Keep a complete I&O chart for the person you care for — intake, output, vitals, and the medical background that puts it all in context.

WHAT YOU CAN TRACK • Intake — oral, G-tube, central-line fluids, and TPN • Output — urine, stool, emesis, G-tube drainage, and ostomy output • Irrigation — with automatic net calculation • Vitals — weight, height, temperature, heart rate, blood pressure, respiratory rate, oxygen saturation, blood glucose • Activities and symptoms alongside the numbers MEDICAL HISTORY Record a patient's baseline in one place — a summary of their typical day, diagnoses, feeding tubes and central lines, ostomies, allergies, and care notes. It sits alongside the daily log, keeping important background close to today's numbers. LOGGING THAT KEEPS UP WITH YOU • Quick entry buttons for anything you log repeatedly — one tap, pre-filled • Progressive forms that adapt to what you are recording • Automatic unit conversion between metric and imperial FLUID BALANCE AT A GLANCE • Today versus yesterday intake and output • Time-based volume analysis • Weight and growth trends • Calendar-day or TPN-day display modes REPORTS FOR YOUR CARE TEAM Filter every recorded event by date, type, or category, and export a clean report to bring to an appointment or send to a provider. YOUR DATA Your data is encrypted in transit, and your credentials are stored in the iOS Keychain. The app does not maintain a local patient-record database. We never sell patient information or use it for advertising. You can delete your account and its data at any time.

Keeping a bladder diary probably isn’t the most exciting part of your day. So we made it take as little time as possible. Intake → amount. Output → amount. Two taps. Logged. Fluid Balance is built for a simple bladder diary over a few days — usually 3–7, or longer if needed. Log as you go, see the full picture, and share it with your doctor when you’re done. TWO TAPS. DONE. Tap Intake or Output, then choose an amount. That’s it. No required notes. No questionnaires. No long forms. Log from your iPhone, Home Screen widget, or Apple Watch. Not sure about the exact amount? Estimate it. Consistent entries are usually more useful than trying to remember everything at the end of the day. YOUR WHOLE DAY AT A GLANCE Open the app and immediately see: • total intake • total output • current balance • every entry from the day, in order Edit or delete any entry in seconds. If needed, you can also track urgency on a scale from 0 to 4. A REPORT FOR YOUR DOCTOR Choose any date range and create a PDF report. It brings together voided volumes, times, daily totals, nighttime events, and other useful bladder diary data in one place. Print it, send it, or simply open it on your phone during an appointment. Need the raw data? CSV export is available too. STATISTICS Review your diary by day and explore your data with charts for: • intake and output • voids per day • nighttime voids • time between voids • patterns throughout the day Just your data — without trying to judge it for you. No “good” or “bad” days. No goals. No streaks. No diagnoses. WHY PEOPLE KEEP A BLADDER DIARY A bladder diary may be used for nocturia, overactive bladder, incontinence, fluid balance monitoring, follow-up after treatment or surgery — or simply because your doctor asked you to keep one.
