## What is Fretika?

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.
