VisiGrab is your interactive DSA visualizer — the easiest way to master Python coding, Java, and C++ programming through step-by-step visual animations. Whether you're a computer science student preparing for a code study exam, a self-taught developer getting ready for tech interviews, or an experienced programmer brushing up on data structures, VisiGrab makes learning intuitive and engaging. Why VisiGrab? The true value of VisiGrab isn’t just the content itself—which you can find online for free—but the way you experience and process it. Studying data structures from raw sources often feels like wandering blindly through a dark cave. VisiGrab acts as your guide, taking you by the hand and leading you smoothly along the winding paths into the light. It is also the ultimate tool to overcome imposter syndrome. Many talented programmers feel like frauds simply because they lack a formal background in algorithms. VisiGrab cures this anxiety by making core computer science concepts so intuitive that they finally click. As a student or developer, you have a choice: waste weeks digging through tons of unstructured tutorials, or build a rock-solid computer science foundation in just a few days. Time is your most valuable resource, and this study app is designed to save it. By delivering content in an adapted, step-by-step sequence, VisiGrab builds a cohesive mental map in your mind, transforming you into a confident engineer. Comprehensive DSA Coverage Data Structures: • Array, Linked List, Doubly Linked List • Stack, Queue • Min-Heap • Hash Table (chaining & open addressing techniques) • Binary Search Tree (BST) & Trie • AVL Tree & Red-Black Tree • B-Tree • Graph & Graph Constructor (build your own graphs) Sorting & Operations: • Bubble, Selection, Insertion, Merge, Heap, Quick Sort • Pre-order, In-order, Post-order, and Breadth-first traversal (BFS) • Inserting and deleting nodes in BST, AVL, and Red-Black Trees • Depth-first search (DFS) & Dijkstra's algorithm (shortest path) • Bellman-Ford, Prim's, and Kruskal's Minimum Spanning Tree • Topological Sort & Union-Find Code Examples in Java, Python, and C++ Every visual DSA animation is accompanied by its implementation code in Java app format, Python coding, and C++. See the direct link between the code and the visual animation — understand not just what the concept does, but how the program makes it happen. Full source code available on GitHub. Available in 10 Languages VisiGrab supports English, German, French, Spanish, Portuguese, Polish, Ukrainian, Japanese, Korean, and Chinese (Simplified) — making it accessible to CS students worldwide. Perfect for Coding Interview Preparation Preparing for your next technical interview at a top tech company? VisiGrab helps you visualize and understand the DSA topics most commonly asked in coding interviews. Build a strong foundation in data structures and go into your interview with confidence. Ideal for LeetCode practice, competitive programming preparation, and CS exam study. Gamified Learning Experience VisiGrab features a gaming-inspired design that makes studying coding fun and motivating. Interactive controls let you step through each node at your own pace, manipulate data in real-time, and see results instantly. Key Features • Interactive visual animations for every binary tree, graph, and structure • Step-by-step execution — pause, rewind, and control the pace • Code view with Java, Python, and C++ implementations • Offline access — study app anywhere, no internet required • Gamified interface that keeps you engaged • One-time purchase — no subscriptions, no ads, no recurring fees Learn DSA Anytime, Anywhere Whether you're commuting, waiting between classes, or studying at home, VisiGrab turns your phone into a powerful code learning study app. No internet connection needed — your complete DSA course is always available offline.

Chess Academy doesn't just let you PLAY chess — it TEACHES it. After every move, it tells you what was right, what was wrong, and WHY, at a level that fits you. How it works • You make your move in a puzzle. • A strong chess engine (Stockfish) decides, with 100% certainty, whether the move is correct. • An AI explains that decision in clear, simple language — never harsh, always teaching. Why it's different • The engine decides, the AI explains: so the explanations come from real analysis, not guesswork. • A path from easy to hard: start with how the pieces move, then forks, pins, and mating patterns. • Invisible adaptive difficulty: your level quietly adjusts on every right or wrong answer, so you progress without getting bored. • Premium is ad-free; in the free version, ads stay OUT of the learning screens. • Solve offline: puzzles live on your device; only the AI explanation needs the internet. Who it's for Everyone aged 8 and up — from someone who just learned the moves to an experienced player sharpening tactics. With Premium: an ad-free experience, unlimited explanations, more detailed coaching, and the ability to ask "why?". Puzzle data is from the Lichess open database (CC0). Premium is an auto-renewable subscription (monthly or yearly). Payment is charged to your Apple Account at purchase confirmation. The subscription renews automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel anytime in Settings › Apple Account › Subscriptions.
