About

Magic Kidney

Read full description

One photo of your meal is all it takes. Magic Kidney's AI estimates sodium, potassium, phosphorus, and protein, then compares them to the limits for your CKD (chronic kidney disease) stage. What makes it different β€” it's built on Korean foods and the Ministry of Food and Drug Safety (MFDS) nutrition database, tuned for Korean meals from kimchi stew to bibimbap. β–  Key features β€’ Photo analysis β€” snap a meal and the app separates the dishes and estimates four nutrients. β€’ Today's budget β€” compare against sodium, potassium, phosphorus, and protein limits matched to your CKD stage and body weight, in real time. β€’ Chat with your buddy β€” ask about foods and nutrients; answers are grounded in the app's food database. β€’ Medical report PDF β€” summarize recent meals and lab values to share with your doctor. β€’ Smart reminders β€” meal, medication, and check-up reminders, with an instant heads-up when sodium nears your limit. β€’ Nutrition-label scan β€” photograph a packaged-food label to auto-fill its nutrients. β€’ Blood-test log β€” estimate your CKD stage from eGFR and keep your kidney numbers in one place. β€’ 30 & 90-day trends β€” see how your nutrients flow over time. β€’ Your journey, My Foods, Salt meter β€” stay motivated to log, save frequent foods, and precisely enter salt in soups. β–  For people with CKD No scary scores. Instead of "dangerous," we explain "why," and when you go over a limit we tell you without blame. β–  Privacy Your records stay on your device. Food photos are used only briefly for nutrition analysis and are not stored. This app is an informational and self-management tool providing AI estimates β€” not medical advice, diagnosis, or treatment. Always discuss diet and treatment decisions with your healthcare provider.
