Poop Tracker App: How to Keep a Useful Poop Diary

A doctor will usually want to know how often you go, what your stool looks like, and how long it has been like that. A poop diary puts those answers in writing so you can share them. To make it easier to keep going, start with a short entry.

Paper, a notes app, or a poop tracker app

	Paper or printed chart	Phone notes	Tracker app
Making an entry	Quick if the sheet stays in the bathroom	Typing it out each time	Tapping preset fields
Same fields every time	If you stick to a set template	Easy to drift	Built in
Seeing a whole week	Flip pages and count	Scroll and count	Calendar or chart view, if available
Taking it to a visit	Hand over the sheets	Copy and paste	Export, if the app has one
Who can see it	Whoever finds the paper	Depends on your phone backup	Depends on the app’s policy

This is an illustrative comparison, not a test of specific apps, and real features depend on the template or app you use. Pick whichever one you’ll still be using on day ten, and if it’s an app, read what it stores and sends before your first entry. Our poop log privacy guide shows how to read the store labels.

What goes into one entry

Log it soon after you go. A simple entry can use these five fields:

1. Roughly what time it was.
2. The Bristol type. The Bristol Stool Scale runs from type 1, separate hard lumps, to type 7, entirely liquid. Pick the closest match.
3. Color, if it looks different from usual.
4. How it went: straining, urgency, pain, or a sense you didn’t finish.
5. Whether there was blood or mucus.

Add one line about the day: anything new or unusual you ate, roughly how much water you drank, any medicine or supplement, and things like travel, poor sleep, or your period.

Made-up example: 7:40 am, type 2, brown, strained, felt unfinished, no blood. Day note: flew home yesterday, about four glasses of water, skipped breakfast.

A blank template to copy

If you’d rather start on paper or in a notes app, copy these headings. Fill in the first five for each bowel movement and the day note once a day.

• Date and time:
• Bristol type (1-7):
• Color:
• Straining, urgency, pain, unfinished:
• Blood or mucus:
• Day note (food, water, medicines, sleep, travel):

For constipation, the NIDDK suggests tracking bowel movements and what your stool looks like for days or weeks before a visit. If your clinic gives you a form or a set number of days, use that instead. Fill in ordinary days too, so the bad ones have something to compare against. Missing a day doesn’t ruin the diary; start again with the next bowel movement.

A sample week, and how to read it

A made-up week for someone who thinks they might be constipated:

Day	Bowel movements	Bristol type	Note
Mon	1	4	Normal workday
Tue	0	-	Flight, little water
Wed	1	2	Strained
Thu	1	1	Strained, felt unfinished
Fri	1	3	Back to routine
Sat	2	4, 4
Sun	1	4

Read it for questions to ask, since it can’t give answers. Here, types 1 and 2 with straining come right after a travel day with little water. That is worth mentioning to a clinician, but one week can’t show whether the trip, the water, or something else was behind it. The NIDDK lists hard or lumpy stool, difficult or painful passage, and a feeling that not all stool has passed among the symptoms of constipation.

With loose stool the questions change. The NIDDK describes diarrhea as loose, watery stools three or more times a day, or more often than is normal for you. If loose stool seems to follow a certain food, look at whether that food also shows up on days when nothing happened.

Turning the diary into a one-page summary

The NIDDK diarrhea diagnosis page lists what a doctor may ask about, including how long symptoms have lasted, how often they happen, what stool looks like, eating and drinking habits, medicines, and recent international travel. A summary that answers those in order might cover:

• When the change started, and whether it came on suddenly or gradually
• Your usual pattern compared with now, with counts and Bristol types
• Any blood, mucus, or black stool
• Repeats you noticed, worded carefully: “type 6 twice after takeaway,” not “takeaway causes it”
• What you have tried, and the medicines and supplements you take

Bring the full log too, since an average can hide stool that switches between hard and loose.

When not to wait for more entries

The UK’s NHS advises seeing a GP for constipation with blood in your poo, weight loss you can’t explain, tummy pain, regular bloating, or a sudden change in bowel habits. It advises calling 111 now for bloody diarrhoea or bleeding from the bottom, being sick so often you can’t keep fluids down, or diarrhoea lasting more than seven days, and 999 or A&E for a sudden, severe tummy ache. For black or dark red poo, it advises an urgent GP appointment or NHS 111, and 999 or A&E if you are bleeding non-stop from your bottom or see a lot of blood or large clots. In the US, the NIDDK says adults should talk with a doctor right away about diarrhea lasting more than 2 days, a high fever, or six or more loose stools a day. Outside the UK, use your own doctor or local emergency number. This article is general information, not medical advice.

How bellySignal helps

In bellySignal, a bowel movement entry takes a Bristol type from 1 to 7, a color, and blood or mucus flags. Urine color on a 1 to 8 scale, water in cups or milliliters, and food or habit triggers such as coffee, alcohol, or poor sleep are logged in the same diary. The Trends screen shows your entries over time, and from Settings you can export a PDF of the last 90 days to take to an appointment. An optional daily reminder can prompt you to log. Get bellySignal on Google Play.

Bathroom records are sensitive, so check what any app stores and shares. In bellySignal, your diary is stored on your device and can be used without signing up. Optional login, health platform sync, and export are available. Selected health values, including stool type and symptoms, are also sent to PostHog, which is on by default. The analytics switch in settings controls PostHog only. Firebase Analytics receives usage events without those health values and remains active. Privacy policy.
