Tinnitus Sound Therapy for iOS
Personalized Relief for a Sound You Can't Escape
Zentone delivers research-backed sound therapy tailored to your exact tinnitus frequency. From a guided evaluation that matches your pitch and loudness, to daily sessions, daily symptom logs, and long-term trend charts — everything is built around your specific experience of tinnitus.
A structured approach from evaluation to long-term relief.
Start by identifying your tinnitus type — ringing, buzzing, hissing, roaring, clicking, or other. For tonal tinnitus (ringing, buzzing), Zentone walks you through a guided frequency sweep or a manual pitch slider to pin down your exact frequency in Hz. Then you match the perceived loudness. For broadband types, you skip straight to the symptom questionnaire.
After the evaluation, Zentone calculates your tinnitus profile — frequency, loudness, severity score — and recommends the right therapy. Tonal tinnitus gets notched sound therapy targeted at your matched frequency. Broadband types get masking therapy with white, pink, or brown noise.
Choose from four session goals: Quick Relief (5 min), Daily Therapy (30 min), Focus (25 min), or Sleep Aid (45 min). Pick your sound type, set your duration, and press play. Zentone's built-in safety limiter keeps volume within safe therapeutic ranges — no sudden loud sounds, no guesswork.
After each session, log how your tinnitus feels: loudness (0–10), how bothersome it is, sleep quality, stress level, and any contributing factors. Daily entries build the data needed to spot trends.
The Progress dashboard shows your session count, total therapy time, average loudness, and a trend chart across the last 7 days, 30 days, or all time. Most people notice measurable improvement within 4–8 weeks of consistent use.
Built specifically for tinnitus — not a generic white noise app.
A step-by-step evaluation identifies your tinnitus type, matches your pitch via a guided sweep or manual slider, and calibrates perceived loudness. Your profile drives everything downstream.
Pink noise with your exact tinnitus frequency removed. Research suggests notched therapy may reduce neural hyperactivity at the tinnitus frequency over weeks of consistent use. Best for ringing and pure-tone tinnitus.
Pure Tone, White Noise, Pink Noise, Brown Noise, and Notched Noise — each with a clear purpose. Pure tone for habituation, pink and brown noise for masking and sleep, notched noise for long-term therapy.
Quick Relief for immediate masking, Habituation for low-level daily therapy, Focus for background sound while working, and Sleep Aid for falling asleep. Each goal auto-selects a recommended sound type and duration.
A hardware-level amplitude ceiling prevents the audio from ever reaching unsafe levels. Volume increases are throttled, fades are smooth, and an emergency stop is always one tap away. Your hearing is protected.
Rate loudness and bothersome-ness on a 0–10 scale, log sleep quality and stress level, and note any contributing factors — noise exposure, caffeine, illness. Each entry is timestamped and saved locally.
Visualize your loudness trend over 7 days, 30 days, or all time. The dashboard shows session count, total therapy time, average loudness, and whether you're improving, stable, or trending the wrong way.
A 10-question symptom questionnaire adapted from the Tinnitus Handicap Inventory scores your functional, emotional, and catastrophic impact. Results place you in a severity category from Slight to Severe, guiding your treatment intensity.
Week 1 focuses on gentle acclimation with shorter sessions. Weeks 2–4 introduce targeted notched therapy at your matched frequency. Maintenance sessions follow to preserve your progress.
All data — your frequency profile, session history, daily logs, and evaluation results — stays on your device. No accounts, no cloud sync, no tracking. Zentone works without an internet connection.
Not all tinnitus has a matchable frequency. Hissing, roaring, and clicking types get masking therapy with multiple noise colors. The app routes you to the right approach automatically based on your evaluation.
Every therapy session is recorded — type, sound, duration, completion status, and pre/post loudness ratings. Review your history in the Progress tab to see consistency patterns over time.
Honest answers about what Zentone is — and what it isn't.
Medical Disclaimer: Zentone is a sound therapy tool designed to support habituation and symptom management. It is not a medical device and does not treat, cure, or diagnose tinnitus. If your tinnitus is severe, sudden, or accompanied by hearing loss, consult an audiologist or ENT physician.
Notched therapy removes your specific tinnitus frequency from a background noise (typically pink noise), then plays that "notched" audio during your sessions. Research suggests this may reduce the neural hyperactivity associated with tonal tinnitus at that frequency over time. It's why Zentone works to find your exact Hz — the notch has to be precisely placed to be effective.
Broadband tinnitus types (hissing, roaring, clicking) don't have a single identifiable frequency, so notched therapy isn't appropriate. Zentone automatically routes you to masking therapy using white, pink, or brown noise. These sounds help your brain habituate to the tinnitus signal over time through a different mechanism.
Sound therapy is not a quick fix. Most research on notched noise therapy and habituation shows results after 4–8 weeks of consistent daily use. Zentone's progress tracking is designed to show you the gradual trend even when day-to-day variation makes progress feel invisible.
Zentone offers two methods: a guided sweep (recommended) where tones play in sequence and you tap when you hear a match to your tinnitus, and a manual slider where you adjust the frequency yourself while listening. The guided sweep is more accurate for most people. The result — your matched frequency in Hz — is stored in your profile and used to generate all notched content.
Yes, when volume is kept at a safe level. Zentone's built-in safety limiter enforces a hard amplitude ceiling — approximately -4.4 dB below maximum output — and throttles volume increases to prevent sudden loud sounds. The app also warns you after 55 minutes in a single session and prompts you to take a break. Start at the lowest comfortable volume and increase gradually.
Zentone includes a 10-question assessment adapted from the Tinnitus Handicap Inventory (THI), a validated clinical tool. It covers functional impact (concentration, sleep, work), emotional impact (frustration, anxiety, irritability), and perceived control. Your score places you in a severity category from Slight to Severe, which helps you understand your situation and calibrate your treatment effort.
No. Zentone is a self-managed sound therapy tool. If your tinnitus is new, sudden, one-sided, pulsatile (beats with your heartbeat), or accompanied by hearing loss or dizziness, see a physician before using any sound therapy app. Zentone is intended for people who have already been evaluated and are looking for ongoing relief tools.
Everything stays on your device. Your frequency profile, session history, daily logs, and evaluation results are stored locally using Core Data. Zentone makes no network requests during normal use — there are no accounts, no analytics, and no servers holding your health data.
Zentone is built for anyone living with tinnitus who wants a structured, science-informed approach to managing it.
