The most visual, interactive guitar theory companion. Scales, chords, CAGED, real progressions, alternate tunings, and built-in practice drills — all connected, all in one place.
Major, minor, all 7 modes, pentatonic, blues, whole tone, and diminished. Every scale shows its formula, degrees, and up to 5 position boxes.
From basic triads to altered dominants and 13th jazz chords. Every chord shows curated, physically playable fingering diagrams across open, mid, and high neck positions.
A full guide to all 5 shapes with interactive fretboard overlays. See exactly where each shape sits for your key and how they connect across the neck.
Named progressions across Pop, Rock, Blues, Jazz, and more — plus a custom builder that lets you stack any chord from any key. Hit Play and hear real guitar audio as the fretboard updates live.
Lock to any of 5 scale position boxes and the fretboard dims everything outside your box. Practice one position at a time without getting lost.
Hear every chord played back with real sampled guitar notes. Tap any chord in the library or let the progression player cycle through at your BPM.
Six new features that make Fretionary work the way real guitarists practice — across tunings, with smart suggestions, and built-in tools to keep you sharp.
Drop D, Drop C, DADGAD, Open D / G / E, Eb & D Standard. The fretboard recalculates every note for the active tuning. Standard and Drop D are free.
Every chord shows where it commonly resolves to with the voice-leading reason — V7 → I, sus4 → major, ii° → V. Tap a card to jump straight there.
Three modes — Name the Note, Find the Note, String Drill — across three difficulty levels. Build real fretboard memory with quick-fire rounds.
BPM 40–240, six time signatures including 6/8 and 7/8, accent + offbeat clicks, tap-tempo, and a drift-corrected timer that stays steady even at 200+ BPM.
Heart any chord, scale, or progression to save it for later. Recents auto-track the last 20 you've explored. One ♥ Saved sheet, available on every tab.
An in-app feature catalog with Free / Pro markers on every item, plus quick-jump links to each section. Discover everything Fretionary can do in one screen.
Voicings sourced from real guitar pedagogy — open chords, barre chords, and jazz shapes across the full neck. Not algorithmically generated. Actually playable.
The CAGED system links 5 repeating shapes that cover the whole neck. Once you know all 5, you can play any chord or scale anywhere — in any key, at any fret.
22 progressions across every genre — plus a custom builder that lets you stack any chord from any key. Hit Play and hear real guitar audio while the fretboard shows you every chord shape in sequence.
