You get a chord name and spell its notes; every miss shows the rule. Smarter practice: missed shapes come back sooner, known ones less often. A stricter "Mastered": right and fast after 14 days away, in Name it and Find it. Name it now asks for the shape's notes, low to high. The Notes quiz tracks all 78 spots on the neck. Every answer shows your time and the goal. Save your progress to a file and restore it. Cleaner Home screen and clearer, shorter lessons. ### 1.1 — 2026-11-07 - New name: Guitar Lens: Chords & Triads. - Daily Fretboard: five shapes a day, the same for everyone. Share your score without spoilers. - Name it accepts every correct name for a shape. Get one right and try to find the second. - Notes quiz: pick exactly which notes you're asked, like Bb, Eb and Ab. Every round shows all 12 answers. - Lessons: notes light up on the scale as each one plays, and a bigger Tap to play button. - Clearer words: "root" for chords, "inversion" for root position, 1st and 2nd, and "open" triads (also called spread). Notes are now spelled to match the chord, like Db in Bb minor. - Movable shapes first: quizzes skip shapes with open strings, and very wide stretches are gone where an easier shape exists. Change either in Settings. - New Settings and What's New screens, and a "What do you want to see next?" vote. - Learn from an expert: a note about the guitar course I'm taking. ### 1.0 — 2026-11-06 No release notes. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
