## What is Hzera?

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.

DESIGNED FOR DAILY USE

Therapy, Tune, and Progress tabs keep playback close at hand. Includes a daily goal, live timer, profiles, and headphone-disconnect auto-stop.

### 3/5 — Brown noise cut out

*2026-07-26*

The app seems good so far - just started today. The issue is the brown noise file for the notched therapy cuts out briefly several times. That makes it not a sleep noise option.

**Developer response:** Thank you for taking the time to report this. You were absolutely right: Brown Noise should remain uninterrupted, especially when used for sleep. We traced the issue to the audio loop and fixed it in version 2.4. We also reviewed all 24 built-in soundscapes, including Pink and White Noise, Heavy Rain, and Forest, to ensure smooth, continuous playback during long and background sessions. We appreciate you helping us improve Hzera so early in your experience. If you ever notice anything else, please contact us at support@hzera.com - we’re always happy to help!

## Frequently asked questions about Hzera

### How does Hzera work to relieve tinnitus?

Hzera uses two primary methods: Notch Sound Therapy, which removes your tinnitus frequency from audio to reduce neural activity, and Coordinated Reset (CR) Neuromodulation, which disrupts synchronized neural firing patterns. Both are based on peer-reviewed neuroscience research.

### How do I calibrate Hzera to my tinnitus?

Hzera offers two calibration methods: a slider for fine-tuning in 5 Hz increments, or a sweep calibration where you tap pause when you hear your tinnitus pitch. Volume matching then calibrates the therapy to your perception level, taking just a few minutes.

### Can I use my own audio with Hzera?

Yes, premium users can import their own DRM-free audio files (MP3, M4A, WAV, AAC, AIFF, CAF) to use as therapy soundscapes. The app automatically normalizes volume and applies notch filtering.

### Does Hzera have ads?

No, Hzera is ad-free. The app is designed for a focused, distraction-free experience, and all data stays on your device.

### What devices does Hzera support?

Hzera is available for iPhone and iPad devices. It works entirely offline after installation.

### What is the age rating for Hzera?

Hzera has an age rating of 12+. This is suitable for a wide range of users seeking tinnitus relief.

### How often is Hzera updated?

The latest version of Hzera is 1.7, last updated on April 16, 2026. Updates typically include improvements to therapy algorithms and user experience.

### Is Hzera free to use?

Hzera offers free features including full frequency calibration. Additional features and customization options are available through in-app purchases for premium users.

## Version history (last 5 releases)

### 2.5 — 2026-08-20

V2.5 is a minor fix that removed the loop point from Brown, Pink, and White Noise. These stationary soundscapes now generate continuously for smooth, long background listening without restarting the track, improving the sleep experience with Hzera.

### 2.4 — 2026-08-09

Thank you for taking the time to send your feedback to our team. V2.4 makes advanced notch controls easier to understand, soundscape playback more dependable, and your on-device data easier to manage.

- Guided Setup offers four compatible starting points: Standard, Broad Range, Related Tones, and Music.
- Enhanced Notch adds visible edge bands immediately outside your calibrated notch, including independent left and right frequencies.
- Frequency Fit shows how much source sound is available around your notch, helping you compare soundscapes without predicting an outcome.
- Related Frequency Notches now include safer combination guardrails.
- Per-ear playback is more precisely aligned, and Ear Balance now works through the independent left and right paths.
- Changing soundscapes during therapy now takes effect immediately and stays selected after pause and resume.
- Fixed brief audible gaps when Brown Noise and other bundled soundscapes loop during notched therapy. All 24 built-in soundscapes now use continuous-loop transitions for long-form and background listening.
- Saved profiles, imported audio, listening sessions, and assessment history now have clear, separate delete controls with precise confirmation messages.
- VoiceOver now announces Delete as an action on saved profiles, imported audio, and individual sessions while double-tap selection continues to work normally.
- Deleted items stay deleted after relaunch, including files and records stored outside the visible list.
- All bundled soundscapes have also been remeasured and normalized for more consistent listening levels.
- Improved playback transitions, session timing, long-session memory use, live spectrum detail, and Mac window sizing.

### 2.3 — 2026-07-22

V2.3 makes advanced notch controls easier to understand and playback more dependable.

- Guided Setup offers four compatible starting points: Standard, Broad Range, Related Tones, and Music.
- Enhanced Notch adds visible edge bands immediately outside your calibrated notch, including independent left and right frequencies.
- Frequency Fit shows how much source sound is available around your notch, helping you compare soundscapes without predicting an outcome.
- Related Frequency Notches now include safer combination guardrails.
- Per-ear playback is more precisely aligned, and Ear Balance now works through the independent left and right paths.
- Changing soundscapes during therapy now takes effect immediately and stays selected after pause and resume.
- All bundled soundscapes have been remeasured and normalized for more consistent listening levels.
- Improved playback transitions, session timing, long-session memory use, live spectrum detail, and Mac window sizing.

### 2.2 — 2026-07-19

See exactly what Hzera is doing, with corrected notch depth and smoother audio.

- NEW: A fully labeled live spectrum. See 1/4x, 1/3x, and 1/2x below your frequency, the center notch, and 2x, 3x, and 4x above it, with every boundary drawn.
- NEW: Enlarge the spectrum, then pinch, drag, or use the zoom controls to inspect it.
- FIXED: Deep now completely removes sound exactly at the selected frequency. Soft is a clearly different 12 dB reduction with the same two-sided boundaries.
- FIXED: Related-frequency notches now extend below and above your calibrated frequency.
- IMPROVED: Starting or resuming therapy brings the spectrum into view on iPhone and iPad.
- IMPROVED: Audio-session work is serialized away from the interface thread for more responsive starts and interruption recovery.
- FIXED: Sleep Mode no longer leaves an extra tone in notch therapy, and its timer survives calls, Siri, and other interruptions.

### 2.1 — 2026-07-17

Keep your feedback and suggestions coming; they help make Hzera the best app for tinnitus relief for everyone. 

Sleep in notch, wake up having done CR. Plus a notch that no longer costs you loudness.

- NEW: Sleep Mode. Fall asleep to your notch soundscape, then Hzera crosses gently into Coordinated Reset after 30, 45, 60, or 90 minutes and keeps it running until you stop it (Premium).
- NEW: Automatic level compensation. A deep, wide, or harmonic notch removes real energy from the sound, which is used to make therapy quieter the more notch you use. Hzera now measures what the notch removes and automatically restores the level, capped at a safe +6 dB.
- NEW: A simpler main screen. Nineteen sections in one long scroll became three tabs: Therapy, Tune, and Progress. The playback bar stays visible on every tab, so stopping therapy never requires navigating.
- NEW: The Sleep Timer can now be set before therapy starts, and the Sleep card states the resulting plan for your session, including when a timer would end therapy before the CR hand-over.
- NEW: The tinnitus assessment now lives on the Progress tab as well as in Settings, with one-tap re-testing and your assessment history beside your session stats.
- FIXED: Sleep Timer taps could silently do nothing while the spectrum analyzer was running.
- FIXED: Starting a session in CR no longer shows an inert offer to "switch to CR"; the Sleep card now explains that the hand-over applies to notch sessions.
