New mode: Smoke Lab. Watch smoke rise from chimneys, then split and curl around walls. Spray smoke with your finger and follow where the air goes.
Move wind and liquid with your fingertips, then turn the motion into something of your own.
Swipe the Flow is an interactive fluid simulator that responds to touch in real time. No special knowledge or complicated controls are required—just swipe, draw, and watch flows and vortices come alive.
CREATOR UPDATE
Add a photo, logo, or basic shape as an obstacle in Wind Tunnel.
• Import photos and logos
• Remove backgrounds on your device
• Move, rotate, and resize each layer
• Watch wind flow around your images
• Save and share the result as a photo or video
THREE WAYS TO FLOW
• Wind Tunnel
Draw walls or place photos and logos, then watch the wind bend and flow around every obstacle in real time.
• Liquid Art
Create, push, merge, split, and stretch liquid drops. Tilt your device to shape them into living, shifting forms.
• Swipe the Flow
Swipe freely across the screen to create colorful currents and spiraling patterns.
CHALLENGES
• Wind Paths
Draw walls to guide the wind into the target. Ten stages in order: a gate in the middle, a backdraft, a wind shadow, a 30/70 split, a vortex.
• Wind Maze
Carve a route through the solid block and get the wind out before the clock runs out. Ten stages: around a boulder, spin a vortex, split three ways. Your latest and fastest escapes are both recorded.
Stages 1-5 are free in both games; stages 6-10 are included in Pro. Compete with friends on Game Center leaderboards and achievements.
Share any cleared challenge as a photo stamped with the level and your time.

I like this, please add supersonic mode and Reynolds number for subsonic flow. Happy to help with aerodynamics concepts
Developer Response
Thank you! Supersonic is a different beast — not on the table. And I keep numbers off screen on purpose: this one is meant to be played by feel, not read. But the regime change is already in there — slide "Duration" in Wind Tunnel and watch smooth flow break into chaos. Kind of you to offer 🙏

Developer Response
Thanks for taking the time to write this. There's no pinch-to-zoom yet, so I want to make sure I fix the right thing: were you trying to see more of the board at once, or was the view getting covered by your hand while drawing? Either way I'm looking into it for a coming update.
