Vektoris3D vs Overwrite

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.

Overwrite is the ultimate minimalist workspace for developers, writers, and students with offline-first LaTeX and Markdown document editing. Ditch the bloat. Overwrite combines a distraction-free environment with high-performance editing tools. Whether you’re drafting notes in Markdown, writing mathematical equations in LaTeX, or testing JavaScript and Dart scripts, Overwrite handles it all natively and 100% offline. Designed to look stunning on both iPhone and iPad, the app features a responsive layout, a customizable monospaced interface, and a custom keyboard accessory bar to make editing on the go effortless. KEY FEATURES: 1. Rich Markdown Workspace (WYSIWYG) Draft beautiful documentation, prose, or journals. Live rendering hides formatting syntax markers unless you are editing the line (Notion-style). Format quickly with an interactive slash command (/) menu and floating selection toolbars. 2. Advanced LaTeX & Math Workspace Render complex math formulas, matrices, and equations instantly (powered offline by MathJax). Tablet Optimization: Work efficiently on iPad with a dual-pane side-by-side view (edit on the left, live preview on the right). Accessory Bar: Type faster using a dedicated keyboard accessory bar for commonly used special symbols (\, { }, \frac, \sqrt, \pi, etc.). Seamlessly wrap selected text inside equations or bracket formats with a single tap. 3. PDF Export & Offline Sync Export your Markdown and LaTeX files directly to PDF with clean, premium typography. Uses high-quality fonts (Inter and Source Code Pro) offline, with online fallback for emoji support (Noto Color Emoji). Auto-save debouncing keeps your drafts synchronized and secure on local storage. 4. Offline Code Editor Edit Java, Javascript, Python or Dart Code complete with full syntax highlighting and auto completion in a VS Code style editor. Unlock your productivity. Simplify your writing and coding workflow with Overwrite.
