This release marks a notable addition to Apple’s app ecosystem, highlighting a focus on accessible, contemplative digital art.

The core innovation of RHEO is its simplicity: users interact with a single finger to produce liquid light that swirls, blooms, and settles, with no need for tutorials or complex controls.

Paint with light.

A single fingertip becomes a river of glowing color. Touch the screen and liquid light blooms, swirls, and slowly settles — a calmer kind of beautiful, in the palm of your hand.

01 Gorgeous by default · no skill required

You can’t make an ugly one.

Most creative apps ask you to learn them first. RHEO asks nothing — every stroke trails stardust, catches bloom, and scatters light like sun through water.

Effortless beauty

Drag slowly for silk, flick fast for a burst, pinch the world into a vortex. Whatever you do, it looks like art.

Minutes that slow you down

No feed, no score, no streak to protect. Just a fluid that reacts to you and settles gently back to calm.

It responds to you

A warm ambient score and subtle haptics rise and fall with how much you move — sight, sound, and touch in sync.

02 The whole pitch is the first thirty seconds

“You touch it, it glows, and you understand the app completely.

Breathe mode

The fluid breathes with you.

The whole fluid swells on the inhale and eases on the exhale — gravity itself leans with the rhythm. It’s box-breathing you can actually see, pacing you without a single number on screen.
