Version 1.0

Everything you need to capture a riff

No DAW clutter — just tab, timing, techniques, and songs that stay on your device.

Tab composer

Tap the fretboard, pick note lengths, add hammer-ons, bends, slides, and repeats — with a live tab staff below.

Song library

Save titles, artists, key, and BPM. Search your catalog, mark favorites, and open any song in a glance.

Print your score

Print landscape tab from the composer or library — ready for the music stand or a PDF archive.

Guitar tuner

Chromatic tuner with standard and alternate tunings, auto or manual string select, and a clear cents meter.

Screenshots

Built for Mac. Ready for iPad.

Dark UI, cyan accents, and a workflow that stays out of your way while you write.

Barlines and measure structure in the composer
Structure & barlines Time signature, measure boundaries, and editing tools that keep your rhythm honest.
Tab score with hammer-ons, pull-offs and bends
Expressive notation Hammer-ons, pull-offs, bends, and rhythm stems — readable tab, not a plain number grid.
