ScaleSpin vs KnowYourNeck

Spin the wheel, discover a scale, and start practicing. ScaleSpin makes daily scale practice simple, engaging, and a little more fun by randomly selecting your next scale. This app is dedicated to my music teachers, Matthew and Ice, whose patience, encouragement, and constant emphasis on the importance of scales have inspired countless hours of practice and growth.

Most guitar apps show you one scale or arpeggio at a time. KnowYourNeck shows you how everything connects. WHAT MAKES IT DIFFERENT • Multi Arp — Overlay up to three arpeggios simultaneously. See the chord tones for an entire progression on the neck at once, so you can practice connecting lines and navigating changes instead of just memorizing isolated shapes. • Target Notes — Identify which notes are safe landing points between chord changes. Overlaying a scale against an arpeggio shows you exactly which degrees work as target notes when you land on a new chord — the key to sounding musical instead of mechanical. • Play Along with Visual Overlay — Practice with backing tracks while the fretboard changes with every chord in your progression. A preview shows the upcoming scale or arpeggio before the change hits, so you can prepare your line in advance. Available in Jazz, Blues, Rock, Funk, Bossa, and Drone styles. EVERYTHING ELSE YOU GET • Intervals — Visualize the distance between any two notes across all six strings. • Scales — Every common scale and mode mapped across the full neck with color-coded degrees. • Chords — Triads, Drop 2, Drop 3, and Shell voicings with every inversion drawn as a grip across the neck. • Lick Builder (Pro) — Tap out note sequences on the fretboard and save your lines. • Quiz Mode (Pro) — Test intervals, chord tones, and scale mastery with detailed accuracy and speed stats. • Pitch Detection — Play a note and the app identifies it on the neck in real time. • Zen Mode — Full-screen fretboard with no chrome, for focused practice.
