In their own words
ChromTuner
ChromTuner combines a native macOS chromatic tuner with a free browser tuner and a separate iPhone app. On Mac, YIN pitch detection covers A0 to C8 and is reported at ±1 cent accuracy in real-world use. The app offers an LED meter, Peterson-style strobe, vintage needle, and drifting sine-wave display, plus 15 instrument presets, eight historical temperaments, adjustable capo, custom A4 reference, and transposition up to ±11 semitones. A separate-window metronome covers 40–240 BPM, tap tempo, and meters from 2/4 to 7/8. Audio can come from the built-in microphone or macOS-recognized USB interfaces and Aggregate Devices through Core Audio. The maker says the Mac app processes microphone audio in memory without recording, transmitting, or making outbound network connections. The Mac app costs $6.99, paid once and requires macOS 14 Sonoma or later; iPhone Pro is $6.99, paid once. The browser and basic iPhone tuners are free. Full-band rehearsals and noisy stages may make room-microphone tuning unreliable; the maker recommends a wired pickup or DI input.
