Cyclotron is a fun and satisfying particle app. Touch the screen and the particles go wild.

Using multiple fingers changes the way the particles behave.

Great to mess with when you're bored and have some time to kill, need visual stimulation or want to keep the kids busy.

Lovely,bright & simple!

Totally worth checking it out. Very pretty bright colors & simple to use & take pics of or just play around w/& watch. I really like a lot of their creative apps!

Neat but simple

So there are ribbons of color floating around and you can shift them with your finger. There's day and night mode--night mode having a dark background and neon colors. You can take a screenshot of it anytime by clicking the dots on the bottom. It's not complicated and it's kinda soothing.

I've been searching for this forever, one of my friends had but never told me the name of it. This has to be one of my favorite time waster ever!!😜
