How it works

From symptom to insight in three steps

1

Log it

Rate your stool and tag what was going on โ€” meals, mood, stress, sleep.

2

Spot the pattern

Gut Log watches for repeated links between your habits and how you feel.

3

Take action

Adjust what you can, and bring a shareable report to your next appointment.

Your gut, your business

Deeply personal data deserves real privacy

Gut health is sensitive. That's why Gut Log is built to keep your logs yours โ€” encrypted, never sold, and never harvested for ads.
