It’s designed for people with urological conditions, pregnant women, athletes, and anyone who wants to monitor their health. You can enter data manually or collect it automatically using compatible devices. The app analyzes your data, highlights potential irregularities, and helps you track trends over time. Flexible reports make it easy to share information with your doctor for evaluation and treatment adjustments. Reminders help you stay consistent with logging, while the intuitive interface keeps everything simple and clear. The app does not require any external devices to function — they are optional and can be used to simplify data entry (for example, by automatically transferring readings).

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.
