Dead strings kill your tone. GearKeeper tracks every instrument in your rack — electric, acoustic, bass, drums — and tells you exactly how many days you've been on the current set. • Per-instrument change history with brand & gauge • "Logged a fresh set" one-tap reset • Freshness badges so you can see the whole rack at a glance • Reminders tuned to how hard you play GearKeeper Pro ($11.99/yr): unlimited instruments, string-life stats by brand, per-instrument gauge presets. Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period; manage or cancel it anytime in your App Store account settings.
