About this app
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 INTELLIGENT FEATURES Smart Contextual Reminders → "It's 2pm and you're at 40%—drink 500ml now" → "You logged spinach but didn't pair calcium" → "Tomorrow is 95°F—your target increases to 3.0L" Stone-Safe Meal Library → 30+ pre-built meals with calcium pairing done for you → One-tap logging—no calorie counting → Filter by breakfast, lunch, dinner, or snacks Daily Stone Risk Score → 0-100 score based on today's adherence → Track improvements week over week → Motivating gamification that actually works Heat Day Protection → Weather-aware hydration targets → Automatic adjustments on hot days → Never get dehydrated in summer 7-Day Friend Challenges → Accountability with friendly competition → Private progress sharing (friends see % only) → Stay motivated together Apple Health Integration → Auto-sync from smart water bottles → Works with HidrateSpark, Thermos Smart Lid → Zero manual logging required WHAT UROLOGISTS SAY "I recommend Oxal AI to all my kidney stone patients.
