Bladder Diary: Fluid Balance

Track what you drink and what you pass. Two taps, no typing.
Built for the 3-7 day diary your doctor asked for.
No account, no ads, nothing leaves your phone.

TWO TAPS, NOTHING IN BETWEEN

Tap + Intake or + Output, then tap a preset. The entry is saved. No forms, no keyboard, no waiting. Presets cover the usual amounts, and a custom field is one tap away when you need an exact number.

Not sure of the volume? Estimate it. A missed entry is worse than an inexact one, and nothing in this app marks your data as unreliable.

YOUR DAY AT A GLANCE

IN, OUT and BALANCE sit at the top of the screen the moment you open the app - no scrolling. Below them, the day's entries in order, each one editable, or removed with a swipe.

A REPORT YOUR DOCTOR CAN READ

Pick any range and export a PDF laid out the way a bladder diary is normally read: daily totals, individual voided volumes, times, night events, and the averages a urologist looks for. Print it, or bring it on your phone.

CSV export is there too, at any depth of history, so your numbers stay yours.

WHAT THE STATISTICS SHOW

A month grid of the days you logged, counters for entries and days tracked, and - under Advanced analytics - intake and output by day, volumes by hour, night events over time, and the distribution of voided volumes.

Numbers only. No goals, no streaks, no norms, no warnings, no advice.

PRIVACY BY CONSTRUCTION

There is no server. Entries live on your device and, if you turn on iCloud, in your own private iCloud database - the one only you can read. No account to create, no analytics, no crash reporting, no advertising, no third-party code of any kind.

Erase everything from Settings in one step, whenever you want.

WHAT THIS APP DOES NOT DO

It does not diagnose. It does not compare you to a norm. It does not interpret your entries or tell you what they mean. It does not remind you to drink.

It records what you tell it, and it hands the record back to you.
