Some apps are better with no goal in them at all
Almost everything on a phone wants something from you: a streak kept, a level cleared, a notification answered. A toy asks for none of that, which makes it oddly hard to ship — there is no progression to sell, no defeat to soften with a purchase, no reason to nag anyone back. The business case is simply that people like it.
So Fluxen has no score, no timer, no achievements and nothing purchasable. It opens where you left it, it does what your hands tell it, and it closes without a word. The only thing we optimised for is how the fluid feels when the phone tips.
Everything is simulated on the device in real time. Nothing is streamed in, nothing is pre-rendered, and no two pours are ever quite identical.
tilt, touch, watch it flow · nagni, se dotakni, opazuj
A living, tilt-reactive playground where glowing liquid, sand, bubbles and particles slosh across the screen in answer to how you hold and move the phone. No score, no rush — a toy for the hands and the eyes.
Switch between substances, each with its own feel, and tune the physics until it behaves the way you want: gravity up or down, flow thick or thin, bouncy or sticky. Drop obstacles in and let the fluid wind around them, pick from a spread of colour themes, move between distinct sandbox scenes, and save the setups you keep coming back to.
What each substance actually does
One small tank, one fixed pour, no tilting and nothing to tune. Pick a substance and watch a batch fall through — the point is the difference between them, which is the part a screenshot can never show you.
Liquid settles flat and fills whatever it is poured into — the particles slide over each other instead of stacking.
No tilt, no gravity dial, no obstacles, no themes, no scenes and nothing saved — this tank only pours, straight down, forever. Fluxen is the other side of that: the whole thing answers to the phone in your hand, and every setting above is yours to move.
