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.

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.

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.

Our Hzera users are the best! Thank you for your honest and helpful feedback. In this release: your volume, your way, plus major fixes for audio interruptions. - NEW: Therapy Volume slider. Set therapy loudness independently of your system volume; no more turning the whole phone up (and every alert with it) just to hear your soundscape. - NEW: Notch Depth. Deep removes your frequency band completely, best for noise soundscapes. Soft reduces it instead, preserving the character and loudness of music and imported tracks (Premium). - NEW: Import from your Music library. Pick tracks synced from your computer right from the app, no exporting to Files first (Premium). Apple Music subscription tracks are DRM-protected and can't be imported; your own files work. - NEW: Mix With Other Audio. An optional mode that lets alerts from other apps, glucose monitors, timers, and navigation play alongside therapy instead of stopping it. Lock screen playback controls are unavailable while the screen is on. - FIXED: Audio could fail to start after an interruption (a call, Siri, another app's alert) until the app was force-quit. Interruptions now recover cleanly, including ones that happen while the app is in the background. - FIXED: If iOS resets its media services mid-session, the app now rebuilds its audio engine and keeps playing instead of going silent until a force quit. - FIXED (VoiceOver): Selecting a soundscape used to trigger its preview instead of selecting it. Double-tap now selects and confirms aloud; preview lives in the actions rotor. - The spectrum analyzer now reflects your chosen notch depth.

Thank you all for your direct and helpful feedback! This release adds features you requested, improves existing capabilities to be more helpful, and places greater focus on accessibility. What's New (Version 1.9) A complete tinnitus diagnostic that flows straight into your therapy. - NEW: The Tinnitus Diagnostic. A guided, on-device battery that characterizes your tinnitus in about 12 minutes: pitch matching, a hearing screen, loudness in sensation level, minimum masking level, residual inhibition, and sound-sensitivity screening. Your original 3-minute assessment is still there as a Quick option. - NEW: Forced-choice pitch matching. Instead of hunting with a slider, answer a few simple "which is closer?" comparisons. A binary search finds your frequency, an octave check catches the most common matching error, and a quick retest scores how reliable your match is. - NEW: Noise matching. If your tinnitus hisses or roars rather than rings, match it with band-limited noise, a center frequency and width, instead of a pure tone. - NEW: Hearing screen and sensation-level loudness. A short pure-tone threshold test shows where your hearing sits and expresses your tinnitus loudness relative to it. - NEW: Masking and residual inhibition tests. Find the level that just covers your tinnitus, then see whether a minute of masking leaves it briefly quieter, a strong signal for how well sound therapy will work for you. - NEW: Hyperacusis and medical red-flag screening, with a referral prompt for features worth discussing with a doctor. - NEW: Apply to My Therapy. One tap sends your matched pitch and notch width straight into your therapy calibration. - Accessibility: VoiceOver labels and adjustable controls throughout the calibration and diagnostic, Dynamic Type support with capped scaling, and Reduce Motion support that quiets animations. - All diagnostic tests run entirely on the device and are screening-grade; Hzera is not a medical device. What's New (Version 1.8) Cleaner sound and a more powerful notch. - FIXED: Audio distortion. Gain staging has been reworked and a peak limiter added to the output, so soundscapes play clean at every volume instead of clipping. - NEW: Notch Width. Widen the notch from the study-standard ½ octave up to 1, 2, or 4 octaves for maximum notch strength if your tinnitus spans a range of pitches (Premium). - NEW: Harmonic Notching. Notch 2×, 3×, and 4× your tinnitus frequency simultaneously, for tinnitus that spans a set of harmonically related frequencies (Premium). - Per-ear notch is now visible to everyone on the dashboard so it's easy to discover, independent left and right notch frequencies remain a Premium feature. - The spectrum analyzer now reflects your chosen notch width and shows every active harmonic notch. - Switching between Notch and CR therapy now swaps seamlessly mid-session instead of stopping playback. - Sleep timer now holds full therapy volume and fades out only over the final minute, instead of fading across the entire duration. Pausing therapy shows a heads-up that the timer was canceled. - Daily goal, weekly chart, and total time now use the same pause-excluded math, so the numbers always agree. - Sessions that cross midnight now protect your streak on both days. - Per-ear sessions record both left and right frequencies; CSV export includes a Right Frequency column. - Session Insights: delete individual sessions with the new trash button (the old swipe gesture never worked); CR sessions no longer appear in the Soundscape Usage chart. - Daily reminder now explains when notification permission is denied and links to system Settings.
