String Hours

String Hours is a simple tennis string usage tracker.

Track when your racquet was strung, log each play session, and see how many hours are on your current string setup. Set your own min, best, and max usage targets so you know when your strings are fresh, in their best range, past their best, or ready to replace.

Features:
• Track your current tennis string setup
• Log play sessions by date, duration, and play type
• See total hours used
• Set min, best, and max hour targets
• Use simple status guidance: Fresh, Good range, Past best, Replace soon
• Local-only storage with no login required

String Hours is built for tennis players who want a lightweight way to track string life without a complicated racquet management system.
