About this APK

VisiGrab: Learn to Code & DSA is an app by Ievgen Ovsii in the Education category, listed since at least March 2021. It includes native code only for ARM 64-bit, so it won't install on phones that can only run 32-bit apps.

Since version 1.13.6, the APK grew from 33.9 MB to 96.9 MB and the minimum Android version rose from 5.1 to 7.0. It asks for 6 permissions, none of them sensitive. It asks for the same permissions as version 1.25.0. The app offers in-app purchases through Google Play.

What's new in v1.26.0

• Added B-Tree — add and remove keys, choose the maximum degree, and watch the nodes split, borrow and merge

Description

From the listing uploaded by “appupdater”.

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 • 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.
