About Kidni – Kidney & Dialysis
Kidni supports you through every phase of chronic kidney disease – from pre-dialysis through peritoneal dialysis and hemodialysis to transplantation. The app adapts to your phase and shows exactly the tools you need right now. Built by a kidney patient – for kidney patients. YOUR PHASE, YOUR APP • Pre-dialysis: keep blood pressure, fluid intake and appointments in view – so you can shape the course of things yourself. • Peritoneal dialysis: log exchanges with time, ultrafiltration and effluent colour – warning signs included. • Hemodialysis: plan clinic appointments and record each session with weight, pulse and symptoms. • Transplantation: take immunosuppressants on time – with a time-critical alarm that cannot be swiped away. EVERYTHING KIDNI DOES • Daily overview: medication, fluid, weight and blood pressure for the day on a single screen. • Nutrition: track potassium, phosphate, sodium, protein and fluid – daily rings show at a glance where you stand. • Foods: a nutrient database, a barcode scanner and your own foods for anything that is missing. • Recipes: 214 kidney-friendly dishes with full nutrient values – added as a meal in a single tap. • Fluid: a water tracker with your personal daily limit. • Lab values: record creatinine, GFR, potassium, phosphate and more and see them over time. Import your lab report as a PDF – the values are detected automatically. • Medication: reminders for every medication, time-critical if you want. • Vitals: log blood pressure, pulse and weight – synced with Apple Health if you allow it. • Dialysis diary: every exchange and every clinic session on record. • Appointments: doctor and dialysis appointments with a reminder and an entry in your calendar. • Report: PDF or CSV with your values and trend charts – ready to share with your practice or clinic. • Limits: set your own targets for potassium, phosphate, sodium, protein and fluid. • Kidney guide: 65 articles from diagnosis to transplantation, searchable and offline – with an emergency card. • Ten languages, light and dark mode. YOUR DATA • No account, no registration, no tracking of your health data. • Your entries stay on your device; syncing runs through your own iCloud. • Complete deletion at any time in the settings. Note: Kidni does not replace medical advice and does not make diagnoses. Always discuss limits, medication and nutrition with your care team. KIDNI PRO The full nutrition feature, lab value tracking and the ad-free app are part of Kidni Pro – an auto-renewable subscription, monthly or yearly, both starting with a free trial period. Price and length are shown in the app before you buy. Payment is charged to your App Store account at the time of purchase. The subscription renews automatically until you cancel it – you can do that at any time in your App Store account settings.
