A look inside.
Big, calm screens. Two taps for the everyday, more detail when you want to understand.
Everything your tummy wants you to notice.
Made for slow days, bloated days and the days in between. Quick when you are in a hurry, detailed when you want to understand.
Time since your last poop
A big, calm counter, a week strip and a month calendar with little Bristol icons. Days without and warning colours stand out gently.
Made for constipation
Log "tried, nothing", water, fiber and laxatives. Tummi shows how long a laxative took to work and sends a soft reminder after a few days without.
Food and IBS diary
Meals with FODMAP groups and common suspects, plus bloating, cramps, gas, nausea, heartburn and tiredness. Period, medication and a daily check-in for sleep, stress and mood.
Private photos
Taken with Tummi's own camera and kept only inside the app, never in your Photos library. Locked with Face ID. Tummi suggests a colour right on your iPhone.
Insights and patterns after meals
Comfort trend, Bristol mix, timing and longest gap. Tummi compares meals with how you felt 12 to 48 hours later, and honestly says so when there is too little data yet.
A report for your doctor
A clear PDF with your Bristol mix, frequency, symptoms and notes. Much easier than trying to remember the last six weeks in a short appointment.
For you and the ones you care for
Separate profiles for a child, a parent or someone you look after, each with their own diary.

Questions, gently answered.
Is Tummi a medical device?
No. Tummi is a diary, not a medical device. It does not diagnose, treat or prevent any condition. It helps you notice patterns and talk to your doctor with real notes instead of guesses. If you see blood, black stools, very pale stools, or have strong pain, fever or sudden changes, please see a doctor.
Where is my data stored?
On your iPhone. Tummi has no account and no server for your diary. It keeps daily snapshots on the device and an automatic backup in your own private iCloud, which only your Apple ID can access. If you turn on Apple Health, Tummi writes symptoms like constipation or bloating there.
What happens with my photos?
Photos are taken with Tummi's own camera and stored only inside the app. They never appear in the Photos app, your camera roll or iCloud Photos, and they are never uploaded. They are locked with Face ID. The colour suggestion is calculated on your iPhone.
Can I export my data?
Yes, for free. Export your diary as CSV for a spreadsheet, or create a full backup file and restore it later or on a new phone. With Plus you can also create a PDF report for your doctor and import entries from PCal, Happy Poop or Bowelle.
What does Tummi Plus cost?
Tummi Plus is available as a monthly subscription with a 7-day free trial, or as a one-time lifetime purchase. You see the exact price for your country in the app before you buy. Logging, calendar, photos, history and export stay free.
Can I track my child or someone I care for?
Yes. With Plus you can add several profiles, each with its own diary, so a parent or carer can keep notes for someone else.
Does Tummi use the Bristol stool chart?
Yes. Every entry starts with one of the seven Bristol stool types, the scale doctors use. The doctor report shows your Bristol mix over 14, 30 or 90 days.
Be kind to your tummy.
A tool, not a treatment. But a really good diary.
