[Make your memories cinematic] Organize & relive home videos Series, tags, autoplay

Turn your everyday stairs into a small adventure.

Dandan is an app that lets you explore famous landmarks around the world, based on how high you climb the stairs.

Every time you take the stairs, you travel a little further with a cute character by your side, slowly discovering the world step by step.

【What kind of app is this?】

In Dandan, the number of steps and the height you climb directly become your progress.

• How far did you climb today? • Which country’s landmark will you see next? • Just a little more to earn a new badge!

With these small moments of excitement, you can naturally turn stair climbing into a daily habit.

Even if you’re not great at exercise, Dandan is designed to make you think, “I’ll take the stairs for now.”

As you climb higher, famous landmarks from around the world appear.
