Tune up, look up a chord and practice to a click, all one click from your toolbar. TUNER: play a string, it finds it • Auto-detects which string you're playing, so there's nothing to select • A big needle plus a live pitch line shows exactly how far off you are and which way to turn • A green check locks in for each string once it's in tune, and you'll see when all six are done • Tap any string to hear its note and tune by ear • Guitar, bass (4- and 5-string) and ukulele, with 15 tunings including Drop D, half step down, Open G, Open D, DADGAD, Drop C and low-G uke • A4 calibration from 430 to 446 Hz • Clear messages for "listening", "too quiet", "too low / tighten" and "in tune" CHORDS: charts you can play • Tap the chart to strum it, or hear it note by note • Up to 4 shapes per chord, from open position up the neck, with the starting fret marked • 15 chord types in all 12 keys: major, minor, 7, m7, maj7, sus2, sus4, add9, 6, 9, m6, 7sus4, dim, aug, m7♭5 • Type any chord name (F#m7, Bbmaj7, Dsus4…) to jump straight to it • "Chords that go with this one": tap the six chords in the key to hear a progression • Left-handed charts and note names on the dots METRONOME: practice that pushes you • 30–260 BPM with a slider, +/- buttons, arrow keys and tap tempo • Swinging pendulum and beat lights • Tap any beat to make it accented, normal or silent • Eighth notes, triplets and sixteenths • Speed trainer that raises the tempo every few bars until you hit your goal EASY TO USE • One big button per tool, with large tap targets • Remembers your last tool and settings • Keyboard: Space to start or strum, 1 2 3 to switch tools, arrows for shapes or tempo, T for tap tempo, Alt+Shift+G to open • Follows your system's light or dark mode No account, no ads, no tracking.
