If you are into strange attractors, chaos theory, or just funky 3D forms, you’re going to love iAttractor. This iPhone app puts a 3-dimensional strange attractor right in the palm of your hand. Zoom in, out, rotate around, adjust parameters. The lite version (free) gives you the Pickover attractor to play with, whereas the full version ($0.99) also gives you two versions of the Lorenz attractor and two “polynomial” attractors, bringing the total to five. The full version also lets you change background color and attractor color, view parameter details, and save a snapshot of the attractor to your photo library.

3/5 stars

Cool, but needs a bit of UI polish.

The sliders lack labels or any sort of descriptions. On a complex app like this, a little help could go a long way in increasing ease of use.

4/5 stars


Simple app that does what it is supposed to. It would be nice to be able to better control the attractors as you are spinning them around (lateral movement should be enabled??).

All in all, worth a buck even though the controls are cheap, lacks a time-step option, and needs impoved viewing nav.

4/5 stars

Great Start

As a longtime Chaoscope user, I was very excited to see something like this come to the app store. What this app does now is certainly impressive. Smoothly spinning around attractors was really a delight, and pinch zoom works wondefully.

As for improvements, I'd suggest a two-finger drag for panning movements. It would also be nice to be able to set the app to render something more fully - aggregate more particles in progressive, slower-than-realtime fashion once the view is locked. Then let the user export an image (hopefully one larger than screen res). Adding color gradients, if possible, would give renders an awesome touch.

Really looking forward to updates. I'll be sure to recommend this app. Heck, add a few more attractors and the improvements I suggested above, and I could see myself paying $3-5 for this, easy.
