This update sharpens the interface: the iPad layout now uses a centered, comfortable reading width instead of stretching edge to edge, so every screen reads as a clean column. iPhone is unchanged; still fully on-device.

Chordpeek 2.0 — a pro upgrade for guitarists, still 100% offline. • Metronome with tap-tempo, time signatures, subdivisions, and accents. • Scales & Modes: 11 scales with the chords that fit and per-string fret maps. • Ear Training: graded live by playing the chord you hear. • Practice tracking with a streak, totals, and minutes-by-activity. • Circle of Fifths and related keys. • Progression transposer and a strumming-pattern reference. Plus the same live chord recognition and precision chromatic tuner. No account, no network — every note is detected on your device.

Introducing Tuner Mode — a precise chromatic tuner with a smooth needle, standard and alternate tunings, and an adjustable 432-446 Hz reference, sharing the same on-device listening engine as chord detection. Plus deterministic chord matching and a full accessibility pass.

Keys & Function: when Chordpeek detects a chord live or you view one in the library, a new section shows every diatonic key that chord belongs to, its roman-numeral degree (I, IV, V, vi…), and its harmonic role — Tonic (stable/home), Subdominant (movement), or Dominant (tension). Now you know not just what chord you're playing, but where it lives in the key. Favorites: tap the bookmark icon on any chord in the Library or on the live listen screen to save it. A new Saved filter in the Library shows only your bookmarked chords. Stored locally on your device — no account needed.

30-chord library (up from 12) — now includes major 7th, minor 7th, suspended, add9, and diminished shapes, each with a plain-language description of what the quality sounds like. New Chord Progressions tab: diatonic chords and five named progressions for seven guitar keys, with example songs and tap-through to fingering diagrams. New Capo Calculator tab: find what key you're in from any shape + fret, or find which open-chord shape and capo position produces any key you need.
