### 5/5 — Rulestring imports

*2023-11-28, version 1.6.2*

I want a feature to be added to the app where you can import specific rulestrings in the birth/survival format, the survival/birth format and more rulestring formats as well as allowing Generations rules (rules with more than 2 cell states) to be implemented.
Thanks for reading this.

### 5/5 — Requests for features

*2022-09-08, version 1.4.0*

I have some requests, please add the ability to make your own rules, add a way to control size of saved patterns as 2x, 4x the original etc, an undo button, a button for screen capturing, and for screen recording, love the app thank you :)

### 3/5 — Could’ve been better.

*2026-07-03, version 2.4.0*

The pop-up asking to donate is very annoying and Some strings straight-up DONT WORK AND INSTEAD BECOME A CHAOTIC MESS! WHY!!!

### 5/5 — Awesome!

*2026-05-26, version 2.3.2*

I absolutely love this, I’ve been trying to find an app like this and this one works perfectly for that. I have a suggestion for a new feature though, the ability to have multiple different types of cells, with different rules I think would be a great improvement (:

### 5/5 — Cells

*2026-04-23, version 2.3.2*

This app is amazing! I can do anything my heart desires and all with no ads! The support pop is slightly annoying but nonetheless it’s great!

### 5/5 — Good

*2025-12-22, version 2.3.1*

Good, free, functional, no ads, no purchases, good, list entry duplication error

### 5/5 — Feature Requests

*2025-10-14, version 2.3.0*

I would like a way to control the speed of the pattern (buttons or a slider), Langton’s Ant formatted rules (L and R), and the ability to use and create multicolor rules, like Generations (and the ability to input rules in multicolor formats)

### 5/5 — Very good!

*2025-06-27, version 2.2.1*

It works super smooth! Even when 1 million blocks, pexil, cells, whatever you call them! Honestly this is amazing!!

### 5/5 — ❤️❤️❤️

*2025-03-05*

I absolutely love everything about this app from the very true title screen to the intricate Turing Machine world featured here. This is truly a work of art. I like how the cover is like a (really pretty :) ) screenshot of a pattern from the bug rule.

**Developer response:** Thank you for your feedback! It motivates to continue developing the app

### 5/5 — Interestingly odd

*2025-02-15, version 2.2.1*

Omega fun and crazY and I like how it says in the beginning there was only chaos. FIN

### 5/5 — Yes

*2025-02-15, version 2.2.1*

Very cool and very cool and very cool

### 5/5 — Incredible

*2024-08-29, version 2.1.4*

I’ve always enjoyed watching Conway’s Game of Life. This is truly inspired. Wonderful, thank you. I'll try to chill out using this next I’m stressed out. Chaos truly is beautiful.

### 5/5 — Best Cellular automata program on the appstore

*2024-05-02, version 2.1.2*

This program truly goes above and beyond with its ui and features. Once you read the help guide making custom rulesets is a snap! Customizable color palettes, fade speeds, zooming is easy, drawing is easy too, everything about this program is so user-friendly which goes way beyond other programs’ heights. Also nothing is blocked behind a paywall. The in-app purchases is really just a donate button. It’d be kinda cool if there was some ‘turbo mode’ or something to make the program run at hyper-speed, but I understand that could be hard for some devices to handle.
