Whether you own two guitars or a full touring rig, String Ledger keeps everything organized, documented, and protected. CATALOG YOUR COLLECTION Add every instrument and piece of gear you own. Log brand, model, nickname, year, serial number, color, country of origin, storage location, purchase price, and current value. Attach multiple photos to each instrument, pinch to zoom in on details, and save any photo back to your library. TRACK STRINGS & MAINTENANCE Never lose track of when you last changed your strings.
