Run+ provides a delightful and magical workout experience optimized for Apple Watch with AirPods! Run+ represents a giant leap forward in technology that provides real time personalized coaching using an advanced artificial intelligence system that adapts to daily changes in your health & fitness to help maximize your training & performance. Run+ alerts you to critical data: climbs on your run route, drifting out of the target speed, heart rate, cadence, or effort for your workout, new best times or efforts, when you should hydrate & fuel for optimal performance, and acute or chronic fatigue limits indicating that you should stop to minimize the risk of injury. Additionally, it speaks a summary of your current data when you raise your wrist and provides motivational feedback at critical points throughout your workout. Run+'s intelligent audio feedback allows you to center your focus on the terrain and the effort of your workout, without the distraction of glancing down at your Watch screen to see your data. Because the artificial intelligence algorithms that power Run+ execute directly on your Watch, you get both faster, more immediate coaching during your workout, and your privacy & data security is ensured because your data never leaves your Watch for processing on a distant cloud server.

Take control of your kidney diet — and know exactly how you're doing, every day. KiddiAI is built around a daily Renal Balance Score (RBS) — a personalized 0–100 rating across protein, sodium, potassium, phosphorus, and fluid, tailored to your CKD stage. YOUR DAILY RENAL BALANCE SCORE The RBS combines your intake across all five kidney-critical nutrients into a single score, personalized to your CKD stage (1–5), dialysis type (hemodialysis or peritoneal dialysis), and any additional restrictions like fluid or sodium limits. Four tiers tell you exactly where you stand: • Optimal — keep it up • Stable — good, with room to improve • Caution — adjust today's choices • Alert — review your intake today Watch your 3-day trend to see if you're improving over time. Hit Optimal? Celebrate with confetti. 3-DAY DIET ANALYSIS Get an AI-powered summary of your eating patterns across the last 3 days — with specific observations and suggestions tailored to your kidney diet profile. FOOD JOURNAL THAT WORKS FOR YOUR KIDNEYS Unlike general food trackers, KiddiAI tracks the nutrients that actually matter for kidney disease. Your food journal is organized by meal type (breakfast, lunch, dinner, snacks), with dietary tags so you can instantly see which foods are high or low in the nutrients that matter. • Search thousands of foods from the USDA FoodData Central database • Barcode scanning for packaged foods • Voice input — just say what you ate • Recently logged foods for fast repeat entries • Kidney Safety Indicator — every food shows a color-coded label (Safe / Caution / Avoid) based on CKD-relevant nutrients • Quick fluid logging — add water from the dashboard or journal in one tap AI FOOD ANALYSIS Not sure what's in your meal? Snap a photo. KiddiAI uses advanced AI to identify foods and estimate their nutritional content — including potassium, phosphorus, and sodium — so you can log complex or restaurant meals without guessing. BUILT FOR YOUR KIDNEY CONDITION KiddiAI adapts to your specific situation: • CKD stages 1 through 5 • Hemodialysis and peritoneal dialysis • Fluid restriction (CHF / edema) • Kidney stone prevention diet • Custom nutrient limits set by your care team Set your profile once. Every score, tip, and limit adjusts automatically. DAILY DIET ADVICE Each day, KiddiAI surfaces personalized diet tips matched to your CKD profile — covering potassium, phosphorus, protein, sodium, and fluid management. Practical, kidney-specific guidance, not generic nutrition advice. STAY MOTIVATED • Logging streak — track your current and longest consecutive days • Meal reminders — set customizable post-meal nudges for breakfast, lunch, and dinner • Nutrient progress rings and calorie visualization • 3-day RBS trend view 1 MONTH FREE TRIAL Try every feature free for 1 month. No commitment required. After the trial, a subscription keeps all premium features — food logging, AI analysis, and your full score history — available without limits. KiddiAI is a dietary tracking tool and is not a substitute for medical advice. Always follow the guidance of your nephrologist or registered renal dietitian.
