System Overview & Specifications

Musicians, hobbyist guitarists, and ukulele players need an accurate chromatic tuner, chord library, and metronome when playing at campfires, rehearsals, or in the garage. Mainstream tuner apps (GuitarTuna, Ultimate Guitar) charge $40–$70/year subscriptions, force social accounts, and bombard players with paywalls. ChordTuner Pro features 0.1Hz precise FFT on-device pitch detection, full alternate tunings (Drop D, DADGAD, Open G), 2,000+ interactive chord diagrams, and a tap tempo metronome 100% offline. Core Features: • Chromatic FFT Mic Tuner: Sub-cent real-time pitch detection with smooth needle display and octave readout • Alternate Tuning Presets: Standard E, Drop D, Half Step Down, Open D, Open G, DADGAD, and Ukulele Standard (GCEA) • 2,000+ Interactive Chord Diagrams: Major, minor, 7th, sus4, diminished with exact finger positions and audio playback • Tap Tempo Metronome: 30 to 300 BPM with customizable time signatures (4/4, 3/4, 6/8) and visual pendulum • Campfire Transposer: Instant 1-tap pitch transpose for singer-songwriters matching vocal ranges • 100% Offline & Ad-Free: Zero internet permissions requested, zero tracking 100% Offline • 75% Less Than Mainstream Subscriptions • Zero Cloud Accounts Required.
