More → Resources has a tuner and a music library to learn from as you write — all of it works offline.

  1. Tuner: for guitar, bass, ukulele, mandolin, banjo, violin, viola, cello, double bass, brass, woodwinds and your voice, in every common tuning (drop and open tunings too). It reads low strings at their own octave and holds the needle steady while a note rings.
  2. Instruments: scales, chords and triads on every string instrument and the piano, and fingering charts for brass and woodwinds (oboe and bassoon too) — tap a note to hear it played on that instrument.
  3. On a bass or double bass, Chords → Bass Lines & Shapes shows root–fifth–octave, chord tones and a walking line. On a banjo, Chords → Banjo Rolls writes out the four rolls.
  4. Music Theory → Harmony: what each chord in a key does, how to harmonize a melody, how chords move, and what to play over them when you jam.
  5. Music Theory → Common Progressions: more than 50 chord progressions, with what each one feels like, in any key.
  6. Progression Builder: build your own (borrowed chords too), tap a chord to make it a 7th or sus, and tap Use in My Song.
  7. Nashville Numbers & Transposing: chords as numbers, a song moved to any key, and where to put a capo for easy shapes.
  8. Reading: Song Form, Reading Chord Charts, Reading Sheet Music, Reading Rhythms (tap Play to hear each one counted in) and Reading Tab.
