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

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.
