CellScape vs KINRAKU

CellScape is a microscope adventure where learners explore a living freshwater pond and learn real biology through play. In Little Learner mode, you tap, observe, and discover with simplified controls. In Explorer mode, you run experiments by adjusting light, nutrients, and temperature, then read population trends on a 60-second graph. What you can do • Observe freshwater organisms such as Chlorella, Paramecium, rotifers, diatoms, snails, and decomposers. • Run one-variable cause-and-effect experiments. • Unlock discovery stamps, learn cards, and challenge missions. • Learn ecology and microbiology vocabulary in the in-app glossary. • Switch between metric and imperial temperature units in Explorer mode. Privacy-first design • No ads • No analytics or tracking SDKs • No accounts or chat • Local-only save data • Parent-gated settings and reset actions

KINRAKU is a visual-first educational app for microbiology, infection dynamics, and evolution. The 13th installment in the SUUGAKU / BUTURAKU / DENRAKU / HARAKU / NETURAKU / SEIRAKU / KORAKU / RYORAKU / RYURAKU / KAKURAKU / KIKARAKU / KAGAKU series. This time the theme is "microbes, infection, and evolution." Twelve core topics from high-school to introductory-university biology, all delivered through beautiful simulations and hands-on interaction. [12 Features] - Microbe Atlas 17 species across Bacteria, Archaea, Eukarya, and Viruses. Tap any card for shape, size, habitat, and role. - Cell Structure Cross-sections of all three domains. Bacterial nucleoid, plasmids, and flagellum; archaeal S-layer and ether-linked membrane; eukaryotic nucleus, mitochondria, ER, and vacuole — all labeled. - Cell Division Binary fission, budding, and sporulation animated through one full cycle. Watch N(t) = N₀ · 2^(t/g) climb as you tune the generation time. - Petri Dish Tap to inoculate three different microbes. Adjust nutrient, temperature, and pH to see colony growth shift and species compete where they meet. - Biofilm Planktonic cells attach to a surface and secrete an EPS matrix to build a 3D community. Watch the four stages — attachment, microcolony, maturation, dispersal — plus quorum-sensing switching and the high drug resistance inside the matrix. Tune attachment and growth rates. - Chemotaxis Bacteria swim toward nutrients (attractants) and away from toxins (repellents) via run-and-tumble. Move the source with a tap or drag and watch the population climb the gradient and aggregate. Tune cell count, sensitivity, and swim speed. - Fermentation Switch between lactic acid bacteria, yeast, and koji mold. Watch the substrate fall and products (lactate / ethanol / CO₂ / enzymes) accumulate, with live pH readout. - SIR Simulator 180 agents wander and infect each other. Real-time epidemic curve, live S/I/R/V counts, and the basic reproduction number R₀. Sliders for β, γ, mobility, and vaccination dramatically reshape outbreaks. - World Map Metapopulation SIR over 7 Japanese regions, coupled by travel. Press lockdown to halt cross-region transmission; apply vaccination and observe herd-immunity effects. - Immune System Macrophages follow chemotactic gradients, chase pathogens, and engulf them. Tilt the balance between immune count and pathogen growth and watch infection establish or clear. - Resistance Evolution Three sliders: antibiotic concentration, mutation rate, growth rate. Apply pressure and watch susceptible cells die while rare resistant mutants take over — the resistance histogram shifts right as evolution unfolds. - Tree of Life The full tree from LUCA to the three domains and major clades. Pinch to zoom across billions of years of evolution. [Highlights] - Formula reference sheet on every screen - Live dynamics for SIR, logistic growth, and selection - Japanese / English support - Dark mode / Light mode - Clean, intuitive UI - Only a small banner ad at the bottom [Recommended for] - High-school biology and university microbiology / public-health students - Anyone wanting to intuitively grasp epidemic models and antibiotic resistance - Teachers looking for interactive teaching materials - Anyone curious about how life evolved at the microscopic scale
