The 2026 “poopmaxxing” wave put smart toilets in the headlines: cameras that sit in your bowl, photograph each visit, and score it on the Bristol Stool Scale. The Kohler Dekoda reportedly lands around $599 plus a monthly subscription; the Throne around $319. They’re clever bits of engineering. But before you spend that, it’s worth asking what you’re actually paying for — because the thing that makes them useful isn’t the camera.
What the cameras actually do
Under the hood, they do three things: they remind you to pay attention, they classify what they see against the Bristol Stool Scale (a 1–7 chart doctors already use), and they keep a history so you can spot changes. All three are genuinely useful. None of them require a $599 device in your bathroom.
Honest comparison
| Kohler Dekoda | Throne | Gut Trainer (free app) | |
|---|---|---|---|
| Up-front cost | ~$599 | ~$319 | $0 |

| Bristol Stool Scale | Auto | Auto | One-tap log |

| A camera pointed at your body | Yes | Yes | No |
| Works anywhere (travel, other bathrooms) | No | No | Yes — it’s on your phone |
The part nobody selling a camera will tell you
The signal that matters for most people isn’t a high-resolution photo — it’s knowing your own normal. Once you’ve noted your pattern for a week or two, you can tell at a glance when something’s off, and that’s the thing worth acting on. A tap-to-log app captures exactly that, travels with you, and costs nothing.
Tracking for reassurance, not obsession. Nearly every expert quoted in the poopmaxxing coverage says the same thing: the goal isn’t chasing a “perfect” gut or scoring yourself daily. It’s noticing your baseline so you can stop worrying — and catch real changes early. Gut Trainer is built for the calm version of this: know your normal, feel settled, get on with your day.
How to get the same benefit for free
- Use the free Bristol Stool Scale. It’s the same 1–7 chart the expensive gadgets rate you against — no device required.
- Log it in a tap. Gut Trainer turns each visit into a one-tap entry, so a week of data takes seconds a day.
- Watch the trend, not the day. The calendar and trends view shows your pattern — that’s where the useful signal lives.
- Notice changes, then talk to a doctor. An app (or a camera) isn’t a diagnosis. If something changes and stays changed, that’s the cue to see a professional — no gadget replaces that.
Questions people ask
Is a $599 poop camera worth it?
For most people, no. What makes it useful — reminders, Bristol Stool Scale classification, and a history you can review — is available free in a phone app. The camera mainly automates the “looking” step, which you can do yourself in a second. If you have a specific medical reason and a clinician recommends one, that’s different; for general reassurance it’s hard to justify the price plus a subscription.
Is there a free alternative to the Kohler Dekoda or Throne?
Yes. A free Bristol Stool Scale tracking app like Gut Trainer does the useful 90%: one-tap logging, calendar history, trends, and gentle reminders — with no hardware, no camera in your bathroom, and no subscription. It also works anywhere, since it’s on your phone.
What is the Bristol Stool Scale, and do I need a device to use it?
The Bristol Stool Scale is a free 1–7 chart that classifies stool from hard lumps (type 1) to liquid (type 7); doctors use it to talk about bowel health. You don’t need any device — you can match what you see to the chart yourself, and an app lets you log and track it over time.
Isn’t tracking my poop every day a bit obsessive?
It can be, if you turn it into a daily score to “optimise”. The healthier use — and the one experts actually recommend — is learning your normal baseline so you feel reassured day to day and can spot genuine changes early. Gut Trainer is designed for that calmer approach, not for perfection-chasing.
Can an app or camera diagnose a gut problem?
No. Neither a $599 camera nor a free app is a medical diagnosis. They help you notice patterns and changes. If something changes and stays changed, see a doctor — that’s the one step no gadget replaces.
