Description
VisiGrab is your interactive DSA visualizer — the easiest way to master algorithms and data structures through step-by-step visual animations. Whether you're a computer science student preparing for campus placement, a self-taught developer getting ready for tech interviews, or an experienced programmer brushing up on DSA concepts, VisiGrab makes learning algorithms intuitive and engaging.
๐ Why VisiGrab?
Traditional ways of studying algorithms — textbooks, lectures, and video tutorials — often make it hard to truly understand how an algorithm works step by step. VisiGrab solves this by letting you watch each algorithm execute visually, interact with the data, and build deep understanding through hands-on exploration. Learn at your own pace, not at the speed of a video.
๐ Comprehensive DSA Coverage
Data Structures: • Array • Linked List • Doubly Linked List • Stack • Queue • Hash Table (chaining technique) • Binary Search Tree (BST) • AVL Tree • Red-Black Tree • Trie • Graph
Tree Traversals: • Pre-order traversal • In-order traversal • Post-order traversal • Breadth-first traversal (BFS) • Inserting and deleting nodes in BST • Inserting and deleting nodes in AVL and Red-Black Trees
Graph Algorithms: • Depth-first search (DFS) • Breadth-first search (BFS) • Dijkstra's algorithm (shortest path) • Bellman-Ford algorithm • Minimum Spanning Tree — Prim's algorithm • Minimum Spanning Tree — Kruskal's algorithm • Topological Sort • Union-Find • Graph Constructor — build and visualize your own graphs
Hash Table Operations: • Inserting data into a hash table • Deleting data from a hash table
๐ป Code Examples in Java, Python, and C++
Every algorithm visualization is accompanied by its implementation code in Java, Python, and C++. See the direct link between the code and the visual animation — understand not just what the algorithm does, but how the code makes it happen. Full source code available on GitHub.
๐ 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.
๐ฏ 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 algorithms and go into your interview with confidence. Ideal for LeetCode practice, competitive programming preparation, and CS exam study.
๐ฎ Gamified Learning Experience
VisiGrab features a gaming-inspired design that makes studying algorithms fun and motivating. Interactive controls let you step through each algorithm at your own pace, manipulate data in real-time, and see results instantly.
โจ Key Features
• Interactive visual animations for every algorithm and data structure • Step-by-step execution — pause, rewind, and control the pace • Code view with Java, Python, and C++ implementations • Offline access — study anywhere, no internet required • Gamified interface that keeps you engaged • Comprehensive coverage from basic to advanced DSA topics • One-time purchase — no subscriptions, no ads, no recurring fees • Perfect study companion for CS courses, coding interviews, and competitive programming

Comments on VisiGrab: Algorithms & DSA for Android
โ โ โ โ โ James Sentilecesยท Jan 12, 2025
It's probably the best application I have as a CS Student. If you can, please add some visualization of programming techniques such as Sliding Window, DP, etc.
I liked your app, explanation and bought the total access and started learning dsa through your app and studied till linked lists. Great visual explanation and the corresponding code for the implementation provided in Java and python. I have found that you didn't mention" prev" variable for reverse traversal in the double ended linked list. Doubly linked list explanation can be more detailed. Ps: I confused double-ended linked list with doubly linked list. Hence the above comment. Thank you.

Perfect app for DSA beginners! The diagrams and simple explanations make complex concepts easy to understand. Visual learning at its best - helped me grasp DSA concepts quickly. Highly recommend โญโญโญโญโญ

App is paid. You can only study Array and Linked list for free. Rest us paid.

A lot of crucial parts of algorithms are hidden or skipped, in result students would get wrong understanding of those lessons.

U asking for money for all the things for which I downloaded this app, not worth it
โ โโโโAndrzej Milejkoยท Sep 15, 2025
Only few basic structures and algorithms are accessible. They want money for copy pasted texts. I would recommend books by Sedgwick or Lahore instead. This will be more efficient
