Particles - An Interactive Particle System

By String Theory Software

Open iTunes to buy and download apps.


Particles is an interactive particle system - a field of dots that are attracted to your touch. All the rules of physics, such as momentum and friction, apply. To use, simply touch the field of dots and they will accelerate towards your finger. Depending on how you touch it, you can create a literally infinite number of beautiful patterns.

***** UPDATE *****
You asked, we listened - you now have full control over the number of particles, as well as gravity and friction, as well as the ability to invert gravity (particles are repelled by your finger). Also, Particles now supports multi-touch, so you can interact with it in more ways!

Please note that Particles is designed to run on iPhone 3GS, iPhone 4, iPod touch generations 3 and 4 and iPad. Due to the nature of the animations in Particles, Particles may run poorly on earlier devices.

What's New in Version 3.0

This new update contains many new and exciting features, including multitouch and total control over the environment. A full features list is included below:

+ Multitouch.
+ Control over particle count, gravity and friction.
+ Invert gravity - now you can repel the particles as well.
+ All settings are now saved when you close the app.
+ Because you can lower the particle count, Particles now runs better on iPhone 3G and earlier iPod touches.
+ Added one new color scheme.
+ Various efficiency improvements.

Please note that this multitouch edition Particles may run more slowly on pre-iPhone 4 devices. To remedy this, simply slide the 'particle density' slider down.
