UNCHIKUN - Track your poops with friends

by

UNCHIKUN is a poop tracker that turns bathroom visits into a fun, social experience — think Duolingo, but for your gut health. Track poops with cute characters, share stories with "Poop Buddies," and level up as you log more. Features include Bristol stool scale, volume tracking, poop map, calendar history, and quests. Built solo with Claude Code, localized in 56 languages, on iOS and Android. Because everyone poops — why not make it fun?

Hey Product Hunt\! I'm Ryo, a solo indie developer from Japan. I built UNCHIKUN because I noticed something funny — everyone poops every day, but nobody talks about it. Gut health is one of the most important indicators of overall wellness, yet there was no app that made tracking it actually enjoyable. So I made a Duolingo-style poop tracker where you can log your poops, track Bristol stool scale and volume, earn levels, complete quests, and even share your poop stories with friends ("Poop Buddies"). The entire app was built with Claude Code as my AI coding partner. It's localized in 56 languages and available on both iOS and Android. I'd love to hear your feedback — and yes, I want to know about your poops too. Happy tracking\!

@busmark_w_nika Haha no photos required, I promise! You just tap to log and optionally select the shape (Bristol scale) and volume. Your dignity stays fully intact.

Nika

@tsuzuki817 Okay, please, keep it as it is :D

This is awesome Ryo! I am free user to check the status of health from recognizing the shape of poop and how many times pooped. It will be much better if it is incorporated with the scientific evidence of health status of the shape of poop and how many times people pooped a day. Creative application!

@jihwankim55 Thank you Jihwan! That's a great suggestion. I'm actually planning to add health insights based on Bristol stool

scale data and frequency patterns — like alerts when your gut health might need attention. Stay tuned, and thanks for using UNCHIKUN!

@tsuzuki817 Looking forward to it! Keep going Ryo!

Well if you could add friends in here, I think that's the ultimate friendship test!

@nayan_surya98 It already exists! You can add "Poop Buddies" with a friend code and see each other's poop stories. It really is the ultimate friendship test — if you can share your poop, you can share anything.

Love this idea, do the poop buddies actually motivate each other?

@paula_nwadiaro Absolutely! You can see your Poop Buddies' stories, react to them, and leave comments. You also get push notifications when they poop, so it's surprisingly motivating — nobody wants to be the only one who hasn't pooped today!
