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
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.
