About
Renvi is a kidney diet tracker for people who were told to watch potassium, phosphorus, sodium, protein or fluid. Enter the limits your doctor or renal dietitian gave you, then log what you eat and drink — Renvi keeps a running total for the day, so you know how much room is left before dinner.
LOOK UP ANY FOOD
• 6,800+ foods from the USDA FoodData Central database, built into the app — works offline, no account
• Potassium, phosphorus, sodium, protein, calories and water for every food
• Real portions: cups, slices, pieces — or grams
• Browse by aisle: fruit, vegetables, dairy, meat, grains, legumes and more
YOUR DAY AGAINST YOUR LIMITS
• One budget bar per nutrient, filled by each meal
• Breakfast, lunch, dinner and snacks in one list
• Fluid log in ml or oz, including the water already inside your food
• Limits come from you — Renvi does not pick a stage or a protocol for you
RENVI PRO
• Full diary history and 7- or 30-day charts
• A one-tap PDF report to bring to your next appointment
• "Lower in potassium, same kind" swaps for any food
• Your own foods with your own numbers
Renvi Pro is available as a yearly subscription with a 7-day free trial for eligible users or a one-time lifetime purchase. Payment is charged to your Apple ID at confirmation of purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel in your App Store account settings.
Renvi is a food log, not a medical device. It does not diagnose or treat any condition and does not replace advice from your doctor or dietitian. Always consult your care team before changing your diet.
