KookYar Piano Tuner

KookYar Piano is a precise, easy-to-read tuner for acoustic pianos. Pick any of the 88 keys, play it, and the needle shows how many cents sharp or flat the note is. HOW IT WORKS 1. Tap a key on the on-screen keyboard, or turn on Auto key detection. 2. Play that key on your piano. 3. Adjust the string until the needle sits in the green zone. Tip: tune one string at a time and mute the other strings of that note. FEATURES • Full 88-key range: A0 (27.5 Hz) to C8, including the lowest bass notes that most tuners cannot track • Scrollable piano keyboard with one-tap jumps to every octave • Auto key detection: the tuner follows whichever key you play • Needle gauge with a ±100 cent scale and a clear green in-tune zone • Reference tone: hear the target note for the selected string • Live level meter, so you can see the microphone hears your instrument • Adjustable reference pitch (A4 = 410 to 450 Hz) and microphone sensitivity • Persian note names (Do, Re, Mi…) with sori and koron quarter-tones • English and Persian interface. Follows your phone's language, and you can switch it in Settings • Dark, clean design that is easy to read on stage and in dim rooms • No ads, no account, works offline PRIVACY The microphone is used only while the tuner screen is open, and sound is analysed on your device. Nothing is recorded, stored or sent anywhere. FROM THE KOOKYAR FAMILY Open the KookYar Metronome and RadifYar (the Persian radif with audio examples) straight from the bottom bar.
