The poop tracker you'll actually enjoy opening.
Log in a few seconds, keep a streak going, and bring something to listen to. No account. No cloud. Your logs never leave your phone.
A little diary for the smallest room
Plunk keeps a simple record of what you log, shows your own patterns as plain counts, and keeps you company while you sit.
Log in three taps
Tap Quick Log, pick one of the seven Bristol types, done. Add details if you like, save a preset, or log in one tap from a widget or the Quick Settings tile.
Sessions with sound
Start a session, pick a soundscape like Rainy Stall or Brown Noise Blanket, and read the day's cards or solve a pipes puzzle while you sit.
History and stats
A calendar and list of every log, weekly and monthly stats, and pattern notes like "You logged coffee on 5 of your 5 urgent days."
Streaks and badges
Keep a streak, level up, earn badges and monthly stamps, and dress up the mascot from the wardrobe.
Discreet by default
Widgets and reminders say things like "Daily check-in", never what the app is for. App Lock keeps it behind your fingerprint, face or screen lock.
Never lose a log
Turn on automatic backup and Plunk saves an encrypted copy to a folder you choose, every day or week. Export to CSV or share a PDF summary any time.
Throne Passport
Name the places you've been, like "Grandma's" or "Tokyo", and collect them as stamps. Just words you type: Plunk never asks for your location.
Show off, safely
Share a card when you hit a streak, earn a badge or level up. Cards never include what you logged.
Six languages
English, Español, Português (Brasil), Deutsch, Français and 日本語, each with its own jokes and riddles to read while you sit.

- No analytics · no tracking tools
- Ads only when you ask · never with your logs

A diary, not a doctor
Plunk describes what you logged and never what it means. It isn't a medical device and doesn't give medical advice. If something feels off, it's always okay to check in with a doctor.
