Spider's Thread vs Vektoris3D

Improve your Japanese reading skills with Ryūnosuke Akutagawa's masterpiece, 'The Spider's Thread' (Kumo no Ito). This app offers a side-by-side bilingual reading experience in Japanese and English, designed to help you acquire advanced vocabulary and understand authentic literary grammar in context. Follow the gripping tale of Kandata, a wicked sinner suffering in Hell, who is offered a single chance at salvation when the Buddha lowers a fragile spider's thread from Paradise. Ideal for intermediate to advanced learners (JLPT N3-N2), this app bridges the gap between textbooks and native literature with built-in furigana, romaji, and interactive reading aids.

The well-known solid geometry software Vektoris3D has now been rewritten for learning on iPad and iPhone. Vektoris3D is the app for analytic 3D geometry: for constructing, modifying, exploring, and understanding mathematical models in space. Create points, vectors, lines, planes, surfaces, solids, and measurements in an interactive 3D scene. Change coordinates and variables with sliders and instantly see dependent objects update live. Vektoris3D helps you build models and spatial understanding by connecting mathematical representation, spatial visualization, and construction logic. It shows you not only results, but also relationships, formulas, measurements, and object dependencies. Vektoris3D gives you: - interactive 3D geometry for iPad and iPhone - direct exploration of variables and parameters with sliders - dependency diagrams for traceable construction paths - measurements for distances, angles, areas, and volumes - formula rendering with mathematically precise notation - example and classroom scenes for typical solid geometry topics - an AR view for additional spatial visualization Vektoris3D brings mathematics, model building, and spatial thinking together. This makes mathematical relationships visible, editable, and understandable for you.
