redLUX Guitar: Scales & Chords

Stop memorizing shapes you don't understand. redLUX shows you why the notes sound the way they do, then helps you turn that into music. A studio-accurate tuner, a chord and scale library, an interactive fretboard trainer, a jam station and a songwriting studio in one app. Everything a guitarist needs, without juggling five subscriptions. SEE THE NOTES THAT MATTER Most scale apps show a wall of identical dots. redLUX builds on the pentatonic boxes you already know (circles), then adds triangles to mark the note that gives each scale its character. The #4 that makes Lydian sound like Lydian. The b2 behind the darkness of Phrygian. · Bridge basic patterns and modal theory, and know which note to lean on · Shapes, not colours, so it stays readable in sunlight and for colour blind players · Understand why a note creates tension or release LEARN THE WHOLE NECK, NOT JUST SHAPES · CAGED View: see one chord in five places and the single finger move that turns each shape into its extensions · Triads Interactive: every three note shape on every string set, with voice leading that shows the shortest move between chords · Layers Mode: put a chord on top of the scale and step through a progression, watching the chord tones move under your fingers · Double tap any chart to open it full screen, then swipe through every voicing, inversion and string set CHORDS, TRIADS AND VOICINGS · A searchable library of every chord type, with inversions and slash chords · Barre markings drawn the way real chord books do it · Triads and arpeggios across every string set · Chord Explorer: place notes and the app names the chord · Save favourites into folders SCALES, MODES AND FRETBOARD MASTERY · Every essential scale and mode, plus exotic and world scales, in clear position boxes · A distraction free full screen view for playing along, with a drone in your key · Chord aware suggestions: see which scales fit the chords you are playing WRITE SONGS, NOT JUST PROGRESSIONS · Progression Studio: start from a proven progression across 23 genres, borrow from modal harmony, or roll a random one that works · Reharmonize any progression brighter, darker or jazzier with one tap · Suggest next chord when you are stuck · Songbook with lyrics, chords above the words, transpose and smart capo · Export a printable song sheet with the chords, scales and arpeggios you chose JAM, IMPROVISE AND RECORD · Build a solo sheet: the scales, positions, arpeggios, triads and voicings for your song, on one page · Backing tracks library with folders, and recording in perfect sync over any track · Adjustable mix, USB-C input support, and a take library to play back and share A TUNER YOU WILL ACTUALLY USE · Fast, accurate chromatic tuning with automatic string detection · Needle, Bar, Strobe and Waveform displays · Adjustable reference pitch, noise filtering, and a left handed mirror mode PRACTISE WITH PURPOSE · Ear training and theory quizzes that level up, with spaced repetition that remembers what you get wrong · Daily streaks that build a habit · A metronome with a tempo trainer, and deep dive theory essays BUILT FOR EVERYONE · Guitar (6, 7, 8 string), bass (4, 5 string) and ukulele, any tuning and capo · Full left handed support · High contrast, bigger tap targets, bold text, reduced motion, Dynamic Type and VoiceOver · 8 languages, iPhone and iPad Download redLUX Guitar and turn practice into progress.
