Can you read this image?

A real satellite view of Agra, taken by Sentinel-2 on 6 March 2026. The Yamuna bends past the Taj Mahal. Answer the way you would in the app: every answer tells you why.

Why do the fields across the river glow bright red?

How it works

Learn. Earn belts. Keep it going.

A question in the app, with why the right answer is right and why the picked one is wrong

Learn in five minutes

Three new terms a lesson, each with a diagram, and a reason after every answer.

The belt ceremony after passing the Foundations white belt exam

Earn belts by exam

Lessons are training. A belt means passing a timed exam, no hints, 80% to pass.

The training path with a 6-day streak and today's goal met

Keep it going

A daily streak and a gentle reminder. Terms come back just before you'd forget them.

What you'll learn

Twelve disciplines. White to black belt in each.

Start with the Foundations, then go deep where you need to. Each discipline has its own eight belts.

FAQ

Questions

Do I need to know GIS already?

No. The Foundations start from what GIS is and what a pixel is. Already use GIS? A short check lets you skip them.

How do belts work?

You don't get a belt for finishing lessons. Train a belt's units, then sit its exam: about 25 questions in 15 minutes, no hints, 80% to pass. Each discipline has its own belts, and your dojo rank counts them all.

Is it free?

The course is free to learn. A paid Pro plan will come later with extras, like an AI tutor and challenges with real data. Cancelling will be as easy as subscribing.

When and where can I use it?

We're building it now: Android and the web first, iPhone after. Join the waitlist for one email when it opens.

Who writes the content?

Every lesson is written in our own words, checked against open sources, and reviewed by a working GIS analyst before it ships.
