This revolutionary application was developed for medical educational purposes and offers users the opportunity to enjoy interesting 3D content for biology education. Users can view 3D images on an iPad or iPhone either with or without red/cyan glasses. An *adaptor allows connection to a 3D TV where vivid 3D content can be viewed. Content includes 3D electron microscopic images and 3D CT content as well as 3D movies. Some 3D CT content allows users to interactively adjust the viewable angle, size, and transparency and observe living organisms from the inside. Students can benefit from this content for self-study. **The application is also useful when used accompanying lectures and or presentations displayed on large 3D TVs and or 3D projectors. New biology, medical, and healthcare related 3D movies and 3D interactive content suitable for educators in related fields will be introduced in the near future. *3D content is viewable on 3D TVs using the Apple Digital AV adaptor compatible with your TV or with Apple TV. **For 3D display, units compatible with side-by-side input is required. Information pertaining to compatibility issues are available at support site. Application characteristics 1. Stereoscopic viewing 2. External Display support for some models 3. Content view history 4. Display user's 3D content 1. Stereoscopic viewing Content is viewable as follows: Anaglyph: Stereoscopic viewing with red/cyan glasses Glasses-free stereoscopic viewing: Glasses-free viewing of images placed side-by-side as one stereoscopic image. This method corresponds to cross-eyed view and parallel view methods. 3D TV: Used to display content on a 3D TV or a projector compatible with side-by-side format. 2. External Display support for some models Content display on an external monitor is supported for some models. When using an iPad or iPhone, you can display the content on a large TV screen and enjoy simultaneous viewing with others. (Use of a high-performance iPad or iPhone is recommended for this function.) 3. Content view history Content accessed is stored. This function facilitates searches for frequently viewed content and the alternate display of multiple content items. 4. Display user's 3D content Transferring photos by iTunes, display user's 3D content with Stereoscopic viewing. Not only on a iPad/iPhone but on a 3D TV or a projector.

KINRAKU

Read full description

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

Verdict

The call

The clearest difference is in-app purchases: KINRAKU at none against Actioforma KOS's 2. KINRAKU also leads on update cadence (every 3 weeks vs every 2 months). Actioforma KOS's advantage is ads (none vs shown) and iOS requirement (7.0 vs 13.0). On price and device support there is nothing between them.
