iUFlow is a starting point for a free intake-and-output diary; Bladderly offers manual and optional sound-assisted logging, with paid features to check. Squeezy includes a diary alongside pelvic floor exercises. Choose the record your clinician needs and a format you can keep using. Logging alone is not bladder training.

A diary and bladder training do different jobs
A bladder diary records what happened: toilet trips, drinks and other details your clinician asks for. Bladder training is a treatment approach. A graph showing yesterday's visits doesn't tell you how long you should wait today or establish why you're going frequently.
If a clinician has asked for a diary, start with their requested details and format. Otherwise, you can end up with a beautifully coloured chart that doesn't answer the question at your appointment.
iUFlow: a free diary
Start here if you want to explore a free intake-and-output diary. iUFlow's provider describes recording drinks, urine output and bowel activity, with records you can share with your clinician. It links to both iPhone and Android, and we confirmed a UK iPhone listing.
The provider describes the app as free. Its optional urine-flow hardware is a separate product; you don't need that hardware simply to use the manual diary. Don't confuse a manually entered amount with a device measurement.
We haven't completed an in-app sample report. Before relying on it for an appointment, try a clearly labelled practice entry, see how correction works and check the report shows the dates and units your clinician needs. Remove the practice entry from your real record.
Bladderly: manual or sound-assisted logging
Consider it if you want to compare manual logging with an optional sound-assisted approach. Bladderly's current description focuses on recording bathroom visits and timing. Its sound feature estimates voided volume; it also supports manual entry.
That estimate is not a diagnosis or automatically equivalent to a measured volume. If your clinician has asked you to measure output, check whether estimates are acceptable for the particular record they're requesting.
The UK store lists a free download with in-app purchases, including £1.99 for export and £4.99 for a three-day pass, as well as subscription products. Those listed purchases don't establish exactly what a new user receives free or which purchases are alternatives. Check the current in-app offer before starting a diary you need to export.
We've verified the UK iPhone listing, not an Android UK offer. The developer describes the product as tracking and record-keeping support, rather than diagnosis or treatment.
Squeezy: diary and exercise prompts
Consider it if you also need support following pelvic floor exercises. Squeezy's UK listing includes a bladder diary alongside an adjustable exercise routine, audio and visual prompts and reminders.
At £3.99 on the UK iPhone store, it may be useful if you already want those exercise features. But don't buy it just to avoid using two apps unless its diary captures what you need. We haven't tested its fields or export format for this comparison.
If you only need a record of toilet trips, start by comparing diary functions. If pelvic floor exercises are also part of your agreed plan, our stress-leakage guide explains the routine-support differences.
A paper diary from your clinic
Use this if it is the format your clinician wants and it works for you. A clinic-provided form can be a sensible baseline: you know which details have been requested and don't need to discover an export charge later.
The trade-off is manual recording and keeping the form handy. If that means you forget entries, a phone diary may fit better. Ask whether the service can use the app's report before you spend several days filling it in.
Make logging a small job
One request from the OveractiveBladder community gets straight to the practical problem:
I need something very simple.
Everytime I go to toilet, I would press a button on this app (with no more additional options).
Then it will show me a report of how many times, I use toilet everyday.
Anonymous Redditor, r/OveractiveBladder discussion
That is a request for low-effort logging, not a clinical recommendation. It suggests a useful way to compare apps: try the task you'll repeat most often. How many steps does it take? Can you add a forgotten event? Can you correct a time without deleting the whole record?
Then check what the report contains. A simple frequency counter may suit one purpose; a clinician may need drinks, measured output, urgency or leakage alongside timing. Ask which fields matter rather than recording everything indefinitely.
Check the report and the privacy terms
Before paying, find out whether exporting is included or charged separately. Look at how dates, units and nighttime entries appear. Check whether you can share a readable document in the way your clinic accepts.
These records contain personal health information. Read the app's current policy for account requirements, sharing, deletion and any optional microphone use. We haven't audited the apps' security, and a store privacy label isn't an independent audit. Choose with a clear understanding of what information you're entering and where it goes.
Where Happy Floor fits
Happy Floor provides guided pelvic floor exercise sessions, including Control's submaximal contractions with full release between efforts. It isn't a bladder diary or a bladder-training scheduler, so it isn't a leading recommendation for the logging task in this guide.
If pelvic floor exercise is part of your agreed plan and you'd like narration, our general app comparison covers that choice. Our guide to strong urges to pee explores a podcast conversation about urgency; it serves a different purpose from choosing a diary.
What to bring to the next conversation
Bring the record in the format your clinician has requested and note anything that made it difficult to complete. Missing entries are more useful to acknowledge than to fill with guesses presented as measurements.
If you don't know why you're going frequently or have new or concerning symptoms, speak with your GP or continence service. A diary can describe the pattern; it can't establish the cause. Avoid using an app's graph to invent your own fluid restriction or waiting targets.
