PUP
Yes, there are apps for that — and they’re more useful than you might think.
Why track your poop?
Most people have never tracked their bowel movements. You go, you flush, you move on. But your gut health is one of the strongest indicators of overall wellbeing, and patterns only emerge when you collect data over time.
Tracking helps you:
- Establish a baseline — know what’s normal for you
- Spot changes early — a shift in Bristol type, frequency, or consistency can be an early warning
- Connect diet to outcomes — see how food choices show up in your gut
- Talk to doctors with data — “I’ve had Type 6 stool for 3 weeks” is more useful than “my stomach’s been weird”
- Manage chronic conditions — IBS, Crohn’s, and other gut conditions benefit enormously from consistent tracking
What makes a good poop tracker?
Not all trackers are equal. Here’s what matters:
Speed
If it takes more than 30 seconds to log, you’ll stop doing it after a week. The best trackers let you log in under 10 seconds.
Bristol Stool Scale
The clinical standard for classifying stool. If an app uses its own made-up types, your data won’t be useful to a doctor.
Offline support
You won’t always have signal. The app should work offline and sync later.
Privacy
You’re logging personal health data. The app should have a clear privacy policy, no ads, and no third-party tracking.
Visualizations
Raw logs are hard to read. Good trackers show patterns through calendars, charts, and summaries.
Recommended: PUP
PUP is a free Android app built for exactly this. Every log takes about 7 seconds — pick your Bristol type, duration, and toilet type. It uses gamification (streaks, ranks, achievements) to keep you logging, and shows patterns through a monthly calendar, distribution charts, and a Poop Score.
No account required to start. Works offline. No ads.
Other options
- Bowelle — good for IBS tracking with food and symptom diaries
- Poop Tracker — simple, no-frills Bristol scale logging
- Cara Care — designed for digestive health with professional guidance
Getting started
Download a tracker. Log for 2 weeks without changing your habits. Look at the data. You’ll probably learn something about your gut that you didn’t know.
That’s it. No complicated setup, no sensors, no wearables. Just you, a bathroom, and an app.
