KAGAKU vs Elebox

KAGAKU is a visual-first educational app for learning chemistry through direct interaction with simulations. The 10th installment in the SUUGAKU / BUTURAKU / DENRAKU / HARAKU / NETURAKU / SEIRAKU / KORAKU / RYORAKU / RYURAKU / KAKURAKU series. This time the theme is "chemistry." Ten core topics from high-school to introductory-university level, all delivered through beautiful animations and hands-on manipulation. [10 Features] ▶ Periodic Table All 118 elements color-coded by category. Tap any element to see its atomic number, mass, electron configuration, and electronegativity. ▶ Atom Structure Animated Bohr model. Watch electrons orbit quantized shells for 13 representative elements (H through Cu). ▶ 3D Molecules 12 molecules rendered as ball-and-stick models: water, methane, ammonia, CO₂, ethanol, benzene, ethylene, acetylene, glucose, and more. Drag to rotate, or let them auto-spin. ▶ Chemical Bonds Visualize ionic, covalent, and metallic bonding. Electronegativity difference auto-classifies the bond type; animations highlight the distinct electron behavior of each. ▶ Equation Balancer Six reactions: methane combustion, iron oxidation, water synthesis, Haber process, photosynthesis, and neutralization. One tap reveals balanced coefficients plus an atom-count check for each element. ▶ Flame Test Li, Na, K, Ca, Sr, Ba, Cu — watch each element burn with its signature color above a Bunsen burner, alongside the emission spectrum with wavelength labels (nm). ▶ Acid-Base / pH Real-time strong-acid / strong-base titration curve. Switch between BTB, phenolphthalein, and methyl orange indicators and see color change with pH. ▶ Electrochemistry Animated Daniell cell. Electrons flow through the external circuit, Zn²⁺ and Cu²⁺ ions drift in the solutions, EMF 1.10 V is displayed live. ▶ Gas Laws PV=nRT particle simulation. Freely change temperature, volume, and particle count and watch Brownian motion drive wall collisions — the source of pressure. ▶ Organic Chemistry A visual field guide to alkanes, alkenes, alkynes, aromatics, and functional groups (-OH, -NH₂, carbonyl). Eight representative molecules you can rotate in 3D while learning their properties. [Features] • Formula reference sheet on every screen • Live values and equations • Japanese / English support • Dark mode / Light mode • Clean, intuitive UI • Only a small banner ad at the bottom [Recommended for] • Students studying high-school chemistry • Anyone wanting to intuitively understand reactions and molecular structure • Teachers looking for interactive teaching materials • Anyone rediscovering the beauty of chemistry

Collect all 118 elements through daily gacha draws and build your own periodic table. Each element has a rarity based on its atomic number — lighter elements appear more often, while heavy rare elements are harder to find. Upgrade your collection from Normal to Diamond rank as duplicates accumulate. USE YOUR ELEMENTS TO SYNTHESIZE COMPOUNDS Combine collected elements to create 46 compounds, from simple molecules like H₂O and CO₂ to rare noble gas compounds like XeF₂. FEATURES • Daily element gacha with atomic-number-based probability • 118 elements with 5 rank tiers (Normal → Bronze → Silver → Gold → Diamond) • 46 compounds to synthesize • Interactive periodic table with pinch-to-zoom • Daily & weekly missions with bonus gacha rewards • Long-term goals across 10 categories • Login streak tracking with calendar view • Available in Japanese and English A fun way to learn chemistry while enjoying a casual daily game. Perfect for students, educators, and science enthusiasts.
