SunPo: Fictional World Walk
AI Generated GPS Adventure
Only for iPhone
Free · In‑App Purchases
iPhone
Every step you walk moves your journey through a fictional world.
Today the ocean floor, tomorrow the moon — 360° views and sound, carried by your own two feet.
Free, no sign-up. Download, and today's walk is all you need to begin.
Choose a world and start walking — your journey begins. As you follow your usual streets, the journey on screen moves with you. When you reach a sight, a 360° panorama opens; tilt your phone and the view shifts around you. Listen for the soundscape composed just for that scene. Start walking again, and the next sight draws closer — a small journey that lasts your whole walk.
■ 30 fictional worlds, 150 sights
The deep sea, outer space, the moon, a cherry blossom tunnel, Ryugu Palace, a thunder cathedral, the kaleidoscope corridor, a meadow of doors, lava fields, an autumn valley, sky islands, Neo Tokyo — 30 worlds, each with 5 sights. Choose the worlds you love and download just those.
■ Real distance, real progress
Your GPS-measured walking distance becomes distance traveled in the world. A loop around the park or the long way to the station — every bit of it brings the next sight closer.
■ A soundscape for every scene
Each of the 150 sights has its own ambience, layering natural sound with music. The deep sea sounds like the deep sea; the cherry blossom tunnel sounds like spring. Put in your earphones, stand at a sight, and let the view and the sound surround you.
■ Designed for safety first
While you walk, the screen shows only a map. The 360° view opens only while you are standing still — so you can stay aware of your surroundings and walk with peace of mind.
■ Your walks, on the record
Distance, steps, and calories are tracked automatically. Look back by month or all-time and see how far you have walked.
■ Free, no sign-up
Free to download, no account needed. Open the app and you are ready to walk.
Beyond your usual walking route, worlds you have never seen are waiting.
Pick today's destination and head out for a walk.
