Butterfly
Two sweeping wings trace a familiar butterfly shape.
Relax with Chaos
Unwind with real-time chaos. Explore 3D attractors, colors and gentle motion.
Watch Relax with Chaos
Watch the attractors unfold in real time, with flowing trails, colors, and camera motion.

Nine systems. Nine different flows.
Explore the shapes behind the simulation. Colors and viewing angles can change their appearance.
On Google Play, Butterfly is free; the other eight require Chaos Collection. The paid Amazon edition includes all nine.

V-Shape
Explore symmetric four- or six-scroll patterns, with separate choices for the viewer and live wallpaper (Google Play only).
Watch mathematics unfold, one moment at a time.
Relax with Chaos simulates chaotic systems as flowing three-dimensional trails. Every path is calculated live on your device — a real-time simulation, never a recorded animation. Pause the simulation, rotate the view, restart it, and watch the shape build again.
Find your flow
Explore nine systems, each with its own character and carefully tuned motion: Butterfly, Spiral, Threefold, Shell, Three-Lobed, Double Scroll, Tangled Wings, Twisted Loop, and V-Shape. Adjust the flow speed to slow things down or watch the system evolve more quickly.
Nearby beginnings. Different journeys.
Display one to five trajectories of the same chaotic system. Start them close together and watch their paths gradually diverge. Automatic colors make each trajectory easy to follow as the system evolves.
Make the scene yours
Choose from curated palettes, custom colors, glow, trail styles and backgrounds. Switch between Light, Dark and OLED themes. Let the scene gently orbit on its own, explore it by touch, or reset the camera whenever you want a fresh perspective.
Discover the mathematics
Go beyond the visuals with Learn About Chaos. Explore all nine systems, their history, origins and equations, or open the Simulation Scope to see live simulation data while the attractor is running.
Keep a moment
Capture a scene, share it, or export it as a PNG. Ambient mode offers a quieter, distraction-free view when you simply want to watch the mathematics unfold.

Purchase and availability
The Google Play edition includes Butterfly for free. A one-time Chaos Collection purchase unlocks the eight additional systems. The Amazon edition is a paid app with all nine systems included and no in-app purchases. Neither edition has ads or subscriptions. Downloads are available on Google Play and Amazon Appstore. Preview images and video may show Chaos Collection content.

Read the privacy policyCommon questions
Can I use it offline?
The simulations run on your device. Google Play purchases, ownership checks, and restoration require store connectivity.
Which systems are included?
Google Play includes Butterfly for free. A one-time Chaos Collection purchase unlocks the other eight systems. The paid Amazon edition includes all nine.
How do I restore the Collection?
Use the Collection restoration controls with the Google account that owns the purchase. A pending payment unlocks access only after it completes.
What device do I need?
The Android app requires Android 8.0 or later and OpenGL ES 3.0. Check the marketplace listing for device compatibility.
Are my images or preferences uploaded?
Preferences stay local. PNG exports go to a location you choose, and sharing gives your chosen destination access to the image. Exported and shared copies must be deleted separately.
