iTuner Lite vs Guitar Tuner Light

iTuner is a simple, accurate tuner designed for iPhone and Apple Watch. Tune your instrument quickly with clear pitch detection and easy-to-read guidance. Play a note, see whether it is sharp or flat, then tighten or loosen the string until it is perfectly in tune. On Apple Watch, iTuner now offers a focused tuning experience with practical controls for real playing situations: A4 calibration, input sensitivity, in-tune tolerance, cents display, and haptic feedback. A quick guide and instrument reference page help you tune common strings and sustained tones faster. iTuner works with a wide range of instruments, including guitar, bass, violin, viola, cello, ukulele, mandolin, banjo, woodwinds, brass, piano, timpani, and any instrument that can sustain a tone. Audio is used only for real-time pitch detection. iTuner does not record, save, or upload your sound. Whether you are practicing at home, rehearsing with a band, or tuning before a performance, iTuner gives you a clean and reliable tuning experience right on your wrist or phone.
