About StoneGuard: Kidney Stone Care
StoneGuard helps people who have had kidney stones with the two things urologists ask for most: drink enough, spread over the day, and know what is on the plate. TODAY • A glass that fills as you log. The big number is what is still missing, not a percentage. • A dashed line shows where you should be at this time of day, so you can drink evenly instead of catching up in the evening. • One tap for 200, 300 or 500 ml, or any amount. • Daily goal based on weight, activity and the local temperature (Apple Weather). LOCK SCREEN AND DYNAMIC ISLAND • See what is left and log 250 or 500 ml without opening the app. • Home screen widget and Siri: "Log water in StoneGuard". FOOD • 225 foods with oxalate per serving, the source of each value and lower-oxalate alternatives. • Search in English, German, Italian or Spanish, filter by level and category. • Notes on purines, salt, citrate and calcium where they matter. LOG FOR YOUR APPOINTMENT • Urine log with colour, clarity, pH and symptoms. • Voiding diary with intake, output and urgency. • Stone log: diagnoses, passages, procedures, stone type. • 24-hour urine results with each value compared to typical stone-clinic targets. • PDF report for your doctor. PRIVACY • Your health data stays on your device. iCloud sync is optional; the health values are end-to-end encrypted. • Optional app lock with Face ID. STONEGUARD PRO Voiding diary, PDF report, lab results, food alternatives and favourites, unlimited supplements and urine logs, 30-day statistics and iCloud sync. Available as a monthly or yearly subscription or as a one-time purchase. StoneGuard is a diary and information tool. It does not diagnose or treat any condition. Talk to your doctor about your diet and fluid intake, especially if you have heart or kidney disease. Terms of use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
