Fluid
Classic swirling ink. Currents braid, curl into vortices and slowly dissolve.
Fluid Art — liquid light on your screen
iOS · Android · Free with Pro unlock
A living pool of liquid light in your pocket. Paint with your fingers — or just watch it dream.
Thirteen kinds of physics
Same paint, different universe
Ripple
A still pond. Every stroke becomes rings that expand, reflect and interfere.
Oil
Glossy, viscous paint. It slides downhill when you tilt the phone and pools into glass-smooth puddles.
Fire
Heat instead of water. Paint ignites, rises on its own buoyancy and burns out into embers.
Orbit
A quiet gravity well in the center bends every current into slow, circling arcs.
Slime
Thick, deeply coloured goo that swells and settles on a slow cycle, lagging behind your finger like soft putty.
Pro
Coral
Reaction–diffusion growth: glowing branches creep, fork and fill the screen like living reef.
Pro
Marble
Paper-marbling swirls. Drag a comb through the surface and the colour bands bend with it.
Pro
Sand
Grains pour from your finger, pile into dunes and slump under shifting winds.
Pro
Watercolor
Wet pigment blooms and bleeds across paper, pooling at soft edges.
Pro
Kaleidoscope
Every stroke folds into eight-fold symmetry — an endless mandala at any flow.
Pro
Frost
Ice crystals branch across the glass and melt away in patches, lit with a cold glitter.
Pro
Smiley
A neon face drawn in glowing rings. Push it, swirl it, and watch it spring back into a smile.
Three ways to flow
Touch
Every finger is a brush. Multitouch streams of paint bloom under your fingertips the moment you touch the glass.
Ambient
Leave it alone and it dreams. The simulation keeps painting itself with slow, hypnotic bursts of colour.
Sound
Turn on the microphone and your music drives the currents. Audio is processed live on your device and never leaves it.
