About PeeLog: Bladder Diary Tracker
Told to keep a bladder diary before your urology appointment? PeeLog gets it done — nothing else to learn. PeeLog is a simple voiding diary. Unlike big health apps, it does one job: log every bathroom trip in one tap and turn your records into a report your doctor can actually use. WHO IT'S FOR - You were asked to bring a bladder diary to a urology visit - You wake up at night to pee and want to know how often - You deal with urgency, leaks, or constant trips to the bathroom - Paper diaries feel like homework - You're keeping records for a parent or partner LOG IN ONE TAP - Urination: the time is filled in automatically. Enter the amount in ml, or just pick Small / Normal / Large — no measuring cup needed - Mark urgency and leaks, and add a short note - Fluids: amount and type (water, tea, coffee, alcohol) - Tap Bedtime at night and Wake up in the morning — nighttime voids are counted automatically - Forgot to tap Bedtime? Add or fix it later with any time you choose AUTOMATIC SUMMARIES - Today's count, total volume, and nighttime count at a glance - Weekly chart comparing daytime and nighttime frequency - Nocturnal polyuria index calculated for you - Day-by-day history for the last 14 days A PDF YOUR DOCTOR CAN READ - One day per page, in the same table format as the paper diaries used in clinics - Choose the last 3 days, the last 7 days, or any range up to 31 days - Share by AirDrop, email, or print - Preview the full report with a SAMPLE watermark before you buy anything SIMPLE PRICING - Recording, history, and charts are completely free - A single one-time purchase unlocks watermark-free PDF export - No subscription. No ads. PRIVATE BY DESIGN - All records stay on your device - No account, no server, no tracking PeeLog helps you keep records. It does not diagnose or treat any condition — please talk to your doctor about your symptoms.
