Lexilo vs Vektoris3D

Learn the vocabulary that matters to you. Lexilo turns the words and expressions you encounter while learning into a personal collection that is easy to organize and review. BUILD YOUR OWN VOCABULARY LISTS Create lists for a topic, lesson, trip or personal goal. Save words from a class, book, movie or conversation—anything you want to remember. ADD MEANING AND CONTEXT Store a translation, explanation or usage note. You don't just memorize a word: you learn how to understand and use it. REVIEW EFFECTIVELY Practice with flashcards and dictation. Spaced repetition brings each item back at the right time to strengthen long-term memory. TRAIN YOUR LISTENING Listen at normal or slower speed, type what you hear and check your answer. Corrections include the translation and explanation whenever available. LEARN YOUR WAY • Personal collection of words and expressions • Custom vocabulary lists • Translations, explanations and context • Flashcards and dictation exercises • Spaced repetition • Progress and streak tracking • Multiple learning languages • iCloud sync across your devices Build your vocabulary one list at a time, and review until it feels natural.

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.
