The double pendulum is a simple mechanical system that displays chaos. The motion of the pendulum arms can be complex and unpredictable, with even minute changes leading to very different trajectories. This app accurately simulates the physics of a frictionless double pendulum, so you can explore and enjoy the complexity and beauty of mechanical chaos.
Tiamat

- Create and customize rulesets
- Design and save intricate patterns
- Transform existing patterns
- Adjust simulation speed
- Access a library of pre-built patterns
- Choose from field presets
- Supports BS, SB, and HROT rulestrings

Tiamat turns cellular automata into a creative, relaxing sandbox for patterns, rules, colors, and discovery. Build living worlds from simple rules, then watch order, chaos, gliders, oscillators, and unexpected structures emerge. Start with familiar Game of Life-style behavior, import or export rulestrings, tune simulation speed, paint directly on the field, and save the fields, rules, gradients, and patterns you want to revisit. What you can do in Tiamat: - Explore Conway-like cellular automata with wrapped, borderless fields. - Create, edit, save, import, and share rules with BS, SB, and HROT rulestring support. - Paint cells by hand, place saved patterns, or generate random fields. - Customize gradients and fading to make simulations easier to read and more beautiful to watch. - Save favorite worlds, layers, rules, colors, and patterns for later experiments. - Learn cellular automata concepts with built-in help and changelog articles. Whether you are studying emergent systems, looking for generative art inspiration, or just want a calm mathematical sandbox, Tiamat gives you precise controls without getting in the way.

Verdict
The clearest difference is in-app purchases: Double Pendulum at none against Tiamat's 6. Double Pendulum also leads on iOS requirement (11.2 vs 26.0). Tiamat's advantage is ratings volume (117 vs 3). On price, rating, review sentiment and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Tiamat sells 3 one-off in-app purchases. Double Pendulum asks for nothing beyond the download.
Tiamat holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Tiamat has 117 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 100% of Double Pendulum's written reviews are positive against 92% of Tiamat's, so the app with the better star average is not the one people write more warmly about.
