See scales in interval colors on guitar, bass & ukulele. 17 scales in all 12 keys, one-tap relative-key pivots, and a guided tour. Fully offline, no ads, free. See the fretboard in interval colors. Fretika is a visual learning tool for guitar scales and chord tones — look, touch, and let the patterns sink in. ◆ Guitar, bass & ukulele Switch between 6-string guitar, 4-string bass, and ukulele (high-G). Every scale map and the reinterpretation engine works on all three instruments. ◆ 17 scales & chord tones Pentatonics, blues, major, three minors (natural, harmonic, melodic), five modes, and five 7th-chord arpeggios — in all 12 keys. ◆ Interval colors Root, 3rd, 5th… every function has its own color, and the same function keeps the same color in every scale. Learn the system, not just the shapes. ◆ Compare, then re-frame Compare scales over the same root and see the difference in color. Flip on Relative and the notes stay put while the root and meaning change — modes finally make sense, right on the fretboard. ◆ Two views A realistic fretboard with note names, and an endless interval grid for seeing pure patterns. ◆ Pentatonic boxes. Fully offline. No account. No ads. Your pocket fretboard cheat sheet. ◆ An easy start A welcome intro and an interactive guided tour walk you through the core controls on the live interface — revisit anytime from the gear menu.
