TonePoet: Guitar Tuner

Get in tune and get back to playing. TonePoet brings clear guitar tuning, chord and scale reference, and a metronome into one focused practice companion. HEAR IT. SEE IT. TUNE IT. See the note and whether your string is sharp or flat, with cent and frequency feedback when you want more detail. A readable dark interface keeps the tuning target in view. FIND YOUR NEXT SHAPE Look up chords and scales with fretboard views. Explore note, key and chord context in Prediction mode, then keep time with the metronome. TRY A DIFFERENT TUNING Move between Standard, Drop D, Open G, half-step down and DADGAD targets without keeping another chart beside you. MEASUREMENT WITH A HUMAN PURPOSE TonePoet uses established pitch-detection and signal-processing methods to turn microphone input into musical feedback. Results depend on the instrument, performance and surrounding sound. Made by photographers, backed by science: a shared creative philosophy from the maker of this app. The Pacific Northwest photography in the listing is the developer's own work; TonePoet is built for music. Microphone audio is analyzed on your device. No microphone recordings are saved or uploaded.
