Porcelain

Poop tracker for iPhone

You look. Porcelain notices.

Take a quick look and tap once. Porcelain works out your normal and lines up your days, so you can see what's usual for you and what's different. No ads, no account, your logs stay on your iPhone, and photos you take here stay out of your Photos app.

Coming soon to the App Store for iPhone.

Our photo promise

Photos you take here stay out of your Photos app.

A photo can help you remember a color or show a doctor what you saw. It shouldn't turn up when you're showing someone your vacation pictures.

  • Never in your camera roll. Photos you take with Porcelain's camera aren't added to your Photos library, so they don't appear in iCloud Photos or Memories.
  • Blur, your choice. Saved photos start blurred; touch and hold one, or tap Show photo, to see it. Prefer them clear? Turn off Blur saved photos in Settings. Either way, photos are hidden in the app switcher and during screen recording.
  • Only on your iPhone. No account, no upload. Lock Porcelain with Face ID if you like.
  • Always optional. Logging never needs a photo.

A photo you choose from your Photos app was already there, and stays where it was.

Why keep a poop log?

How often you go and what it looks like are different for everyone. Knowing what's normal for you makes a change easier to notice, and easier to bring up with a doctor if it keeps happening. What the seven shapes mean · How often is normal?

One tap, then get on with your day

Tap a shape and it's saved. Add color or a note only when you want to. A home screen widget logs without opening the app.

Know your normal

After 7 logged days, Porcelain shows how often you usually go and the shape you see most often. No scores, no judgments, no streaks to keep.

Days without a poop count too

Tap "No poop today" and that day is logged. Days you don't log stay blank, never counted as zero.

Fair and ad-free

Logging, your full history, backups and the doctor report are free. No ads. Plus is optional, and can be bought once — no subscription required.

The Japanese habit of kanben

In Japan, there's a word for taking a quick look at your poop before you flush: kanben (観便), "looking at your stool." Apps and health campaigns there encourage it as an everyday habit.

The idea is simple. How often you go and what it looks like are different for everyone. When you know what's usual for you, it's easier to notice when something changes, and to describe it clearly if you ever talk to a doctor. Porcelain is made by an independent developer in Japan who wanted to bring this small habit to the U.S., quietly and privately. Kanben is the look; Porcelain does the noticing. More about kanben.

Everything you need, nothing you don't

  • One-tap logging, in the app or from a home screen widget — and Porcelain opens from Control Center, the Action button, the Lock Screen or Siri
  • Your normal: how often you usually go, your most common shape and your usual gap, after 7 logged days
  • Porcelain notices: a card on Today when your own logs change for several days, like pale or looser poops in a row or fewer poops than usual in a week. Free, never a notification, and not a diagnosis
  • Bristol Stool Scale and color, plus amount, blood or mucus, pain, and urgency if you want them
  • Habits beside your logs: water, fiber, exercise, sleep, coffee, alcohol, stress — and up to 12 of your own
  • Tummy today: tap bloated, gassy or cramping on any day, with or without a poop
  • Apple Health, if you like: sleep, steps, periods, water and fiber, read only, with nothing to tap each day
  • Trends for the last 30 days, and a look back at last week
  • Private photos: kept inside the app, out of your Photos app, and blurred if you like
  • "No poop today" is a log of its own, so a day without one is recorded, not skipped
  • Backups you can see: automatic backups on your iPhone, and a backup file (with photos) you can save anywhere
  • A doctor report as a PDF, free, and CSV export of everything
  • Family: separate logs for a child or a parent on this iPhone — you and one family member are free
  • Face ID lock, and your logs are hidden in the app switcher
  • Large text and dark mode that follow your iPhone settings

Free to look. Plus notices more.

Free: logging, photos, habits, your normal, notices about changes in your pattern, the last 30 days of trends, your full history, backups, CSV export, the doctor report, one family member and Face ID lock. No ads.

Porcelain Plus answers the questions people ask: Your week, last week set beside your usual. Is it the coffee? Days with a habit, or the days after it, beside your other days (your first habit is free). Is it your period? Your poops beside your cycle from Apple Health. Did something new change anything? The days before and after (your first comparison is free). Does more fiber do anything for you? Two 28-day programs, with tips from the NIDDK and the CDC. Plus trends for 90 days, a year or any dates, "Your year", more family members and other app icons. $29.99 a year with a 1-month free trial, $4.99 a month, or $49.99 once.

Private by design

Your logs stay on your iPhone. They are never sent to our servers, and we can't see them. No account, no email, no tracking of your health data. Photos you take in Porcelain stay inside the app: they are not added to your camera roll or iCloud Photos. Your iPhone's own backup (iCloud Backup or your Mac) includes your logs and photos if you have it turned on, and you can save a backup file wherever you choose.

Questions

When will it be available?

Soon, on the App Store for iPhone. This page will link to it on launch day. We don't keep a mailing list.

Will there be an Android version?

iPhone comes first. If you need Android, email us — it helps us decide.

Why would I track my poop?

To know what's normal for you. How often you go and what it looks like vary from person to person. Once you know your normal, a change is easier to notice, and easier to mention to a doctor if it keeps happening.

Can it tell me what's wrong?

No. Porcelain is for keeping your own records. It isn't intended to diagnose or treat any condition. If something worries you, or you notice blood or black stools, talk to a healthcare professional.
