Store listing
By Denis Zinin, from the App Store
Description by Denis Zinin Written by the developer, not by AppBrain. Click to read.
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.

No goals.
No streaks.
No diagnoses.
