Modulate

Sound therapy for tinnitus, done honestly.

Three evidence-informed listening therapies, a guided pitch matcher, and progress tracking you can hand to your audiologist, all in a warm, quiet app designed to be lived with for hours a day.

Coming soon to the App Store $9.99, once. No subscription. No account.

Modulate's therapy screen with a session timer, a warm amber play button ringed by a daily goal indicator, and CR Neuro, Notched, and Ripple therapy modes.

Three therapies

Built on published research, not promises.

Each mode implements an approach studied in peer-reviewed literature. Research on sound therapy is genuinely encouraging and genuinely unfinished, so we cite it rather than oversell it.

CR Neuromodulation

Four tones, precisely placed.

Plays four calculated tones around your tinnitus frequency in randomized cycles, designed to disrupt the synchronized neural firing associated with tinnitus.

Tass et al., Restorative Neurology and Neuroscience (2012) · Wegger et al., Frontiers in Neurology (2017)

Notched Sound

Noise with your frequency removed.

Comfortable background sound with a one-octave notch centered on your matched pitch. The cited studies used tailor-made notched music with people who have tonal tinnitus; their findings don't establish the same outcomes for this version.

Okamoto et al., PNAS (2010) · Stein et al., BMC Neurology (2016)

Spectral Ripple

Constantly decorrelated sound.

Broadband sound with a shifting texture across frequencies. It doesn't depend on an exact pitch match. The study below tested this approach with people who have chronic tinnitus.

How it works

Find your pitch. Listen daily. Watch the trend.

Match your tinnitus

A guided frequency sweep estimates your tinnitus pitch in a few minutes, including an octave double-check for the classic matching mistake. A hearing test in Apple Health (for example from AirPods Pro) can suggest where the sweep starts.

Make it a habit

Daily reminders, session streaks, a goal ring, and a lock-screen Live Activity keep multi-hour listening sessions on track. A guided volume step helps you find a "just barely audible" level.

See your own evidence

Daily loudness ratings, the standardized THI questionnaire, and usage charts show your trend over weeks, exportable as a PDF report for your audiologist.

What to expect

We'd rather be honest than convincing.

The research behind these approaches followed people over weeks to months, and results varied between individuals: some improved meaningfully, some modestly, some not at all. That research can't tell you whether Modulate will help you.

What Modulate promises is the honest version: carefully built sound approaches, tools that make daily consistency achievable, and measurements so you can see whether it's working for you.

One price

$9.99. Once.

No subscription, no free tier with the good parts locked away, no "premium" upsell. You buy it once; it's yours.
