PeeLog: Bladder Diary Tracker downloads
Worldwide, per day, and installs to date. The band is open; the exact number is free with an account.
How this is calculated
Apple publishes no download counts. App Store downloads come from chart positions and daily rating growth per country, calibrated on Google Play install counts; lifetime installs from ratings worldwide × installs per rating. Confidence is the chance the real number is within half to double ours.
Active users
All platforms, worldwide. Free with an account.
Stickiness (DAU / MAU)
how many monthly users open it on a given day
How this is calculated
Monthly users come from lifetime installs across every store, fitted on monthly active user figures companies publish; daily users = monthly × the typical daily/monthly ratio for the category. Confidence is the chance the real number is within half to double ours.

Review momentum
59/100
faster than 65% of Medical apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
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.

- You wake up at night to pee and want to know how often
- You deal with urgency, leaks, or constant trips to the bathroom

- 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

- Choose the last 3 days, the last 7 days, or any range up to 31 days
