AlgoViewer helps you understand algorithms the way they were meant to be understood — by watching them work, step by step. Whether you're a CS student studying for exams, a developer preparing for technical interviews, or just someone curious about how sorting, searching, and graph traversal actually work, this app breaks it down visually so it clicks. WHAT'S INSIDE 40 algorithms and data structures across 6 categories: • Search — Linear, Binary, Interpolation, Jump, Exponential • Sorting — Bubble, Selection, Insertion, Merge, Quick, Heap, Shell, Counting, Radix • Linear Data Structures — Stack, Queue, Deque, Linked List, Doubly Linked List, Circular Linked List • Non-Linear Data Structures — Binary Tree, Binary Search Tree, AVL Tree, Heap, Hash Table • Graphs — BFS, DFS, Dijkstra, Prim, Kruskal, Bellman-Ford, Floyd-Warshall • Math — Factorial, Fibonacci, GCD, LCM, Sieve of Eratosthenes, Prime Factorization, Fast Exponentiation, Catalan Numbers • Home Screen and Lock Screen widgets: a new Algorithm of the Day every day, plus your streak and progress. HOW IT WORKS 1. Pick an algorithm 2. Enter your own data or use random values 3. Tap play and watch each step unfold with color-coded animations 4. Read the explanation to understand the "why" behind each step 5. Check out the code — every algorithm includes examples in Swift, Python, and Java BUILT FOR LEARNING • Step-by-step animations you can pause, step through, and speed up • Detailed explanations with complexity analysis and real-world use cases • Code examples in 3 languages with copy support • Time complexity charts so you can see how algorithms scale • Quizzes for every algorithm to test what you learned • Your progress, achievements, and favorites sync with iCloud • Light and dark mode • Available in English and Spanish FREE TO START, ONE-TIME UNLOCK 17 algorithms are free, forever. Unlock all 40 with a single one-time purchase: no subscriptions and no ads. Built with care by a developer who believes the best way to learn an algorithm is to see it in action.

Verdict
The clearest difference is update cadence: Biochemistry+ at every 2 weeks against Algo Viewer's every 6 weeks. Biochemistry+ also leads on iOS requirement (17.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Biochemistry+ sells 6 in-app purchases, starting at $7.99 per 7 days and Algo Viewer sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Biochemistry+ ships an update every 2 weeks, Algo Viewer every 6 weeks. The most recent releases landed on October 30, 2026 and October 31, 2026 respectively.
