Every step grows a world.
Tiny Worlds turns your daily walk into a living diorama. Walk to grow lush little worlds, keep the ones you finish, and build a quiet collection — no streaks, no guilt, just steps.

Walk. Grow. Keep.
No mini-games, no busywork. Just the walk you were already taking, turned into something that grows.
Your steps are the fuel
Tiny Worlds reads your steps from Apple Health. Every one counts toward the world you're growing — nothing else needed.
Meet the goal, climb a stage
Reach your daily step goal and your world advances through six hand-painted stages — from bare seed to a thriving biome.
Finished worlds become keepsakes
Complete a world and it settles into your collection forever. No two are ever quite the same.
Plant a seed, discover a world
Three everyday biomes to start, and an exotic trio for World Keepers. Each seed grows into something you haven't seen yet — and no two you collect are ever the same.






A calm companion, not a taskmaster
No streaks, no guilt
Miss a day and nothing withers. Your worlds wait patiently for you. Tiny Worlds is a gentle nudge, never a source of pressure.
A collection that's yours
Every completed world is a keepsake — pinch to zoom, grouped by biome. A little museum that quietly fills up as you move through your days.
