Every step carries you further into space.
AstroWalk turns your daily step count into distance across the solar system. Today's walk shortens the way to the next world.
WALK, AND THE JOURNEY MOVES
Connect to the Health app and simply walk as you normally do. Your journey travels outward from the Sun to Mercury, Venus, and Earth. At 8,000 steps a day you'll reach Mercury, your first destination, in about five days.
A ROUTE BUILT ON REAL DISTANCES
The distances between worlds follow the real scale of the solar system. Unlike a step counter where a number simply goes up, you can see how far you have actually come.
A COLLECTION OF THE WORLDS YOU REACH
Every world you reach is recorded in your collection — the Sun, planets, dwarf planets, and their distinctive moons. Each entry includes an overview and key facts.
WATCH YOUR JOURNEY FROM THE HOME SCREEN
Add the widget and you'll see your progress and today's steps at a glance, without opening the app.
ABOUT PREMIUM
The free journey takes you as far as Earth. Premium unlocks the full route from the Moon to Pluto — moons included — plus the complete collection, and removes ads.
