I was so mesmerized, I had to record a video. In it, my son Izaiah is just four months old and already fascinated by the Uzu app. The way it responds to his little fingers tapping the screen is nothing short of magical.

What Is the Uzu App?
Uzu is a kinetic multitouch particle visualizer. That might sound technical, but here is what it really means: Uzu is a vibrant, touch-responsive light show that you control with your fingers.
Originally created for the iPad, it is now available for iPhone and iPod Touch as well.
With a single tap or swipe, the screen bursts into color. When Izaiah touched the screen, it lit up like fireworks. When he let go, the lights fizzled out. It held his attention longer than a rattle ever has, and when it finally lost his focus, he let out a baby scream that said, “Bring back the lights!”
Why Uzu Works for Everyone
This app is stunning. I handed it to my older kids on the way home from Austin, and it kept the car quiet the entire ride. From my four-month-old to my five-year-old and seven-year-old, and even my husband, everyone was hooked.

As a 31-year-old mom, I can say confidently this app appeals to all ages. Whether you are looking for something visually soothing, fun for the kids, or just want to zone out for a bit, Uzu delivers. It deserves a spot on the iPad demo tables at Apple Stores if it is not already there.
Uzu App Pricing
- Uzu for iPad: $1.99
Both versions are available in the App Store.
Uzu App Features: A Deeper Look
Created as a math-meets-physics visual experience, Uzu is like a digital version of everything you loved as a kid: spirographs, lava lamps, fireworks, and laser shows.
Points of light swirl, shoot, and react to your every move. You can freeze visuals in 3D space and control the show using different multi-touch gestures.
Here are the ten modes of touch control built into Uzu:
- 0 Touch: Brownian motion with boundary wrap
- 1 Touch: Emanate and radiate
- 2 Touch: Pinch attraction with boundary bounce
- 3 Touch: Tri-point vortex
- 4 Touch: Quad-point inverted vortex
- 5 Touch: 3D freeze and translate
- 6 Touch: 3D oscillating mass
- 7 Touch: 3D tri-arm spiral
- 8 Touch: 3D warp and inverted translate
- 9 Touch: Springy space ribbons
- 10 Touch: Adjust color and particle size
Final Thoughts
Whether you are using it to entertain your toddler, impress your older kids, or simply chill out after a long day, the Uzu app is more than just a visualizer. It is an experience.
For just under $2, it brings endless entertainment, creativity, and calm.
