Fluid is a pool of colour that behaves like real ink in water. Drag a finger through it and it swirls, blooms and slowly settles, mixing and clouding the way liquid actually does. There is nothing to do with it and nothing to win. It is simply a beautiful, responsive thing to stir, and to watch keep moving after your hand has stopped.
Why it exists
Some screens are for getting things done and some are for the opposite: a small pocket of calm you can reach for and put down. Fluid is the second kind. Stirring ink is one of those quietly satisfying things, like watching rain on glass, and this is a version of it that is always to hand, that reacts to you, and that you can tune to the colours and the mood you want that day.
How to play
Touch and drag to stir the colour. Change the palette, the mood and the flow, and let it drift. There is no goal, so there is no wrong way to use it. Sit with it while it soothes, and close it when it has done its job.
Keep the moment
When the ink arrives somewhere you love, the little KEEP THIS button saves that exact frame as a picture, stamped small in the corner, from your own hands to your own photos. Nothing is uploaded anywhere; a stir you made is yours to keep. Underneath, the swirls are a real-time solution of the Navier-Stokes equations, the same mathematics that describes smoke, weather and cream in coffee, so every picture you keep is a genuine portrait of turbulence you caused.
