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.
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.

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.

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.

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.

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.
Pick the exercise of the day and play it in time with the click.
Clean from start to finish? Mark it done. You are the judge.
All 24 done? Raise the bpm and start again — that's your new level.
