Hzera - Tinnitus Relief

Your tinnitus has a frequency. Find it in minutes, then retrain your brain with sound therapy tuned exactly to it, day and night. $4.99 once. No subscription, ever.

Tinnitus is unique to you. Your sound tools should be personal too.

Hzera pairs an on-device tinnitus assessment with two customizable listening modes. Find your pitch, then apply real-time notch filtering or a four-tone Coordinated Reset sound pattern.

THE TINNITUS ASSESSMENT (FREE)

A guided, on-device assessment characterizes your tinnitus in about 12 minutes:

• Guided pitch matching, octave check, and reliability retest.
• Noise-like tinnitus (hissing, roaring) matched with band-limited noise.
• Hearing screen and loudness in sensation level.
• Masking and residual-inhibition responses for personal comparison.
• Hyperacusis and red-flag screening, plus a 10-question impact score.

Apply your result directly to therapy, or use the 3-minute quick assessment.

TWO THERAPY MODES

Notch Sound Therapy removes a narrow band at your calibrated pitch. Research has explored lateral inhibition as a possible mechanism, but clinical findings are mixed.

Coordinated Reset (CR) plays four tuned tones around your frequency in varied sequences, based on an experimental neural-desynchronization concept.

ADVANCED NOTCH CONTROL

• Guided Standard, Broad Range, Related Tones, and Music setups
• Notch width from ½ to 4 octaves, with Deep and Soft depth options
• Enhanced edge bands and optional related-frequency notches
• Guardrails prevent incompatible filters from stripping most audible sound
• Per-ear notch with independent left and right frequencies
• Safe-capped automatic loudness compensation

Settings apply live. The spectrum labels active notches and boundaries and supports full-screen zoom.

PRECISION CALIBRATION, YOUR WAY

Use a slider with 5 Hz fine-tuning or a sweep you lock at your matching pitch.

24 SOUNDSCAPES + CUSTOM IMPORT

Noise, nature, ambient textures, and music beds, notched in real time. Frequency Fit measures source energy around your notch to help you choose. Premium users can import DRM-free audio from Files or Music.

YOUR VOLUME, YOUR WAY

Set therapy loudness independently of system volume. Mix With Other Audio can let other apps play alongside Hzera.

SLEEP MODE (PREMIUM)

Start with a notch soundscape, then cross into Coordinated Reset after 30 to 90 minutes.
