Why Freequency
Tinnitus loosens its grip when you make room for it instead of fighting it. Each session, Professor Tone plays the sound you know all too well — and calmly listening for it gently trains your brain to let it fade into the background.
No miracle cure, no empty promises: the ringing may never fully disappear, but the disturbance can. Freequency wraps exposure techniques — recommended in the European tinnitus guidelines — in a game gentle enough to play every single day.
How it works
Step 1 · Find your match
Build your tinnitus tone with the tone generator: choose from eleven waveforms and noise shapes, dial in the exact frequency, and balance it between your ears. The closer the match, the better it works.
Step 2 · Turn toward the sound
In Catch the Tone, birds land around you in your own room — each one singing your tinnitus tone through spatial audio. Look, listen, and set them free. Session by session, you teach your brain that this sound is safe to let go.
Step 3 · Make it a habit
Practice daily, keep your streak alive, and log how you feel with the flower check-in. Over 100 days of guidance from Professor Tone, you'll watch your own discomfort curve bend.
In the app
Two daily exercises, a personal program, and everything around them designed to keep you gently on track.
Locate the birds carrying your tinnitus tone, and catch them one by one.
Sit back and let your tinnitus tone wash over you, gently drifting from ear to ear.
Place your tinnitus tone in the environment around you and practice with it — not with a generic beep.
Watch personal videos and animations from audiologists and psychologists, unlocked as you practice.
See how your tinnitus relates to your sleep, habits, and daily activities — week by week.
After each session, log how you feel with the flower check-in and look back on how far you've come.
Professor Tone helps you keep your rhythm. Miss a day? A streak freeze automatically saves your streak.
Estimate the softest tones you can hear, per ear — an indication, not a diagnosis, to discuss with your audiologist.
Your streak on your wrist, the professor on your home screen, and a Live Activity during every session.
Your personal data does not leave your device and is never shared with third parties.
The 100-day program
Professor Tone guides you through a structured program built on exposure therapy and Acceptance and Commitment Therapy. Along the way, the scientifically validated Tinnitus Functional Index measures how you're really doing — four times.
Understand what tinnitus is, match your tone, and learn what to do on the hard days.
Discover how your brain can learn to filter the sound — and start training it.
A calmer body makes the sound less demanding. The focus shifts to feeling safe again.
With ACT techniques, you change your relationship with the sound — not the sound itself.
Everything comes together in your own plan for the days after day 100.
The science
Exposure therapy is recommended in the European guideline for tinnitus treatment — and Freequency is built precisely on that principle. Combined with Acceptance and Commitment Therapy, the program teaches your brain, step by step, that your tone no longer deserves an alarm response.
In the program you'll learn directly from leading names in the field — including Steven C. Hayes, founder of ACT, audiologist Richard S. Tyler of the University of Iowa, audiologist Tricia Scaglione, clinical physicist-audiologist Jan de Laat of the LUMC, and psychologist and ACT specialist Gijs Jansen.
Leading audiologists, clinical psychologists, and scientists contribute to the scientific foundation of Freequency — not as a formality, but as active partners in its ongoing development.
Reviews
Honest experiences from people who practice every day.
My tinnitus tone is still there, but the disturbance is gone.
Maybe it works, maybe it doesn't, but I've been symptom-free for a month!
Well, what do you know — that whistling is gone.
You teach your brain that the sound is simply there. That it's not dangerous.
Ten minutes of rest on the couch. That became my moment.
This is how I got my grip back.
From being tinnitus, back to being Ingrid.
Finally sleeping without the radio on. First time in months.
The professor feels like a friendly coach in your pocket.
Finally I understand what's happening in my head. That alone brings calm.
After a few weeks I noticed I was just reading a book again in the evening.
The ringing is still there, but it no longer decides my day.
My 200-day streak says enough, I think.
Small effort, ten minutes a day. And it really works.
For professionals
Hospitals, audiology centers, hearing care professionals, and CBT or ACT practitioners use Freequency as a structured home exercise for their tinnitus patients. Clients actively engage with their tinnitus in a safe, familiar environment — making the most of the time between appointments.
The practitioner dashboard shows the metrics that matter — tinnitus intensity, daily playtime, and session duration — so you can see who is progressing independently and who needs an extra appointment. Freequency is not a medical device and does not replace professional care.

Freequency is available in both the App Store (iPhone) and Google Play (Android). Search for 'Freequency' or use the download links on our website at freequency.app.
On iPhone, Freequency works on devices running iOS 18 or higher — including the iPhone XS, XR, 11, SE (2nd generation), 12, 13, SE (3rd generation), 14, and 15. You can check if your device supports iOS 17 in your phone's settings. On Android, your device needs to support ARCore. You can check the full list of compatible Android devices at developers.google.com/ar/devices.
The app is not free, but you can try the tone matching tool at no cost to see if your tinnitus sound is available in the app. If you're happy with the match, you can choose a monthly or yearly subscription. Newsletter subscribers may also receive special discount offers.
When you first open the app, you'll be guided through the tone setup automatically. You can also access it later via My Profile → Manage Tones → Create New Tone. The tone maker lets you create and fine-tune a computer-generated tinnitus sound to match what you hear in your head. Always use earphones or a Bluetooth headset — not your phone's speaker — for the most accurate result. Step-by-step guides are available on our website for both iPhone and Android.
It's a screening test in the Practice tab that estimates your hearing threshold for each ear across six frequencies and stores the result as an audiogram in your profile. It's currently only available in the Netherlands, so the option is hidden on devices set to another region. It's a screening, not a diagnosis — take the result to an audiologist or your GP.
Yes. Freequency is grounded in scientific research demonstrating a positive effect on tinnitus loudness through the use of Virtual Reality. The approach is based on exposure therapy and the principles of neuroplasticity — training the brain through repeated exposure to reduce the emotional response to tinnitus. You can read more about the research on our website at https://freequency.app/articles/clinical-research.
Results vary from person to person. We generally suggest allowing 6–8 weeks (roughly 100 days) of daily sessions before drawing conclusions, based on studies showing that neuroplasticity takes approximately that long to develop through repeated training. Some users notice positive changes sooner, while for others it may take a bit longer. 29% of daily users report improvement after four weeks.
We recommend one 10-minute session per day for 100 days. Playing more than once a day won't speed up your progress — your brain also needs time to rest and process between sessions.
There's no single best time that works for everyone. Playing in the morning can be a mindful way to start your day. In the evening works well too, especially if you can rest afterward. What matters most is choosing a moment when you can truly tune in to how the session feels.
Take a few minutes to unwind in whatever way suits you — a short walk, journaling, or simply sitting quietly. Avoid immediate stimulation like TV, scrolling through your phone, or busy activities. Giving your brain space to process after a session helps get the most out of the experience.
Two. Catch the Tone is the interactive 10-minute session where you locate the birdscarrying your tone and catch them one by one. Soundscape is a calmer 15-minute session where you sit back and let your tone drift from ear to ear. Both count towards your streak and your 100 days.
Yes — every completed session counts towards your streak and your 100 days. Catch the Tone is still the heart of the programme, so keep it as your default and use Soundscape on days when you'd rather not be up and moving.
No. Session length is now fixed: 10 minutes for Catch the Tone and 15 for Soundscape. Theshortened and extended options are gone, because a consistent session length keeps your results comparable from day to day and matches what the programme asks of you: one ten-minute session a day, for a hundred days.
It can be. With exposure therapy — the principle behind Freequency — it's not uncommon for the tinnitus experience to feel more intense at first. This is your emotional brain reacting to having its 'alarm signal' triggered. With repeated exposure, the goal is to reduce that aversive response over time, ultimately leading to improvement in both intensity and perceived burden. Most users experience a turning point between 2 and 4 weeks, though this varies. If you need a break, take one — even a few days off can help you return with a fresh perspective. Always listen to your body and give yourself the time you need.
Not necessarily. If the tone matches your tinnitus perfectly, it may blend in and become hard to distinguish — which is actually a good sign. Sound localization is just one element of the experience; the visual environment also plays a major role in signaling to your brain that the tinnitus is safe rather than threatening. If you suspect noise cancellation is interfering, check your phone's settings under Accessibility → Audio & Visual and toggle Noise Cancellation on or off.
We've built an extensive sound library covering a wide range of frequencies, but we understand that some people experience sounds that fall outside of it. The closer the match, the more effective the experience — but even an approximate match can still be beneficial. Sound localization is just one part of the process; the immersive visual environment also contributes significantly to retraining your brain's response. If needed, you can try a subtle character adjustment so the tone is slightly different from your tinnitus. More information about tone setup is available at https://freequency.app/help/tones
Yes. In the tone manager, you can check multiple tones to combine them during your session. All checked tones will play together in the game. Find your tones under My Profile → Manage Tones.
Your streak tracks how many consecutive days you've played. You'll find it in My Profile, shown as a flame icon. After each session, you're asked to rate how loud your tinnitus was that day using a slider — a colored flower is then assigned based on your rating. These flowers appear in your streak overview, giving you a visual history of whether your tinnitus loudness has decreased, stayed the same, or increased over time.
Go to My Profile → Change Preferences. Here you can set the time you'd like to be reminded to play, and turn streak reminders on or off.
This option is currently available for iPhone users only. In the Freequency preferences, you can toggle the 'Whistle when the bird is found' setting under the 'Practice' section.
Don't panic. After an update or app restart, the app may need a moment to sync. Close the app completely, wait a few minutes, then reopen it. Your data is most likely still there and will reappear once the sync completes.
Any data collected helps us understand whether Freequency works better or less well for specific types of tinnitus. All data is processed anonymously — your name or identity is never included in any conclusions or reports.
