## What is UNKO LAB?

UNKO LAB is a bowel-movement diary you keep together with the Poop Professor. Log shape, colour, amount and any symptoms in a few taps, then watch your own rhythm on a monthly calendar and in a weekly review.

■ Logging in a few taps
Pick the shape from the seven Bristol types, then add only what matters: colour, amount, blood, abdominal pain, straining, incomplete evacuation, time spent and more. A day with no entry is treated automatically as a day without a movement — nothing to enter.

■ The Professor reads your log
The Professor puts patterns into words: leaning hard or loose, incomplete evacuation, time on the toilet, time of day, the link with coffee or exercise, how much of the month you have observed — 18 rules in all. Every reading links to the research or public-health source behind it. When the evidence is thin, the Professor says nothing. When a pattern runs long, the reading suggests seeing a clinician.

■ The Squishy Poop Tower
Entries stack up into a tower measured on a real-height scale: Tokyo Tower, Everest, and beyond. Crossing a landmark brings a celebration and a piece of trivia about the next one. Landmarks you have passed line up in your collection.

■ Research library
Original papers, reviews and public-health guidance, each summarised with its key points and its limits. Sources cited by a reading open straight from the card.

■ Your data stays on your device
No account. Nothing is sent to a server; your log lives only on your iPhone.

■ UNKO LAB Pro (one-time purchase, no renewal)
• No ads
• Tower grows 10× faster
• Full-detail CSV export
• The complete research library
Logging, the monthly calendar, the Professor's readings with their sources and consultation guidance stay free.

■ Fourteen languages
Japanese, English, Spanish, French, German, Portuguese (Brazil), Simplified and Traditional Chinese, Korean, Italian, Russian, Turkish, Vietnamese and Thai.

UNKO LAB is for observation and learning. It does not diagnose, treat or advise on medication. If you notice blood or black stools, diarrhoea with fever, severe abdominal pain or weight loss, please see a healthcare professional.
