Kidney Stone Tracker

Kidney Stone Tracker is a simple, offline health logger that helps you stay on top of the everyday habits linked to kidney stone prevention: drinking enough water, watching your oxalate intake, keeping an eye on urine pH, and keeping a clear record of your stone history. Everything you log stays on your device.

Whether you have had a stone before or simply want to build better hydration and diet habits, this app gives you an organized, private place to track what matters and to share a clean summary with your urologist.
