  1. 1.1

    · macOS 14.0+

    In-app update notifications land. Chromatic Tuner now checks for new versions on its own and tells you when one's available — no more wondering whether you're on the latest build.

    • New Check for Updates… command in the app menu.
    • Software-update section in Settings: shows the current version + build, a check now button, and an automatic-checks toggle.
    • Background check runs once a day; when something new is available you're prompted with a Download button that opens the release in your browser.
    • Every update is EdDSA-signed so the binary you download is provably the one we shipped.

    Updating: click Download in the dialog, mount the new DMG, and drag Chromatic Tuner into /Applications, replacing the old version. From this release on, future updates surface automatically.

  2. 1.0

    · macOS 14.0+

    The first public release of Chromatic Tuner for macOS. Built from scratch for guitarists, bassists, bowed-string and folk-instrument players — and for anyone who wants a real tuner that lives on Core Audio instead of in a browser tab.

    • YIN pitch detection — ±0.14 ¢ on pure tones, ±1 ¢ real-world. A0 to C8 (27.5 Hz – 4186 Hz). Octave-error correction for plucked strings. ~22 Hz update rate.
    • Two display modes — 31-LED bar with hardware-accurate ticks and a Knight-Rider intro sweep, or a Peterson-style rotating strobe with a hard ±0.5 ¢ deadband.
    • 15 instrument presets — guitar (Standard, Drop D, DADGAD, Open G, half-step down, 7-string), bass (4 + 5-string), violin, viola, cello, double bass, ukulele, mandolin, 5-string banjo, and pure chromatic.
    • Eight historical temperaments — Equal, Just, Pythagorean, ¼-comma Meantone, Werckmeister III, Kirnberger III, Vallotti, Young II — with movable tonic for non-equal systems.
    • Calibration + transpose — A4 reference 349.0–499.9 Hz (with 415 / 440 / 442 presets), capo through fret 11, ±11-semitone transpose for B♭ trumpet, A clarinet, capo'd guitars.
    • Reference tones — tap any string row to play a clean sine reference; keyboard shortcuts c d e f g a b.
    • Lives in your menu bar — 360 px popover, one click from the macOS menu bar. Or float the main window with always-on-top for stage use.
    • Universal binary — runs natively on Apple Silicon and Intel Macs (macOS 14 Sonoma or later).
    • Fully offline — zero outbound network calls, no telemetry, no account, no analytics. Audio is processed in memory and discarded.
