Algorithm++ vs Sound of Sorting

Unlock the world of algorithms with Algorithm++! Visualize, listen, and master the logic behind sorting algorithms. Whether you are a Computer Science student preparing for exams, a developer brushing up for technical interviews, or an enthusiast who enjoys satisfying visualizations, Algorithm++ is the ultimate educational tool. Visualize & Customize Watch 16 different sorting algorithms in action. Use the dynamic sliders to adjust the sorting speed and change the array size from 10 to 100 items. Experience the difference between O(n²) and O(n log n) visually. Hear the Algorithms (Sonification) Don't just watch—listen! Algorithm++ features a real-time audio oscillator that generates sound based on value comparisons and swaps. Hear the chaotic noise of a random array transform into a satisfying, rising scale as it gets sorted. Inspect the Code Learn how it works under the hood. View the actual Swift source code for every algorithm with beautiful syntax highlighting. Perfect for understanding the implementation details. Master Big O Complexity Get instant access to Time Complexity and Space Complexity data for every algorithm. Understand the efficiency trade-offs between different methods. Test with Real-World Patterns Algorithms behave differently based on input data. Use the "Data Patterns" feature to test sorting on: Random: The standard chaos. Sorted: See how algorithms handle already-sorted data. Reversed: The worst-case scenario for many algorithms. Almost Sorted: Watch Insertion Sort shine! Few Unique: Visualize sorting with repeated values. Included Algorithms: From the basics to the advanced, and even the "joke" sorts: Basic: Bubble, Selection, Insertion Efficient: Quick Sort, Merge Sort, Heap Sort, Shell Sort Educational: Cocktail Shaker, Comb, Odd-Even, Gnome, Cycle, Pancake, Stooge Non-Comparative: Radix Sort (LSD) Bonus: Bogo Sort (Good luck!) Features: Clean, modern SwiftUI interface. Interactive controls (Pause, Resume, Step). Mute/Unmute functionality. Detailed algorithm information cards. Dark Mode support. Download Algorithm++ today and turn abstract concepts into clear, interactive experiences!

Sound of Sorting visualizes 32 classic sorting algorithms with live audio and motion. Every comparison rings a note; every swap redraws a bar. Watch - and listen to - how each algorithm pulls an array from chaos into order. Originally released in 2013 as a C++ demo for university algorithms classes, Sound of Sorting has been viewed tens of millions of times on YouTube. This is the app version: native, fast, and rebuilt for touch and trackpad. WHAT YOU GET • 32 sorting algorithms, from familiar (Bubble, Selection, Insertion) to obscure (Cycle Sort, Smooth Sort, Block Merge Sort) • Real-time audio: every array access plays a tone whose pitch matches the value being read • Colored bars: access highlights, permanent marks, sorted regions — all in live animation • Adjustable array size (8 to 2048 elements) and animation speed • Step mode: advance one comparison at a time • Infinite Play: start a never-ending parade of random sorts • Live stats: comparison count and access count update as the sort runs FREE ALGORITHMS Six foundational sorts included at no cost: • Selection Sort • Insertion Sort • Binary Insertion Sort • Merge Sort (classical recursive) • Merge Sort (iterative) • Quick Sort - Hoare (LR ptrs) FULL COLLECTION — ONE-TIME PURCHASE Unlock the remaining 26 algorithms with a single $1.99 purchase: • More Quick Sorts - Lomuto (LL ptrs), ternary (LR ptrs, LL ptrs) and Dual-Pivot partition schemes • Bubble Sort, Cocktail Shaker Sort, Gnome Sort • Comb Sort • Shell Sort (Ciura gap sequences) • Heap Sort with heap level coloring • Smooth Sort • Odd-Even Sort, Bitonic Sort, Batcher's Odd-Even Merge Sort • Cycle Sort • Radix Sort - LSD and MSD variants • gcc's std::sort and std::stable_sort - the real implementations • Tim Sort • Block Merge Sort • Bogo Sort, Bozo Sort and Stooge Sort, for entertainment • ... and more No subscription. No ads. No analytics. No account. Just algorithms. WHO IT'S FOR • CS students learning how sorts actually compare in practice • Instructors looking for a lecture demo that's easier to launch than running g++ live • Engineers who want to rewatch a Quick Sort partition and finally see why it's fast • Anyone who finds audio-visual algorithm traces calming to watch TECHNICAL NOTES Sound of Sorting runs entirely on-device. It makes no network calls, collects no data, and has no accounts. In-app purchases are processed by Apple. — Timo Bingmann
