FretLedger is the guitar log built for players who care about their instruments. Track every guitar, bass, banjo, mandolin, or ukulele you own with a level of detail that no other app comes close to. YOUR COLLECTION, FULLY DOCUMENTED Record make, model, year, serial number, and photos for every instrument. Document hardware specs — bridge type, nut, saddle, tuners, hardware finish, trem block, and strap locks — alongside construction details like fretboard wood, fret wire, neck and body finish, and roasted timber. Log tuning, string gauges, pickup configuration, and wiring for each one. Search and sort your whole collection in seconds. STRING TRACKING THAT ACTUALLY WORKS Set a restring interval for each guitar and FretLedger flags overdue strings automatically. Log brand, gauge, and string type every time you restring. Keep a string inventory to track what packs you have on hand, spot gaps before a gig, and add what you need straight to your shopping list. COMPLETE SERVICE HISTORY Record every setup, truss rod adjustment, fret dress, pickup swap, and luthier visit. Track parts used, costs, and the settings you dialled in. Flag issues as they come up so nothing gets forgotten before the next service. WIRING AND PICKUP DOCUMENTATION Choose from 40+ templates covering Stratocaster, Telecaster, Les Paul, Jazzmaster, Gretsch, and more. Document every control, pot value, and coil split. Track your pickup inventory including stored pickups you plan to reinstall. STRAP COLLECTION Track every strap you own — brand, material, colour, lock type, and photo. FretLedger matches straps to guitars by strap button style so compatible pairings surface automatically on each guitar's overview. Attach a strap to a guitar and the pairing travels with the instrument. All major strap lock systems are supported. SIX LANGUAGES FretLedger is fully translated into English, Spanish, French, German, Italian, and Japanese. Every screen, label, and service type — including all 40+ wiring templates — is localised. The app follows your device's language setting automatically. SHARE AND BACK UP WITH CONFIDENCE Export a branded Guitar Passport PDF to share with a buyer. Send individual guitars or your whole collection as a .fretledger file via AirDrop or Mail. Automatic daily backups keep your data safe across app updates. No subscription. No account. No cloud. Everything stays on your device.
