Bladder Diary: Fluid Balance support

Yes, the app is free. Logging, the daily summary, the statistics grid, widgets, Apple Watch, iCloud and CSV export are free for as long as you use it. Pro is an optional one-time purchase that adds the PDF report and the advanced charts. There is no subscription, and nothing ever interrupts an entry to ask you to upgrade.

No. There is no sign-up, no name, no birthdate. Open the app and start.

Two buttons and a list of amounts. There is nothing to set up.

The time, what you drank and how much, what you passed or a Not measured tick, whether it was a night trip, and a note if something happened. There is a longer guide with a worked example: how to keep a bladder diary.

As many as you were asked for. Most clinics want three to seven full days, and a complete short diary is worth more than a long patchy one. Where those numbers come from: how many days is enough.

Apple Watch: the same presets and Not measured, with the day's IN, OUT and BALANCE. iPhone with iOS 18 or later, iPhone Duo included — on the wide screen the diary is laid out for it. On an iPad the app runs as an iPhone app for now; full iPad support is coming in a later update.

English, German, French, Spanish, Italian, Portuguese (Brazil), Russian, Japanese, Korean, Simplified Chinese, Traditional Chinese, Polish, Swedish and Czech — 14 in all. The PDF report is translated too; CSV stays in English.

An estimate. A missed entry is worse than an inexact one, and nothing in the app marks your data as unreliable. If you did not measure at all, use Not measured — it counts towards frequency and night events, and stays out of volume totals. The jug, the toilet hat and estimating: how to measure urine output at home.

Yes. Open the entry and change the time, the type or the volume, or add a note.

Urgency, yes. Turn the urge rating on in Settings and every output entry can be rated from 0 to 4; it shows in the diary, on a chart, in the PDF report and in CSV. It is off by default, so an entry stays two taps unless you want it. Leaking has no field of its own — put it in the note on the entry. What to put in the note, and how clinic forms score urgency and leaks: bladder diary for overactive bladder and leaks.

No. There is an optional reminder to fill in the diary — off by default, you pick the time. It comes only on days with no entries, and pauses after a week without any. Its text never names what the app is about, so it gives nothing away on a locked screen.

Yes. While today has no entries yet, a card on the Today screen shows yesterday; one tap opens that day.

Yes, 12- or 24-hour time, whichever you prefer. The setting is in Settings.

Never. You only see Pro when you open the report or the advanced charts.

CSV export, from Settings, over your whole history, without restriction. The PDF report (Pro) is laid out the way a bladder diary is normally read.

Yes. The PDF can be printed, shared, emailed, or shown on your phone.

On your device, and in your own private iCloud database if you turn iCloud on. There is no server and no account. Export a CSV any time for your own backup. See the Privacy Policy.

Settings, Delete all data. One step, one confirmation. It clears the device and, if enabled, your iCloud copy.

No, and it never will. It records what you tell it and shows you the totals. No goals, no norms, no warnings, no advice. Interpretation belongs to your doctor. What a clinician reads in the diary: what does a bladder diary show.

The PDF report, the Advanced analytics page (the first weekly chart is free) and the dark app icon. One-time purchase, nothing renews.
