01 — The method

One drill a day, and you decide when it counts.

The exercise of the day is one of the 24 finger permutations of the spider — four fingers, one per fret, across all six strings. Play it in time for at least your minimum, then check it off only when it's clean. The app doesn't listen and doesn't grade you.

Exercise of the day

Take the drill. Play your minimum. Check it clean.

One of 24 permutations, the metronome running, a self-assessed checkmark. The diary counts the day only when you mark at least one exercise done — you are the judge.

Demo mode

A demo that can't drift out of time.

Press Demo and hear the exercise played for you, perfectly with the click — like a teacher playing it first. The fretboard lights the note you're hearing, so eye and ear learn together. One ascent, one descent, then it stops by itself.

Demo mode: the fretboard lights up each note as the synthesized string plays
The diary

A diary made only of the days you showed up.

Every checked exercise becomes an entry: training day, actual time to the second, bpm and subdivision. No streaks to guilt you, no missed days on record — just the work you did.

The guide

The spider, explained fret by fret.

Position 1, one finger per fret, all six strings, up to the 12th and back. The built-in guide and the demo show exactly how it should sound — then it's your turn.

02 — The set

Twenty-four permutations. Then raise the tempo.

Every ordering of the four fingers — 1 index, 2 middle, 3 ring, 4 pinky. Clear all 24 at a tempo and that becomes your new level. This is the whole set.
