Pixel Evolution Lab vs Dot.Entity

Watch life emerge from a few simple rules. Pixel Evolution Lab is a beautiful, fast simulator for cellular automata – the mathematical worlds made famous by Conway's Game of Life. Each cell only looks at its eight neighbors. Yet out of random noise, gliders take flight, oscillators pulse and whole cities of still lifes appear. No plan, no script – order simply emerges. Version 2.0 is a complete redesign: the simulation fills the entire screen, the controls float above it, and every change you make in the lab is visible instantly. EXPLORE • Full-screen simulation powered by Metal – smooth even with hundreds of thousands of cells • Pinch to zoom, drag to explore, double-tap to see the whole world • Play, pause, single step and speeds from 1 to 60 generations per second, plus Turbo • Afterglow: dying cells fade out slowly and reveal motion and history • Evolution tracker with population, density, births and deaths DISCOVER • Pattern library with explanations: glider, spaceships, pulsar, pentadecathlon, the Gosper glider gun and famous methuselahs like the R-pentomino, Acorn and Diehard • 18 universes with different laws of nature – from Conway's Life and HighLife to Day & Night, Maze, Coral, Amoeba and Replicator • 9 color worlds, from phosphor green to amber, ice, magma and paper CREATE (PRO) • Draw and erase cells right in the field – with your finger or Apple Pencil, with undo • Build your own rules in B/S notation • Mix your own colors • Save your creations in your own gallery RELAX • Ambient mode hides all controls, keeps the screen on and starts a new world whenever the current one settles – a digital campfire for your desk • Share beautiful pictures of your worlds • The app remembers where you left off FREE AND FAIR The free version includes the full simulation with zoom, single step and Turbo, three universes, three color worlds, afterglow and four classic patterns. Pro unlocks everything else with a single one-time purchase – no subscription. No ads. No tracking. No account. Your worlds stay on your device. Download Pixel Evolution Lab and start your first universe.

Dot.Entity You tap. Cells are born. They spread, collide, change shape — the way a short video captures mold growing or fruit decaying. That kind of quiet time-lapse, in your palm. Each cell becomes the seed of a structure no one can predict. Watch it unfold. --- [ What you can do ] ・1-minute tutorial covers the four B3/S23 rules ・Tap the board to drop random presets (Glider, Blinker, Block...). First 10 taps follow a curated sequence so motion is immediate ・47-entry Lexicon (23 still lifes, 20 oscillators, 4 spaceships) auto-populates as you discover patterns. Each entry carries its discovery year, discoverer, historical significance, and trivia ・COMBO mechanic — the longer motion sustains, the higher the counter climbs across 9 distinct tiers (color / sound / haptic). At the top tier the HUD pulses in rainbow ・Dramatic sessions auto-save to REPLAYS (combo peak ≥ 300). 16x time-lapse playback, Shannon entropy graphs, and automatic key- moment markers let you analyze past evolutions ・PLAYGROUND for designing your own patterns (up to 50 saved). EDIT supports finger-drag continuous drawing, each cell ringing a pentatonic note. 5 practice challenges (Block, Glider, R-pentomino, Acorn, Diehard) ・"Today's Challenge" — daily 8x8 puzzle, clear within 5 moves. Optional hints. 7-day sparkline with streak counter ・Share moments as text or image. Photo-library permission is requested ONLY if you choose "Save Image" from the share sheet ・Glossary with 35 English terms — still life, oscillator, spaceship, methuselah, Glider Gun, Universal Constructor, Moore neighborhood, chirality, puffer, Turing completeness, and more. 14+ terms include live preview animations. Daily-rotating trivia card ・26 achievements (Discovery 6 / COMBO 8 / Daily 7 / Meta 5). Stats panel + "Coming up" progress panel. 3 "hint-free clear" achievements give the Daily Challenge a self-best axis ・Daily streak counter with personal-best record --- [ Made for ] ・People who enjoy fast-motion videos of natural processes ・Anyone curious about Conway's Game of Life or cellular automata ・Fans of digital fidgeting and tactile interfaces ・Commutes, waiting rooms, winding down before bed --- [ Design principles ] Zero in-app purchases, ads, social features, or data collection. Fully offline. Sensory-friendly: haptic / audio / visual intensity each adjustable per-axis (off / soft / medium / strong). Auto-detects iOS Reduce Motion and Reduce Transparency. Full VoiceOver support. Predictable, low-stress: all rules in the 1-minute tutorial, no hidden mechanics, no failure states, no time limits. Daily Challenge hints are opt-in. Collection-first: 47-form Lexicon + 26 achievements make "collect them all" the primary axis. Instant tap reward — haptic + visual + audio fire together. --- [ About cellular automata ] Conway's Game of Life, announced by mathematician John Conway in 1970, is the most beloved cellular automaton in the world. From four simple neighbor-counting rules emerge spaceships, oscillators, glider guns, even Turing-complete computation. For over 50 years enthusiasts have discovered new patterns — Glider Gun (Gosper 1970), Pulsar (Conway 1971), Eater 1, Pentadecathlon, LWSS, MWSS, HWSS — all included here with their historical context.
