Glidecraft vs Cell Zoo

Glidecraft is a physics-based drawing game where you sketch track lines and watch a ragdoll rider glide across them. Draw freehand with the brush, lay precise lines with the pencil, or use the straight-line tool to build ramps, loops, and jumps. Three line types give you control: blue lines are normal rideable track, red lines give a speed boost, and green lines are scenery with no collision. Hit play and watch your rider navigate the course with realistic Verlet physics. The ragdoll body, trailing scarf, and sled all react naturally to every bump, drop, and curve you've drawn. Features: - Freehand brush, pencil, and straight-line drawing tools - Eraser tool for quick edits - Three line types: normal, acceleration, and scenery - Undo and redo support - 5 rider skins: classic, hotdog, penguin, robot, and snowman - Adjustable playback speed (0.5x, 1x, 2x) - Pinch to zoom, two-finger pan - Save and load multiple tracks - Fully offline — no accounts, no ads, no data collection

The most beautiful cellular automata simulator on iOS. Watch alien organisms evolve in real time. Touch them, breed them, teach them to sing. Place them on your desk in AR. Cell Zoo is a pocket terrarium for mathematical life. ELEVEN LIVING WORLDS Slime molds that solve mazes. Continuous creatures that swim, split, and breathe. Chemistry that paints leopard spots and coral. Electromagnetic waves, self-assembling DNA, even your own words dissolving into life. New in 2.2: Chimera, where four rival physics share one map and fight over the borders. Every world runs real math at up to 120 frames per second, and none of them behaves the way you expect. IT GROWS INTO YOUR PHOTOS Hand the colony a picture and watch it grow into the bright shapes — your face, your handwriting, your dog. A living sketch, not a copy. IT LISTENS. IT SINGS. Turn on Hearing and the colony moves to your music: bass makes it surge, treble makes it shimmer. Turn on Voice and the simulation sings back — a generative soundtrack drawn from the colony's own rhythms, never the same twice. A NEW CREATURE EVERY DAY Hatch the Daily Specimen each morning. Creatures you keep sync across your devices with iCloud. SHARE WHAT YOU GROW Send any creature by link. It hatches on your friend's device exactly as you made it — same genes, same colors, same behavior. BREED THEM (Premium) Cross two creatures and hatch the offspring. Mutate genomes. Pit colonies against each other in the arena and carry the winner's line forward. 30+ RENDER MODES (Premium) Photoreal protoplasm, holographic diffraction, infrared, liquid metal, bioluminescent deep-sea glow, aurora, soap film. Every mode is a handcrafted Metal shader. AR MODE (Premium) Grow a colony on your table, floor, or wall. In 3D, a living structure floats in your room — walk around it. Walk through it. TUNE EVERYTHING Sensor angles, diffusion rates, decay, species counts — every slider changes behavior live, and all of them are free. Capture the results in photo mode with pro exposure and cinematic filters. Built native with Metal: 120Hz ProMotion, HDR bloom, MetalFX upscaling. No accounts, no ads, no analytics. Premium is a single one-time purchase. Terms: https://cellzoo.app/#terms
