## What is Instrument String Log?

Instrument String Log keeps string maintenance organized for every instrument you own.

Record each string change, choose a common gauge set, and see which instruments are approaching their next replacement. Inventory tracking also helps you know whether a spare set is ready before rehearsal or a gig.

FEATURES

• Manage guitars, basses, ukuleles, violins, cellos, and other instruments
• Choose common string gauges or enter a custom gauge
• Record replacement date, reason, brand, product, and notes
• See last change, next target date, days remaining, and replacement status
• Track spare-string inventory and low-stock alerts
• Review and edit complete replacement history
• Add an instrument photo for quick identification
• Optional local reminders based on usage frequency
• English and Japanese interface, following the iPhone language setting

Your instrument records and photos stay on your device. No account is required.
