Fluid Frontier

Drag through the dark, and
the colour follows your hand.

A living fluid canvas for your phone. Touch it and colour flows, curls, and settles like real ink and smoke. Leave it, and it keeps breathing on its own.

Frontier · graceful teal ribbons. Drag the water, or tap a colour to change it.

Eight moods, each its own physics

Not recolours. Each mood is a different force field and flow, from graceful ribbons to a great spiral that pulls everything in.

Make it yours

Words & emoji

Write into the water

Type a word or an emoji and watch it bloom in your colours, then the current carries it away.

Photos

Painted in water

Pour in a photo and stir. Every swirl paints a little more of it into view. Your photos never leave your phone.

Tune

Every slider yours

Drift, glow, swirl, fade, and more. Shape the water until it feels like yours, then keep the look.

Sound mode

Moves to your music

Turn it on and the water moves with the beat. It listens live and never records a thing.

Play

Two quiet games

Pop the bubbles, run the ember. The water itself is the controller.

Gift it

Send your water

Send a design to a friend with one tap. A friend without the app gets a little file that plays in any browser.
