Instant progressions
Pick a key and a vibe — get a strong chord progression to play over immediately, with two guitarists soloing within seconds of sitting down.
Built for guitarists, by a guitarist
Two guitars. Zero rehearsal. Instant music.
redLUX Guitar builds a strong chord progression in any key in seconds, so you and a friend can start jamming original music the moment you sit down — no shared setlist required. From that first jam, grow it into a full song with lyrics, scales, and a complete practice studio. Entirely offline. No accounts. No ads.
A complete creative studio
From the first chord to the finished song
Everything that happens between picking up a guitar and finishing a song — built into one focused, glare-friendly app for late-night sessions.
Intuitive scale maps
Every mode builds on the pentatonic shape already in your fingers — flavor notes appear as triangles you can spot without looking, so a new mode never feels like starting from zero.
Songwriting & lyrics
Turn a jam into a real song. Add lyrics, organize your originals, shuffle your repertoire, and share when you're ready.
Improv & arpeggios
Combine scale positions, arpeggios, triads, and custom elements to practice exactly what you want to master.
Tuner, metronome & record
An accurate tuner, a metronome with real drum grooves, and the ability to record over your own backing tracks.
Everyone's instrument
Left-handed mode, 7- and 8-string guitars, bass, and ukulele — fully supported, not bolted on.
"I built the tool I always wished existed—something I'd rely on every night, even in the middle of nowhere. No signal. No excuses. Just creation."
— Frank, creator of redLUX Guitar
