Music
Free
Six practice tools for guitar — tuner, metronome, chord library, fingerstyle trainer, fretboard drills, and real song riffs. No subscriptions, no streaks to keep up.
Celestial Strings is a practice companion for guitar — six focused tools, no subscription, no streaks or badges nagging you to keep a habit alive. Just the instruments you actually reach for between practice sessions.
ORACLE — TUNER
Real-time pitch detection built on the McLeod Pitch Method, tuned by ear against a Python reference implementation before a line of Swift shipped. Works for any tuning your instrument uses, with a capo control that shifts what counts as "in tune" without changing which string you're touching.
PULSE — METRONOME
A clean, accurate metronome with every time signature you'd actually use, swing subdivisions, and a tempo that's remembered the next time you open it.
CODEX — CHORD LIBRARY & FRETBOARD
Every common chord — majors, minors, sevenths, sus2/sus4, add9 — with real, hand-verified fingerings, not algorithmically nearest-fret guesses. Explore the fretboard note by note, or drill chord changes against a real strum pattern (down-up, pop-rock, reggae skank, and more) at your own tempo.
LOOM — FINGERSTYLE TRAINER
Learn and practice fingerstyle patterns with a hand diagram that shows exactly which finger plucks which string, in real time. Build your own patterns in the custom editor, or start from patterns you already know.
TRIALS — FRETBOARD TRAINER
Name the note at a given fret, cold. The fundamental skill under every other room, drilled directly.
RIFFS — SONG LIBRARY
Real riffs, transcribed accurately — down to the bends, pull-offs, and slides — not simplified stand-ins. Play along at your own pace.
No accounts. No ads. No streaks. Just an instrument's worth of tools, built by a guitarist who wanted them to exist.
