Algonote vs Graphica

AlgoNote helps you truly understand algorithms by seeing them in motion. Instead of memorizing pseudocode, watch each algorithm run step by step with clear, interactive visualizations. Whether you are preparing for coding tests and technical interviews, studying computer science, or refreshing the fundamentals as a working engineer, AlgoNote turns abstract concepts into intuitive visuals you can follow at your own pace. WHAT YOU CAN DO - Watch algorithms execute step by step with smooth animations - Follow the running code in sync with each visualization - Compare how different algorithms solve the same problem, side by side - Read concise concept explanations that build real intuition - Replay any step as many times as you need, at your own pace TOPICS COVERED - Sorting: bubble, selection, insertion, merge, quick, and more - Searching: linear and binary search - Graphs: BFS, DFS, and shortest paths - Trees and traversals - Dynamic programming - More topics added over time WHO IT IS FOR - Job seekers preparing for coding tests and technical interviews - Students learning data structures and algorithms - Developers who want to refresh the fundamentals AlgoNote is free to use. Optional rewarded ads let you earn points to unlock additional learning content. Start seeing algorithms, not just reading about them.

Graphica turns abstract graph theory into something you can actually see. Build your own graphs or load sample ones, then watch nine classic algorithms run step by step — from breadth-first and depth-first search to Dijkstra's shortest path and minimum spanning tree algorithms like Kruskal's and Prim's. FEATURES • 9 graph algorithms, visualized step by step • Pinch-to-zoom canvas for graphs of any size • Synchronized pseudocode panel — see exactly which line is executing • Ready-made sample graphs to explore immediately • Build and edit your own custom graphs • Fully native SwiftUI, built for iOS PRIVACY FIRST Graphica works completely offline. No account, no ads, no analytics, no tracking — your data never leaves your device. Whether you're a computer science student preparing for exams, a developer brushing up before technical interviews, or simply curious how these algorithms work, Graphica makes graph theory click.
