OurVCP vs KidneyBite

The OurVCP app is being used for a VCP app and wearable study conducted by 4YouandMe - a digital health non-profit organization in partnership with Cure VCP Disease Inc., and funded by the Chan Zuckerberg Initiative. This prototype app is 1 of 5 apps that are being tested as part of a larger rare and unique disease study that aims to co-design and pilot test symptom tracking and transmitting apps alongside wearable devices across 5 different conditions including VCP disease, Pancreatitis, Long COVID, Sarcoidosis, and Primary Ciliary disease. Each of these conditions present unique symptom profiles across individuals that span symptoms of cognitive disturbances, pain, fatigue, cough, autonomic changes, respiration changes and mental health burden that are unique to each individual. This study aims to work with participants as co-designers to beta test an app and wearable experience that is intended to work like a compass to empower individuals to follow their unique symptom trajectories in passive and active ways, better understand what makes their condition better or worse and provide more accurate information for clinicians. If you decide to participate, after having a conversation with a 4YouandMe representative, you will download this study app where you will be fully informed of the study details and sign a consent form agreeing to participate. This app will serve as a hub for study participation. Using this app, you can track your study progress, complete surveys and tasks, and connect other mobile apps and wearable/smart devices that will be provided to you that will include an Oura smartring, an Applewatch and a MIR Smart One Spirometer. You will be asked to use the study app and wear and use the provisioned devices for 5 months and communicate with a 4YouandMe Engagement Specialist every 2 weeks to discuss your experience. We expect that using the app for the study will take less than 5 minutes daily. This study has been reviewed and approved by an Institutional Review Board (Advarra).

KidneyBite helps you understand what’s on your plate when you live with chronic kidney disease. Snap a photo of your meal. KidneyBite identifies foods, estimates portion sizes, and shows you four kidney-relevant nutrients: • Phosphorus • Potassium • Sodium • Protein Every estimate is personalized to your CKD stage (1 through 5, plus dialysis), so the score you see reflects your daily targets instead of generic nutrition guidelines. WHY PHOSPHORUS Phosphorus is one of the hardest nutrients for kidney patients to track because it rarely appears clearly on food labels. KidneyBite uses phosphorus data from the USDA FoodData Central database — a trusted public nutrition database — and surfaces it for every meal you scan. HOW IT WORKS 1. Take a photo of your meal. 2. AI identifies foods and estimates portions. 3. See your KidneyBite Score with a Low, Moderate, or High caution estimate personalized to your CKD stage. 4. Tap Log Meal to add it to your daily totals. KIDNEYBITE PRO Unlock Pro to access: • 25 scans per week (Weekly) or 100 scans per month (Annual) • Detailed nutrient breakdowns • CKD-stage-aware targets and trends • Full meal history • Weekly charts for phosphorus, potassium, sodium, and protein • Doctor-ready PDF reports • Apple Health sync FREE PLAN • 5 lifetime meal scans • All CKD stages selectable • Basic nutrient estimates • Last 3 meals saved in history PRIVACY-FIRST Your meal photos are sent securely to our AI provider for analysis only and are not permanently stored on our servers. Your history stays on your device. Apple Health sync is always optional and only writes data if you enable it. Your health data is never sold or used for advertising.
