Tanuki Tenki

Tanuki Tenki

A gentler forecast for your gut.

Tanuki Tenki swaps clinical stool charts for a simple weather scale. Log your day as sunny, cloudy, rainy, or stormy, and watch a hidden ink painting appear as you keep showing up.

Coming soon to the App Store. One email at launch, nothing else.

How it works

  1. Log today's forecast

    Skip the clinical stool chart. Pick the weather that matches your day: sunny, cloudy, rainy, or stormy. It takes seconds.

  2. 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.

  3. 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.

Questions

What is Tanuki Tenki?

A gut-health tracker that uses a simple weather scale instead of a clinical stool chart. As you log consistently, a hidden ink painting gradually appears.

Why weather instead of a stool chart?

'Tenki' is Japanese for weather. Calling your day sunny, rainy, or stormy is quicker and less clinical than a medical chart, and it still captures the same information.

How does the painting work?

Each log reveals a little more of a sumi-e ink painting. It starts as blank paper, fills in with ink linework, and gains color as your consistency builds. Missing a day never undoes your progress.

Who are the tanuki?

Tanuki are visitors who show up as you keep logging. Some appear only in certain weather, others after a streak or milestone. Each one you meet is saved to your album.

Is my data private?

Yes. Your logs are stored on your device by default and are never sold or shared.
