Urine Log is a simple voiding diary (bladder diary) that makes it easy to log urination and bowel movements and review them in graphs, calendars and PDFs. The app uses S for urination (pee) and L for a bowel movement (poop). These short labels come from “small” and “large” bathroom visits; they identify the type of visit, not the amount. Keep a daily voiding diary to review changes, or show it at a medical appointment. ■ Easy logging • Tap S or L once to record the current time; add an optional note. • Review past entries and edit their times or notes in the log list. • Log without opening the app using a Home Screen widget. The small widget has your chosen button; the medium widget has both. • Log on Apple Watch and sync entries to iPhone. ■ Review each type separately • See daily counts in graphs and the calendar. • Check average, shortest and longest intervals for each type in hours and minutes (Based on the last 7 days. Intervals under 5 min are excluded). • Switch between “All”, “Urination only” and “Bowel movement only”. • See the total for the last seven days, including today. ■ Monthly reports and export • Separate counts, daily averages and average intervals for urination and bowel movements. • Daily graphs, hourly counts and comparison with the previous month. • Average daily nighttime urination count, from 8 p.m. to 6 a.m. • Doctor Visit Record (3 or 7 days): a voiding-diary-style PDF listing the time of each entry by day. The last 3 or 7 days, including today, are available to everyone. • Share a one-page A4 PDF, or export a date range as CSV for use on a computer. • Choose the new or previous format under Settings > Monthly Report > Format. The previous format retains combined counts and intervals and the clock-face time-of-day chart. ■ Free features and access Regular iPhone logging and the log list are free and unlimited. Home Screen widget logging requires no purchase. After the seven-day trial, analysis, monthly reports and CSV export are limited to the last seven days. A one-time Premium purchase or an active 30-Day Pass provides access to the full period. Apple Watch logging requires an active trial, Premium or an active 30-Day Pass. ■ Please note This app organizes records you enter for personal use. It does not diagnose, treat conditions or medically assess your records. Consult a healthcare professional about your health. “Nighttime” is a fixed period from 8 p.m. to 6 a.m.; the app does not automatically measure urination during sleep or awakenings to urinate. Records are stored on your device. Make daily logging an easy habit.

DONE. Tap Intake or Output, then choose an amount. That’s it. No required notes. No questionnaires. No long forms. Log from your iPhone, Home Screen widget, or Apple Watch.

Verdict
The clearest difference is update cadence: Urine Log at every 5 days against Bladder Diary's monthly. Bladder Diary's advantage is iOS requirement (18.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.
