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

This app has been updated by Apple to display the Apple Watch app icon.

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!

Many, many uses

At first, I used it as just an app to pass the time here and there when I had a few minutes to spare and the more I used it, the more fun I had with it! From making interactive winter scenes with snow falling in the foreground with a winter picture in the background to using it as an unconventional way to draw (just make it layer by layer, taking screenshots and then using those as backgrounds). I’ve even used it as a music visualizer when headphones are in. Although I don’t always play with it, it’s one of the few apps I keep coming back to!

Great but missing obvious details

The imagery is beautiful and easy to create with the simple interface however, there seems to be no way to remove the icons for the purposes of capturing a screenshot. So you may have something great going, and want to capture the image, but it will be littered with all of the little node icons. The snapshot option crashes the app so I don’t know if that’s supposed to do this. Also, using the touch controls is great fun, but if you have other ion nodes set up that you want to alter with touches, the risk of moving them accidentally is huge. There should be a way to both hide the icons/interface , and to also/simultaneously lock the nodes in place so you can touch freely with no worries. It would get 5stars otherwise but these are such glaring issues that it’s a wonder they weren’t implemented from day 1.
