Ions is back, recharged and better than ever! The sequel to the staff-favorite particle simulation allows total control over the look and behavior of your creations. Ions 2+ also supports iPhones and iPods as well as iPads!

Your ions can now change color and size based on age, speed, direction, and other parameters! Change shape, leave trails, change the background, and more! Use your device’s accelerometer to react to gravity or add turbulence and drag for more variety. You also have both rectangular and polar grids for precise placement.

Why stop at only 20,000 particles? With Ions 2+, you can raise the limit up to 100,000 on faster devices.

Of course you can still save your favorite layouts, as well as any custom looks you’ve created.

Ions 2+. I'm positive you'll love it.

What’s New

Version 1.2

And now a big update, years in the making!

• Emitters have more controls: Radius, Twist, and Randomness.
⁃ Emitters can now emit within a specified radius to spread out your ions. You can also control the twist and randomness of their initial directions. Tap the dueling arrows on the bottom left of an emitters’ controls to see the new ones.
• Use colors from background images.
⁃ You can now have your ions take their colors from the background image. They can either sample the color once at birth, or continuously over their lives. That’s right. You can now paint with Ions2+.
• Background images.
⁃ You can load any image from your pictures library to use as a background image. You can then resize and place it within Ions2+ to put it right where you want it.
• Transparency.
⁃ There is now a separate curve to control the transparency (aka “alpha”) of your ions. Have them fade out, flash, or simply layer beautifully on top of each other.
• New layouts:
⁃ Echoes, Dust, Twirl, Watercolor, Corners, Sun, Eye. Hairbrush, Galaxy, Bursts. Stars. Chips, and Chase.
• More ions.
⁃ Devices are fast these days, so why not allow 200,000 ions at once? Why not, indeed.

If I could rate this app 10 stars, I would! Of all the outstanding games and apps out there for iOS, Ions 2+ is one of the very best I’ve come across. You can get lost in this thing for hours just fiddling around with all the various buttons and sliders and man does it pay off! You can save all of your creations and delve into them any time you need a fix on that trippy thing you made. Really a very cool and relaxing app. Not at all a waist of time but more of an enhancement to time. Thanks for this hidden gem and I hope the word gets out and maybe even CNN will mention it. They should. It’s that good! And it’s only 99 cents!

I love interactive particle/line apps and this is the best I've found. I have many others with titles containing works like particles, lines, linear, laser, fireworks, lightning, gravity, plasma, fluid, toy, and yes the weird names too.

This app has flexibility and depth. To start, it has a wide variety of precanned configurations to choose from. You can modify these, or start from scratch, and then store them as your own interactive creations. Nice!

The emitters and fields, a great concept, are fully configurable and a lot of fun. Many many other configurable items too. Help screens clearly explain options. Pure eye candy in a huge variety of forms.

Nope, I have no connection to the developer. (I often wonder that when reading reviews)

Only enhancement I'd like is an option for more than 100,000 particles. Ok, true, that's a lot, and more than most others offer. But with current cell phone processing power, why not!

very special and very well thought out.
real time interface controls set this apart from any other visualizer out there by the endless variations and surprises you get by easy tweaks.
one nice feature is being able to import a picture as a background and overlay the color motions on it.
really fun!
