Particlescape is an interactive particle and gravity simulator designed to create beautiful patterns at your fingertips. This free iPhone app allows users to generate particles by simply touching the screen. With the ability to generate up to 8000 particles per second per touch, it feels like you're magically summoning particles from the ether.

One of the standout features of Particlescape is its high-density rendering. Particles in areas of high density are rendered at a higher resolution, allowing for finer detail and a more visually appealing experience. The app also supports up to 10 simultaneous touches on iPad and 5 on iPhone, providing endless visual possibilities.

For those with 3D Touch-enabled devices, such as the iPhone 6s and 6s Plus, pressing harder on the screen will generate more particles or increase the force of gravity. This adds an extra layer of interactivity and customization to the simulation.

With extensive optimizations, Particlescape can support up to half a million particles on screen, making it one of the most powerful particle simulators available. Please note that older devices may support fewer particles, but the app is optimized for iPhone 6s, 6s Plus, and iPad Air 2.

Overall, Particlescape offers a visually stunning and interactive experience for those looking to create beautiful patterns with their fingertips. Whether you're a casual user or a digital artist, this app provides a captivating way to explore the world of particles and gravity.
