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.

KEY FEATURES:
• Hydration logging - quick-add 250 / 500 / 750 ml or a custom amount, with an animated daily progress ring and ml/oz units
• Oxalate food budget - search a curated database of 150+ foods with oxalate values and color-coded tiers, pick a serving size, and log what you eat against your daily budget
• Urine pH log - record readings and view them on a trend chart with your target band highlighted
• Stone-episode timeline - keep a date-grouped, color-coded history of episodes with side, composition, pain level, treatment and notes
• Visual reports - 7-day water, oxalate and pH charts so you can spot patterns at a glance
• Doctor-ready PDF - export a 30-day summary to share at your urology visit (Premium)
• Hydration reminders - optional notifications nudge you to keep drinking through your active hours
• Dark mode and a clean, modern Material design
