These two apps are not really competitors — they answer different questions. Bladder Journal is a comprehensive bladder diary: unlimited free tracking of voids, volumes, fluid intake, urgency and leakage, with 10 chart types, an Apple Watch companion, Apple Health sync, urine color tracking and free PDF/CSV export for your clinician. BladderBoss, from Amara Therapeutics, is an eight-week guided program for women with overactive bladder, combining cognitive behavioral therapy, bladder training and pelvic health pilates, with a progress diary built in; it costs $24.99 per month after a 7-day trial and is available in the US and Canada. If you need to measure and document what your bladder is doing — especially if a clinician asked for a diary — Bladder Journal is the tool for that, and it is free. If you want a structured behavioral treatment course and fit its intended audience, BladderBoss is offering something a diary app does not. Using both is a perfectly reasonable option.

Which One Do You Actually Need?
Choose Bladder Journal if you:
- ✓ Were asked by a clinician to keep a bladder or voiding diary
- ✓ Want to measure and document rather than follow a course
- ✓ Need a PDF report to bring to an appointment
- ✓ Are tracking something other than OAB — nocturia, incontinence, retention, IC, prostate symptoms, pregnancy
- ✓ Are a man, or otherwise outside BladderBoss’s intended audience
- ✓ Live outside the US and Canada, or want a language other than English
- ✓ Want an Apple Watch app for discreet logging
- ✓ Do not want a recurring subscription for core tracking
Choose BladderBoss if you:
- ✓ Are a woman with overactive bladder, its intended audience
- ✓ Want a structured program to follow rather than a tool to use
- ✓ Are specifically looking for CBT-based behavioral techniques
- ✓ Want guided pelvic floor and pilates audio sessions
- ✓ Use Android, which Bladder Journal does not support
- ✓ Are comfortable with a $24.99 monthly subscription
Or use both
These are complementary rather than mutually exclusive. A behavioral program supplies technique and structure; an independent diary supplies the objective numbers that show whether it is working. Since Bladder Journal’s tracking is free, running it alongside a program costs nothing and gives you a before-and-after record that survives after the eight weeks end.
A Note on Bladder Training
Bladder training — gradually extending the interval between voids — is the behavioral technique at the center of most overactive bladder programs, and it is measured entirely through diary data. The interval you are extending, and whether it is actually extending, only exist as numbers in a voiding record.
If you want to understand the technique before paying for a program built around it, our guide to bladder training techniques covers the method, and how to interpret a bladder diary covers how to measure whether it is working.
Frequently Asked Questions
What is the difference between Bladder Journal and BladderBoss?
They are different categories of product. Bladder Journal is a bladder diary and tracking app: you log urination, volumes, fluid intake, urgency and leakage, and it charts the patterns and exports reports for your clinician. BladderBoss is a structured eight-week treatment program for women with overactive bladder, built around cognitive behavioral therapy, bladder training and pelvic health pilates, with a diary included as one component of the program. One is a measurement tool; the other is a guided course of treatment.
How much does each app cost?
Bladder Journal is free to download and all core tracking is free with no limits and no ads, including unlimited logging, charts, Apple Watch, HealthKit sync and PDF/CSV export. Optional AI features start at $2.99 per week or $5.99 per month. BladderBoss offers a 7-day free trial followed by an auto-renewing subscription of $24.99 per month, and the program content is the product rather than an add-on.
Which app should I use if my doctor asked me to keep a bladder diary?
For a diary specifically requested by a clinician, Bladder Journal is the better fit. It records everything a standard three-day voiding diary requires — timed voids, measured volumes, fluid intake, urgency and leakage episodes — calculates the 24-hour totals, average and maximum voided volumes and night-time share automatically, and exports a PDF you can hand over at the appointment. That diary function is free and unlimited.
Is BladderBoss available outside the United States?
BladderBoss is published by Amara Therapeutics and, according to its own materials, is currently available in the United States and Canada. Bladder Journal is available on the App Store worldwide and is localized in nine languages, which matters if you are outside North America or prefer a language other than English.
Can I use both together?
Yes, and for some people that is the sensible answer. A treatment program and an independent tracking record are complementary rather than competing: the program supplies the behavioral techniques and structure, while a full diary gives you and your clinician the objective before-and-after numbers that show whether the program is working. Because Bladder Journal's tracking is free, running it alongside another program costs nothing.
