A gentler forecast for your gut.
Coming soon to the App Store. One email at launch, nothing else.
How it works
Log today's forecast
Skip the clinical stool chart. Pick the weather that matches your day: sunny, cloudy, rainy, or stormy. It takes seconds.
Reveal the painting
Each day you log uncovers more of a hidden sumi-e ink painting, from blank paper to linework to full color. Miss a day and nothing is lost.
Collect tanuki visitors
Tanuki start to visit as you log. Some come in certain weather, others at milestones. Each one you meet joins your album.
Why it's different
Most gut-health apps borrow the language of clinics: stool charts, symptom logs, sterile color schemes. Tanuki Tenki tracks the same information as weather. A forecast, not a diagnosis.
The painting only moves forward. A missed day never erases progress, because the app rewards showing up, not getting “good” results.
The tanuki are visitors, not pets. There is nothing to feed or keep alive. They find you over time, and some are rarer than others.
