Plain-language glossary
Four terms people mix up constantly
Personal sound amplifier (PSAP)
This app's categoryThe FDA's own term for a device meant for people with normal hearing who want to amplify sound in a specific situation — hunting, bird-watching, following a distant speaker. Not marketed or intended to compensate for hearing loss. This app falls into this category.
Hearing aid
Regulated medical deviceA device specifically intended to compensate for a diagnosed hearing impairment. Historically required a medical exam or waiver; regulated by the FDA as a medical device.
OTC hearing aid
Since 2022A newer FDA category letting adults with perceived mild-to-moderate hearing loss buy a hearing aid without a prescription or exam — still a regulated hearing aid, just without the exam requirement.
Assistive listening device (ALD)
Broader categoryA catch-all term covering PSAPs, captioning devices, and other tools that help with listening in specific situations, without being medical devices themselves.
This is general information, not medical or legal advice, and reflects FDA guidance in the United States. Rules can differ outside the US.
How it works
Three steps, no account required
Connect headphones
Wired or Bluetooth, whatever's already around — nothing proprietary 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.
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 — the internet only matters for the initial download.
Shared subscription
Up to 4 devices on one Premium plan via QR code.

Questions about personal sound amplifiers
Is a personal sound amplifier the same as a hearing aid?
No. A PSAP is intended for people with normal hearing amplifying sound in a specific situation. A hearing aid is intended to compensate for a diagnosed hearing impairment. The FDA treats them as different categories.
Is a PSAP legal to sell and use without a prescription?
Yes — that's the point of the category. PSAPs are explicitly for people without diagnosed hearing loss, so no exam or prescription applies.
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.
