part of why it's lighter on battery than tasks needing constant network use.
Shared subscription
Up to 4 devices on one Premium plan via QR code.
How it works
Three steps, no account required
Connect headphones
Wired or Bluetooth, whatever's already around — nothing new to buy first.
Aim the phone
Toward whoever's talking, or toward a speaker — amplification follows the direction it's pointed.
Adjust the level
Plus and minus controls appear the moment amplification starts, with the EQ one tap away.

Questions about digital hearing amplifiers
Will this drain my battery fast?
Not dramatically for typical short sessions. Real-time audio processing is lighter than tasks combining GPS, camera, and constant network use, like navigation or video calls.
Is this a hearing aid?
No. It's a general sound amplifier, not a regulated medical device, and not fitted to a diagnosed hearing loss.
Why does it need headphones instead of the speaker?
Playing amplified sound out of the same phone that's recording it creates feedback. Headphones avoid that loop entirely.
Is the free version actually usable?
Yes — three real listening sessions of 15 seconds each, every day, with no account required.
Does it need an internet connection?
No. Amplification runs entirely on the phone. A connection only matters for the download or an optional subscription.
Is any audio recorded or stored?
No. Sound passes through the app in real time and is never recorded, saved, or uploaded.
Can I share one subscription with family?
Yes — a Premium subscription covers up to 4 devices through a QR code.
Does it work on both iPhone and Android?
Yes, with the same core features on both the App Store and Google Play versions.
