Draw it with your feet

One path.
Two directions.
Endless little worlds.

Saki remembers the shape and height of your movement, then rebuilds it as a bright trail in the space around you.

When a round ends, reverse the route and begin the next one exactly where you are—no walk back to the old starting point.

01

Record

Make the route yours.

Walk a straight line, sweep around a corner, climb a gentle slope, or trace a playful course through an open space.
02

Project

Watch the world light up.

A glowing ribbon, fireflies, and animated collectables settle into the route you just created.
03

Play

Find the Perfect Line.

Stay centred for rainbow colour. Drift away and sound, haptics, and visual warnings guide you home.

The world is the course

Five ways a walk can surprise you.

Saki 2.0

More stable.
More expressive.
More yours.

Longer routes, smoother recovery, clearer feedback, and sharing tools make it easier to build a course—and easier to keep the moment.

Perfect Line

Precision has its own colour.

Walk the centre and the path transforms into a rainbow while fireflies celebrate around you.

Terrain aware

Smooth slopes. Honest steps.

The ribbon follows gradual height changes and keeps a little step-like character when the real world does.

Reverse round

The finish is your next start.

Complete a route, flip its direction and play it back without returning to the original beginning.

Capture + share

Keep the view you want.

Take a photo or record a run, preview it full screen, then choose Game Info or Clean AR before saving or sharing.

The camera is for the game

Your world
stays with you.

Saki has no account, advertising, or analytics. Camera frames, AR positioning, route data, and preferences stay on your device. Nothing is uploaded by Saki.

Designed for recovery

Tracking can recover after brief obstruction or a change in direction without discarding your whole route.

Why Sakura?

A small Christmas gift, made to glow.

Saki began as a present for a friend named Sakura. The flower at the end of the rainbow path is more than a motif—it is the reason this little world exists.
