Check your poop.
One honest glance tells you two things — consistency and color. Pick what you saw and get a plain-English read-out of what it usually reflects. No signup, nothing stored, takes ten seconds.
How did it look?
What color was it?
Seeing red or truly black? That’s outside what a color chip can read. Both often trace to food or supplements — beets, iron, bismuth — but either one without an obvious food explanation is worth an unhurried conversation with a clinician.
Your read-out
One check is a snapshot — useful, but it can’t tell you whether today is your normal or a detour. Patterns are the story, and patterns need a record.
Why these two signals?
Consistency and color are the two things a glance can genuinely read, and both respond to ordinary inputs — water, fiber, how fast things moved through you. Consistency is what the seven-type Bristol stool scale describes: types 1–2 generally mean things moved slowly, 3–4 sit in the comfortable middle, and 5–7 mean progressively faster transit. Color mostly reflects bile pigments doing their normal work, shaded by diet — which is why the boring answer, some shade of brown, is also the good answer.
What a snapshot can’t tell you
Whether today is typical for you. A Type 5 after a spicy weekend means something different than a Type 5 every day for a month, and no single check can tell those apart. That’s the whole argument for tracking: a few weeks of records turn one-off readings into a baseline, and genuine changes stand out on their own.
The automatic version
This page is the manual version of what Stoolio does from a single phone scan: it reads Bristol type and color the same way every time, adds hydration, fiber and fat-absorption indicators scored out of 100 plus an estimated transit range, and rolls each scan into one Stoolio Score — so the pattern builds itself, no discipline required.
Poop Check FAQ
What do the Bristol stool types mean?
The Bristol stool scale is the standard seven-type way of describing stool consistency, from Type 1 (separate hard lumps) to Type 7 (entirely liquid). Types 1–2 usually reflect slower transit, types 3–4 are the comfortable middle of the range, and types 5–7 reflect progressively faster transit. Consistency responds to everyday inputs like fluid, fiber and routine, which is why it’s the single most informative thing to notice.
What does stool color mean?
Most healthy stool lands somewhere in the brown family, because color mainly reflects bile pigments processed during digestion, shaded by what you ate. Green often traces to fast transit or leafy greens and food dyes. Pale stool can follow fatty meals or some antacids, and very dark stool often traces to iron supplements or dark foods — either one, if it hangs around with no food explanation, is worth mentioning to a clinician calmly.
Is one poop check enough?
One check is a snapshot; the useful information is in the pattern. A single unusual reading is usually explained by yesterday — a meal, travel, stress — while a change that persists across weeks against your own baseline is the thing worth noticing. That’s why clinicians recommend stool diaries, and why scanning apps exist: they make the record automatic.
Is this medical advice?
No. Poop Check is educational: it explains what consistency and color commonly reflect, and it doesn’t diagnose anything. Health concerns belong with a healthcare professional — and those conversations go better when you arrive knowing your own patterns.
