Oxal AI
Kidney Stone Prevention
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Kidney stone prevention that actually works. Oxal AI uses clinical guidelines to stop calcium oxalate stones with personalized hydration targets, smart sodium tracking, and calcium-oxalate pairing—the three strategies urologists recommend.
94% OF USERS STAY STONE-FREE
If you've passed a stone, you know the pain. Oxal AI helps you prevent the next one—without food diaries, barcode scanning, or guesswork. Our users average 14+ months stone-free vs. the typical 50% recurrence rate.
HOW OXAL AI PREVENTS STONES
Most apps just remind you to drink water. Oxal AI targets the three proven prevention factors:
▸ Personalized Hydration — Hit 2.5L urine output based on your body weight, activity, and local weather—not generic "8 glasses"
▸ Smart Sodium Tracking — Stay under 2,300mg daily without weighing food or scanning barcodes
▸ Calcium-Oxalate Pairing — Get instant prompts to pair high-oxalate foods (spinach, almonds, chocolate) with calcium at the same meal
