Store description excerpt
FretTools Gear Tracker. String Diagnostics. Tuner. Chord Library. GEAR TRACKER Your gear documented and accessible when it matters. • Track guitars, basses, amps, pedals, and more • Store serial numbers, specs, purchase details, values, and notes • Attach photos to each item • Record string changes with brand, model, gauge, and date • Log maintenance, repairs, setups, and modifications • Export a formatted PDF with gear details for insurance or resale STRING DIAGNOSTICS Know what's happening inside your strings, not just what note they're on. FretTools analyzes six harmonics in real time using phase-shift detection — the same moment you'd normally just tune to also tells you whether a string is going dead, sitting out of intonation, or due for a change. • String Health evaluates tuning stability and harmonic agreement • Intonation analysis helps reveal possible setup inconsistencies • Harmonic Lanes for detailed pitch analysis • Save diagnostic history to a selected instrument • Compare readings across the life of the current string set • Start a new session when you log a string change String Diagnostics is a Pro feature. It runs on the same pitch engine as the free tuner below, but it's a separate capability — most tuners tell you a note. None of them tell you your string is dying. String Diagnostics provide guidance and do not replace a full instrument inspection or professional setup. TUNER — FREE. ALWAYS. Responsive, accurate tuning for guitar, bass, ukulele, banjo, mandolin, violin, and more. • Real-time note and cents display • Strobe-inspired ring for clear sharp/flat feedback • Instrument-specific tuning presets CHORD LIBRARY Find chords quickly across multiple guitar tunings, ukulele, and mandolin. • 2,500+ chords with 3,200+ voicings • Clean diagrams with finger positions • Open chords, barre chords, inversions, and alternate voicings • Slash chords with alternate bass notes • Browse by root, chord type, category, or key • Diatonic chords grouped by harmonic function • Play full chord strums • Tap individual notes to hear them in isolation WHY FRETTOOLS • Four practical tools in one app • Works offline • No account required to get started • Clean, focused interface • Built for working musicians and hobbyists alike FREE → PRO The Tuner is unlimited and always free.
