Read full description

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 call

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.

Both are free to download. Tiamat sells 3 one-off in-app purchases. Double Pendulum asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

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.
