What's new in 1.2: • Tuner: each string keeps a tick once it is in tune, a selected string moves on to the next untuned one by itself, and the app tells you when all are in tune. • Chords: fingerings checked against published charango chord charts. • Learn: lessons show the chord diagrams they teach, also in chromatic mode. • Simulation: Palm mute and Mute sit at the foot of the neck, as icons. • Faster, steadier launch and listening.

New in 1.1: • Fingering: every chord grip, finger by finger, and a drill that has you form the shapes on a life-size neck. • A redesigned Strum trainer: patterns grouped by style with Andean rhythms first, each drawn as its bar, with a big count-in and a live accuracy score. New patterns: saya, rin chilote, cachimbo, the repique and the huayño with chasquido. • The songbook grows from 5 to 37 songs: huayños, carnavalitos, pasillos, zambas and more, chords for every bar. • Simulation: a Palm mute button for the chasquido, Mute that stills the strings, and a song's chords all on screen. Home gets a Simulation shortcut. • Courses reviewed end to end, with new lessons on arpeggios, inversions and scale patterns. • The practice drills now sound like a charango, and have their own Practice tab in Learn. • Tools grouped by what you're doing. • Tuner: strumming across the headstock photo now sounds every string, and recent tunings stay charango-only.
