A relaxing fluid simulation you play with your fingers: a pool of color that answers every touch. Draw across it and you pull a band of color through the flow. Tap and a drop bursts open. Rest a finger and a glowing plume rises. Behind it runs a real fluid solver on the GPU, up to a hundred and twenty times a second. No video, no loop: what you see was computed a moment ago and will never come back quite the same. TWENTY LOOKS Ink on water, northern lights, marbled paper, smoke, neon, deep sea. One for every mood — and if you would rather not choose, the dice hands you one. EVERYTHING IS A SLIDER Vorticity, color decay, resolution, pressure: the knobs of the method itself, not a few filters laid over it. The pool keeps painting while you drag them, so you see what you are doing straight away. MORE THAN FINGERS Let the music in the room drive the flow. Use your own photo or the camera as a color source. Paint walls the color has to flow around. And record what came out of it. No goal, no score, no progress. A pool that answers back. Every third roll of the dice plays a short video ad. Vortis Pro is a one-time purchase that unlocks the effects, your own image sources and the solver's own controls — and removes the ads.

Verdict
The clearest difference is in-app purchases: SpinningCat at none against Vortis's 1. SpinningCat also leads on ads (none vs shown). Vortis's advantage is update cadence (every 5 days vs every 19 months). On price, device support and iOS requirement there is nothing between them.
