Your clinic asked you to keep a bladder diary for three days. This is that diary, on your phone, and it prints the form they asked for. WHAT IT RECORDS Every time you pass urine, with the amount from your jug, or a tick when there was no jug to hand. How urgent it was, on the 0 to 4 scale your own form uses. Every drink, with the amount and what it was. Leaks, with what you were doing when it happened. Pad changes, weighed if you have been asked to weigh them. When you went to bed and when you got up, which is the only way the times you were up in the night can be counted. FOUR FORMS, ONE RECORDING - The three-day bladder diary NHS trusts and continence services publish: hourly rows, millilitres, a 0 to 4 score, leaks with a reason, pads. - The daily bladder diary published by the National Institute of Diabetes and Digestive and Kidney Diseases, and the version the Urology Care Foundation prints: hourly bands, trips counted, small, medium or large. - A frequency volume chart: the times and the volumes, and nothing else. - A plain list with the exact times. Pick the one you were handed. Change your mind later and it reprints on another, with nothing you recorded altered. Millilitres or fluid ounces. A4 or US Letter. MADE FOR TWO IN THE MORNING Four buttons pinned to the bottom of the screen, so they can never be scrolled past. The amount box is already open and waiting when you tap "I went". The urgency score is optional. A diary day runs from six in the morning, the way the printed forms do, so a void at three in the morning lands on the sheet for the day before instead of starting a new one. TWO DIFFERENT 0 TO 4 SCALES There are two in circulation on NHS diaries and they do not mean the same thing. One describes what happened, from passing urine with no urge at all to not reaching the toilet in time. The other describes how long you could have waited. The app asks which one you were given and prints its full wording at the foot of the sheet, so nobody has to guess what your 3 meant. WHAT IT WILL NOT DO It records what you write down and prints it. It does not score your symptoms, work anything out about them, compare you with anybody, or tell you what any of it means. Questionnaires like the OAB-q and the ICIQ produce numbers that belong to the clinician who asked for them. This is a diary. Reading it is not its job. NOTHING LEAVES YOUR PHONE No account, no sign-in, no server of ours anywhere. The app works in aeroplane mode. The only copies that exist are the ones you make: a sheet you print, a PDF you send, a backup file you keep. Lock it with Face ID if you want it locked. FREE, AND WHAT THE UNLOCK ADDS Recording is free and unlimited, forever. Every void, drink, leak and pad, on as many days as you like. The free version prints the first two pages of the chart, which is enough to see exactly what the finished thing looks like. One purchase, no subscription, Family Sharing included, adds: - Every page of the chart, with the totals and the scale it used - The whole diary as one file to send: the chart and a spreadsheet of every entry - More than one diary, for the three days before treatment and the three days after - An encrypted backup file you hold yourself - A passphrase on the PDF you email A bladder diary is usually the first thing looked at in a urology, urogynaecology or continence appointment. Take the printed sheet with you, or send the PDF ahead. Your copy stays on the phone either way.
