PeePal
Free browser diary · UK
A free bladder diary. How often, and how much — five days of your own record.
Write down your drinks and visits for five ordinary days, and you have the kind of record often asked for before an appointment — instead of an estimate you gave under pressure.

No verdict attached
PeePal does the arithmetic and stops. No score, no interpretation.
“I logged for 4 weeks and it did materially change my life; now I can finally sleep through the night.”
Before you start
It takes five days and a few seconds an entry. Worth knowing first.
- An entry is a time and an amount in millilitres. A visit can also record leakage, and how urgent it felt.
- The diary keeps the last five days. Anything older is deleted from this browser, not hidden from you.
- It stays in this browser. Clearing your browsing data clears the diary with it.
- There is nothing to fill in before your first entry. No profile, no questions.
What you hand over: a frequency volume chart
The diary produces plain text laid out like a frequency-volume chart, which is the shape a clinic already reads. You can copy it into an email, or print it. This is a whole complete five days, not an extract.

Urgency is recorded as normal, strong or could not wait, as the person chose it. A visit whose urgency was never recorded is printed as "not recorded". 2026-09-06 Sunday 07:40 drink tea 250 ml 08:05 visit 220 ml leakage no urgency normal 13:30 visit leakage no urgency normal 19:00 drink water 300 ml total in 550 ml, total out 220 ml, 2 visits, 0 at night, 0 leaks 2026-09-07 Monday 08:00 drink coffee 250 ml 08:30 visit 240 ml leakage no urgency normal 23:40 visit night 150 ml leakage no urgency strong total in 250 ml, total out 390 ml, 2 visits, 1 at night, 0 leaks 2026-09-08 Tuesday 07:30 drink tea 250 ml 07:45 visit 200 ml leakage no urgency normal 10:15 drink water 300 ml 11:20 visit leakage no urgency strong total in 550 ml, total out 200 ml, 2 visits, 0 at night, 0 leaks 2026-09-09 Wednesday 02:10 visit night 180 ml leakage yes urgency could not wait 08:15 drink tea 250 ml 12:00 visit 210 ml leakage no urgency normal total in 250 ml, total out 390 ml, 2 visits, 1 at night, 1 leak 2026-09-10 Thursday 08:00 drink coffee 250 ml 08:40 visit 230 ml leakage no urgency normal 16:20 visit leakage no urgency normal total in 250 ml, total out 230 ml, 2 visits, 0 at night, 0 leaks
On day five
Once a fifth day has entries, the diary shows what your own five days add up to — counts and totals drawn from your entries, with no score and no interpretation — and offers the text above.
That is the end of what the browser diary does. PeePal for iOS keeps the same five-day diary on your iPhone. Explore PeePal for iOS.
The app keeps your preferences — like whether the visit form offers a period option — on the device. It stores no identity facts: not an account, not a name, not biological sex.
This version of the app sends no usage counts. Our App Store privacy details list product analytics because a later version may ask your permission to send weekly usage counts. The browser diary on this site runs no analytics at all.
A record, not a diagnosis
PeePal writes down what you tell it and does the arithmetic. It does not judge the result, and it does not tell you what it means.
