Hearing Aid App for iPhone: Which of the Two You Mean

Search “hearing aid app for iPhone” and half the results are apps that control hearing aids you already own. The other half are apps that try to turn the iPhone into one. Google can’t tell which you meant, so it shows you both, and you’re left comparing a Phonak remote control against a sound amplifier as if they were rivals.

They’re not. They’re two different answers to two different situations, and working out which situation you’re in is most of the job.

”Hearing aid app” means two different things

If you already wear hearing aids, the app you want is the companion app from the brand that made them. It adjusts volume, switches programs, and streams calls. There’s nothing to compare, because only your brand’s app will talk to your hearing aids.

If you don’t wear hearing aids, you’re looking for something that makes the phone itself do the work: the iPhone’s microphone picks up the room, and your headphones play it back louder. On an iPhone that’s three things. Apple’s Hearing Aid feature, Apple’s Live Listen, or a third-party amplifier app like Clarive, which is the one I build. Which of the three you can actually use comes down to what’s in your ears.

That second group is where most of the searching happens, and where most of the money gets wasted, so it gets most of this page. If you want the wider map of every kind of app for hearing loss, captioning included, we’ve drawn it in apps for hearing loss: which kind you actually need, and the rest of the comparisons live in the comparisons hub.

If you already wear hearing aids, the app is chosen for you

The brand on your hearing aids decides the app. Phonak aids use myPhonak. Oticon uses Oticon Companion. Signia has the Signia app, ReSound has Smart 3D, Starkey has My Starkey, Widex has Moment or Allure depending on the model. Install a different brand’s app and it will open, look for hearing aids, and find nothing.

What those apps do is broadly the same across brands: volume, switching between programs your audiologist set up, a few sliders for noise or bass, call and media streaming, and a find-my-hearing-aids map. What they don’t do is change the fitting itself. People regularly post on hearing forums that the setting they want isn’t in the app, and the usual reason is that it lives in the clinician’s fitting software, not the phone. If a program sounds wrong, that’s an appointment, not an app update.

On an iPhone there’s a second layer under the brand app, and it’s worth setting up. If your hearing aids are Made for iPhone, the phone can control them directly:

1. Put the hearing aids in pairing mode and hold them near the iPhone.
2. Open Settings, tap Accessibility, then Hearing Devices.
3. When the hearing aids appear, tap the name.
4. Tap Pair on the Bluetooth request. There may be one per ear.

After that, Apple’s own Hearing Devices controls let you adjust the microphone level and presets from the iPhone and stream audio to the aids without opening the brand app. Not every hearing aid supports it. Apple keeps a compatibility list, and the model number on your aids is what to check it against.

Live Listen also works with MFi hearing devices, which makes it the cheap remote microphone people keep asking about. Put the iPhone on the table near whoever’s talking and the audio goes straight to your aids. That’s the whole trick, and it costs nothing if the hardware qualifies.

If you don’t, three things make an iPhone act as the hearing aid

Here’s the comparison nobody on the first page of results puts in one place. What matters is the second column.

Apple’s Hearing Aid feature is the most capable of the three and the most gated. The FDA authorized it in 2024 as an over-the-counter hearing aid, which is a real regulatory status the other two rows don’t have. It’s also locked to two earbuds, an age, a range of hearing loss, and one noise mode. If you clear those four gates, it’s the thing to try first, and I’d rather you bought AirPods Pro than paid me a subscription. The requirements are in Apple’s own instructions, and we’ve been through them gate by gate in what Apple’s hearing aid feature is and who gets it, plus what the lab tests actually show for how much it delivers.

Live Listen is the oldest of the three and the least demanding on the phone. It turns the iPhone into a remote microphone. The limit is the receiving end: Apple only sends it to AirPods, some Beats, and MFi hearing devices. Your wired EarPods, your Sony earbuds, your gym headphones: none of them can receive it, and there’s no setting that changes that. Every workaround people suggest is in Live Listen without AirPods. Short answer, none of them work.

An amplifier app is what’s left when the hardware gates shut you out, and the reason it works with any headphones is a plumbing detail: it uses the ordinary audio output path every app uses, the same one your music goes down. Live Listen and the Hearing Aid feature go through Apple’s own hardware channel, which is why they’re restricted and apps aren’t. What an app gives up in exchange is everything on the right of that table. It amplifies. It doesn’t measure you, it can’t touch phone calls, and it isn’t a hearing aid however it’s named on the App Store.

What an amplifier app is, and what it isn’t

The App Store is full of apps called Hearing Aid, and Clarive uses the phrase in its own listing too, because it’s what people type. So here’s the honest line, and it’s the FDA’s, not mine.

A hearing aid is a regulated device intended to make up for impaired hearing. A personal sound amplification product is intended to make sound louder for people with typical hearing in specific situations, a lecture from the back row, a quiet talker across a table. The FDA draws that line on intended use, not on the technology inside. An app that makes the room louder sits on the amplifier side of it. Calling it a hearing aid in the name doesn’t move it across.

That matters for what you should expect. A fitted hearing aid is shaped to the specific pattern of your hearing: which frequencies you’ve lost, how much, in which ear. An amplifier app has no idea what your hearing looks like. It raises the volume of whatever the microphone hears and, in the better ones, sharpens speech and pushes down background noise.

For someone who’s only a little hard of hearing, in a room that’s only a little too loud, that’s often enough. For more than that, it isn’t, and you should hear that from the person selling the app.

One thing I’d rather say plainly than leave to a footer: if conversation is hard across most of your day rather than in particular rooms, or if hearing dropped suddenly in one ear, that’s a doctor, and the second one is urgent. An app is a reasonable thing to try in the meantime. It isn’t a reason to put off the appointment.

The honest order to try them in

I build one of these apps, and this is still the order I’d give a friend.

Hearing aids first, if you can get to an audiologist and afford them. They’re tuned to you, and nothing on a phone is. Over-the-counter hearing aids are now an option for mild to moderate loss, usually at a lower price than a fitted pair, and that’s worth a look before any of the options above.

AirPods Pro second, if you’re an adult with mild to moderate loss and $249 is possible. One purchase, no subscription, and a feature the FDA has actually authorized. If they’d suit you, spend the money there and skip the apps entirely.

An amplifier app third. It earns its place in exactly two situations: the AirPods Pro gates rule you out, or you already own headphones you like and don’t want to buy new ones to hear dinner. Then the app is the only route that works with what’s in your pocket, and a free tier costs nothing to find out.

Money is the honest objection here, and it deserves a straight answer. Don’t pay a subscription for something a pair of earbuds you might already own would do better. Do pay for one if the earbuds are a $249 purchase you can’t justify for a problem you have twice a week.

Where Clarive fits

Clarive is the app I build, and it’s the third row of that table. Sound amplification through whatever headphones you already own.

The iPhone’s microphone picks up the room, and your headphones play it back with five presets to choose from: Clear, Conversation, Noisy Place, TV & Media, and Speech Clarity. Voice Isolation narrows the sound to whoever’s in front of you, and there’s a Live EQ if you’d rather shape it yourself. Everything runs on the phone. No account, no audio sent anywhere, and amplification works with no signal at all.

It also shows live captions in 40+ languages at the same time, which none of the other options on this page do, and it saves the transcript.

Three places it won’t suit you, and they’re the same three the table shows:

• It needs iOS 26 or later. Older iPhones can’t run it. That’s the flip side of the “does this need a new phone” question people ask on the forums, and for this app the answer is yes.
• It isn’t a hearing aid and it has no hearing test. It won’t measure you or tune itself to you. If you clear the AirPods Pro gates, Apple’s Hearing Test and the feature it feeds do something this can’t.
• It drives headphones, not hearing aids, and it can’t reach phone calls. It works on what the microphone hears in the room. If you already wear hearing aids, this page’s first half is for you, not this section.

The free tier gives you five uses a day. Past that it’s a subscription, from $4.99 to $29.99 depending on the billing period, with a lifetime option in there. Check the App Store for today’s price.

The short version

Two meanings, one question: do you already wear hearing aids? If yes, install your brand’s app, pair them under Settings > Accessibility > Hearing Devices if they’re MFi, and try Live Listen as a free remote microphone. If no, the order is hearing aids, then AirPods Pro if they fit your situation, then an amplifier app if they don’t.

Clarive is the one to try for that last case, with any headphones you own, and the free tier is enough to find out whether louder is what you needed.
