ReSound Smart 3D

Review by eFreeware

Hearing aids used to be adjusted at the clinic and then left alone until the next appointment. If a restaurant turned out to be louder than expected, or a lecture hall muffled speech, the only option was to live with it and mention it weeks later. Modern aids can do far more than that, but only if you have a way to reach those settings without booking time with your hearing care professional.

For ReSound hearing aids, this app serves as that layer. It comes from GN Resound, the company behind the aids themselves, and it has been on Google Play since April 2017. The app is free, carries no ads and offers no in-app purchases, which fits its role: it is a remote control and support tool for hardware you already own, not a product trying to sell you something else.

What makes it interesting is the range of jobs it covers. Volume and program changes are the basics, but the app also handles tone shaping, saved listening profiles, battery checks, a way to find misplaced aids, tinnitus sound settings and a channel for your clinician to send updated settings. For a free download, that is a lot of ground.

Everyday control of programs and sound

The core of the app is direct control. You can change the volume on your hearing aids, mute them, and switch between manual programs and streamer programs. Each program can be renamed, so instead of remembering what a numbered setting was meant for, you can label it in a way that makes sense to you. That small piece of housekeeping makes a real difference when you are cycling through options in a hurry.

Beyond volume, the app offers treble, middle and bass adjustments. A Favorite can hold your preferred settings, and you can tie it to a place. The idea is that a configuration you like for one place can be recalled when you are there again, rather than rebuilt from scratch each visit.

Sound Enhancer goes further, with speech focus plus noise and wind-noise levels. The developer notes that availability depends on your hearing aid model and how your hearing care professional fitted it, and the same caveat applies to other advanced features. So the app's ceiling is partly set by the hardware on your ears and the way it was configured, not by the app alone.

If you use ReSound streaming accessories, the app can adjust their volume as well. That is a useful consolidation: one place for the aids and the accessories paired with them, rather than separate controls for each piece.

Favorites, battery checks and finding lost aids

Two features stand out for very different reasons. The first is the locator, which helps you find hearing aids that have been lost or misplaced. Anyone who has patted down a couch, a coat pocket and a nightstand in the same anxious ten minutes will understand why this matters. Hearing aids are small, expensive and easy to set down absent-mindedly, and having the app as a first place to check is a genuinely practical addition.

The second is battery monitoring for rechargeable hearing aids. Knowing the charge level before you head out for a long day is the sort of information that prevents an awkward silence in the middle of a conversation. It is a simple function, but it belongs in the same app as everything else rather than in a separate utility.

The Favorites system ties these threads together. Because a Favorite can be tagged to a location, the app nudges you toward building a small library of listening setups for the places you return to. That is a more thoughtful design than a plain volume slider, and it rewards a little initial effort.

Tinnitus sounds and remote help from your clinician

For wearers who use a Tinnitus Sound Generator, the app includes a tinnitus manager where you can adjust sound variation and frequency, and select Nature Sounds. Here too, the model and your clinician's fitting decide what is available. Where it is supported, having these controls on a phone means you can tune the sound to the moment rather than settling for whatever was configured at the last visit.

ReSound Assist is the other half of the picture, and it is the feature that most changes how the app fits into daily life. Remote support lets a hearing care professional adjust your settings, and software updates arrive the same way. According to the developer, updates to programs and hearing aid software no longer require a clinic visit.

That matters most for people who find appointments inconvenient, whether because of distance, scheduling or mobility. It does not remove the clinician from the process; it changes the channel. Adjustments still come from a professional, but they can arrive without a journey. For anyone who has put off a tweak because the next opening was weeks away, this is the strongest argument for keeping the app installed.

What you need before the app does anything

This is a companion app, so the first requirement is ReSound hearing aids. Without them, there is nothing to control. The app is free to download, but the useful work happens between the phone and the aids, and the aids are the part you acquire separately.

The second requirement is compatibility. The developer directs users to the ReSound app website for current information about which mobile devices work with the app. That is worth checking before you count on it, because phone compatibility in this category is not universal and can change over time.

Third, the developer recommends running the latest software version on the hearing aids and suggests contacting a hearing care professional if you are unsure. Product and feature availability also varies by market, and the developer advises contacting your local ReSound representative on that point. In other words, the app's feature list is a menu of possibilities, and what you actually get depends on your model, your fitting, your phone and where you live.

The app is also meant to teach you its features and how to use them, which makes sense given the number of settings involved. The most recent update, from March 2026, is described as general performance and stability improvements, so the app is still being maintained rather than left as-is.

Who gets the most from it

The clearest fit is someone who already wears ReSound hearing aids and wants more direct control over how they sound in different places. If you find yourself wishing you could nudge the tone or switch programs without waiting for an appointment, this is the tool built for that. The Favorites and location tagging reward people who are willing to spend a little time setting things up once and reusing them.

It also suits wearers whose circumstances make clinic visits a chore. ReSound Assist turns a settings change into a remote request, which is a meaningful convenience for anyone far from their provider or juggling a tight schedule. And for those using a Tinnitus Sound Generator, the tinnitus manager adds a level of day-to-day adjustability that is otherwise hard to come by.

The app's usefulness scales with the hardware. A wearer with a model that supports Sound Enhancer and the tinnitus features will find far more here than someone with a more basic fitting, and the developer is upfront that availability depends on the model and the clinician's setup. It is also, by design, tied to one brand of hearing aids; it is a control surface for ReSound devices, not a general hearing tool.

With over a million installs and a 4.5 average from more than 48,000 ratings, plenty of people have taken it up. That is a broad base for a medical companion app, and while ratings never tell the whole story, the volume of them suggests it has become a standard part of the ReSound experience.

A companion worth installing for ReSound wearers

ReSound Smart 3D does the job you would want from a hearing aid app and then adds a few things you might not expect: a locator for misplaced aids, battery monitoring, a tinnitus manager and a remote line to your clinician. It is free, it carries no ads and it asks nothing of you beyond the aids it was built for.

If you wear ReSound hearing aids and your model supports the advanced features, installing it is an easy call. The Favorites system and remote adjustments are the parts I would expect to matter most over time, because they reduce the friction of getting your aids to sound right in the places you actually spend time. If your aids are a more basic model, the app still offers volume, program and tone control, but the ceiling is lower.

For anyone weighing it up, the deciding factor is not the app itself but the pairing: the right aids, a compatible phone and a fitting that opens up the fuller feature set. Where those line up, this is a well-rounded companion that deserves a spot on the home screen rather than sitting forgotten in a folder.
