Currently, Bladder Journal is available exclusively for iOS (iPhone and Apple Watch). An Android version is not available at this time. If you're looking for cross-platform options, see our guide to the best bladder diary apps for a comparison of alternatives.

A bladder diary (also called a voiding diary or urination log) is a systematic record of your urinary habits — including when and how much you urinate, what you drink, urgency levels, and any leakage episodes. Healthcare providers often recommend keeping one for 3-7 days to diagnose conditions like overactive bladder (OAB), urinary incontinence, or frequent urination. Bladder Journal makes this process simple and digital.

Bladder Journal lets you track: urination events (time, urgency, stream strength, pain level, duration, volume), fluid intake (drink type and amount in ml/oz), leakage episodes (severity, pad changes, notes), and free-form notes for symptoms, dietary factors, or medication changes. All entries include automatic timestamps and support custom notes.

The Apple Watch companion app allows discreet tracking directly from your wrist. You can log urination events, start/stop the urination timer, record fluid intake, and note leakage incidents — all without needing your iPhone nearby. Data syncs automatically to the iPhone app.

Free charts include: Frequency (daily urination count), Urgency Levels, Time Gap Between Urinations, Stream Strength Trends, Fluid Intake vs Urination Correlation, and Leakage Events. PRO charts (with Deep Insights) add the Bubble Heatmap with Daily, Weekly, Monthly, and Yearly views for at-a-glance pattern recognition.

Yes, Bladder Journal offers free PDF and CSV exports with no subscription required. You can select a date range and choose between detailed or summary views. These reports are formatted for healthcare providers, making it easy to share accurate bladder diary data at your next doctor's appointment.

Yes, and it is free. Bladder Journal syncs water intake and bladder events with Apple Health in both directions, so entries from other apps show up too. It can also link your diary entries to Apple Health workouts, so you can see whether leaks or urgency follow exercise, and linked workouts appear in your PDF report. With PRO's AI features, it can read sleep data to put nighttime urination in context. You have full control over what data is shared.

Smart Alerts is a PRO feature (included with Yearly PRO) that uses AI to anticipate your bladder needs throughout the day. It learns from your unique tracking patterns to deliver personalized predictions — helping you plan activities with confidence, stay on top of hydration, and prepare for nighttime. Each alert includes a confidence score that improves over time as the system learns your rhythms.

Yes, Bladder Journal includes a urine color tracking feature with a 7-level hydration chart. Each level corresponds to a hydration status from well-hydrated (pale/clear) to severely dehydrated (dark amber). Tracking urine color alongside your other bladder data helps you monitor hydration patterns and spot potential dehydration before it affects your bladder health.

Audio Analysis is a PRO feature that estimates urine volume using sound analysis technology. When you start the urination timer, the app uses your device's microphone to analyze sound characteristics and estimate flow rate and total volume. All processing happens 100% on-device — no audio is ever stored or transmitted to servers.

Deep Insights is an AI-powered feature that analyzes your complete bladder tracking history to identify patterns, timing clusters, correlations between fluid intake and symptoms, and behavioral trends that basic charts can't reveal. It provides personalized summaries and includes the exclusive Bubble Heatmap chart. Deep Insights is included in every PRO plan.

AI Chat lets you ask natural-language questions about your bladder diary data. For example: 'How was my hydration yesterday?', 'Show me my caffeine patterns this week', or 'What are my peak urgency times?' AI Chat is included with Yearly PRO ($29.99/year) with a limit of 30 messages per day.

All PRO plans include Audio Analysis + Deep Insights: Weekly at $2.99/week, Monthly at $5.99/month, Quarterly at $14.99/3 months (save 17% vs monthly), or Annual at $29.99/year (save 58% vs monthly, also includes Smart Alerts and AI Chat). Core tracking features remain completely free.

Your diary is stored on your device by default, and optional iCloud sync uses your own private iCloud, which we cannot access. Audio Analysis runs entirely on your iPhone: no recordings are stored or sent. The optional PRO AI features (Deep Insights, Smart Alerts and AI Chat) send the diary data they need, encrypted, to our server and an AI service provider to produce their results; nothing is sent unless you use them, and requests carry no name, email address or account. We never sell your data or use your health data for advertising. Our privacy policy has the details.

No. All audio processing for Audio Analysis happens 100% on your device. No audio recordings are stored, saved, or transmitted to any server. This makes Bladder Journal's Audio Analysis more private than alternatives like Bladderly or proudP, which process audio in the cloud.

Yes, Bladder Journal supports Face ID and Touch ID app lock for additional privacy. You can enable this in the app's settings to prevent unauthorized access to your bladder diary data.

Yes, Bladder Journal is designed to help users manage OAB by tracking urination frequency, urgency levels, fluid intake, and leakage episodes. This data helps identify triggers and patterns crucial for bladder training programs. Many urologists recommend keeping a detailed bladder diary as the first step in OAB management. See our guide to overactive bladder management for more information.

Yes, Bladder Journal is excellent for tracking nocturia. It logs nighttime urination trips with timestamps, tracks evening fluid intake timing, and when paired with Apple Watch sleep data, can correlate nighttime bathroom visits with sleep patterns. This data helps your healthcare provider understand your nighttime voiding patterns and recommend appropriate treatment.

Yes, Bladder Journal supports bladder training programs by tracking voiding intervals, urgency levels, and progress over time. The Time Gap chart shows your intervals between urinations, and Deep Insights can identify whether your intervals are improving. Learn more about bladder training techniques in our detailed guide.

Absolutely. Bladder Journal generates professional PDF and CSV reports that are formatted for healthcare providers. You can select a date range, choose detailed or summary views, and share reports via email, AirDrop, or print. Having a digital bladder diary with accurate timestamps and visualizations makes your appointments more productive.

No. Bladder Journal is a tracking and visualization tool — not a medical device. It does not diagnose conditions or provide medical recommendations. AI-generated content (Deep Insights, AI Chat) is for informational purposes only. Always consult a qualified healthcare provider for medical concerns.
