A fun and didactic app to learn computer science algorithms! See how algorithms are working by watching an animation of their execution. Understand how data is manipulated as it is animated through an intuitive representation of its contents. Always know which line is executed in the pseudo-code, what are the values of the variables. Need to quickly refresh your memory? Just use the app as a quick reference on the main characteristics of each algorithm! Main features: - Execute a single instruction, or undo the previous one - Run, or rewind the algorithm until you decide to pause the execution - Adjust the speed of the animation - Best and worst case input data for sorting algorithms - Change the input data: size (up to 500), maximum value or data distribution (random, sorted, many duplicates, etc.) - For data structures, choose the next function to execute, or let a scenario choose for you, so you can see how the data structure evolves. - Landscape or portrait orientation This version contains the following algorithms: Linear Data Structures: - Linked Lists, including a view on memory - Queue - Stack Sorting algorithms: - Bubble Sort - Cocktail Sort - Gnome Sort - Insertion Sort - Quick Sort - Selection Sort More algorithms and more features are on the way!

Verdict
The clearest difference is rating: Algorithm Visualizer at 5.0 against Algorithms HQ's 4.0. Algorithm Visualizer also leads on update cadence (every 9 days vs every 16 months) and ratings volume (4 vs 1). Algorithms HQ's advantage is in-app purchases (none vs 3). On price, review sentiment, ads and iOS requirement 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. Algorithm Visualizer sells 3 one-off in-app purchases. Algorithms HQ asks for nothing beyond the download.
Algorithm Visualizer holds the better App Store score, 5.0 against 4.0. Both are backed by a comparable volume of ratings — 1 and 4 respectively. Written reviews split almost evenly too, at 100% and 100% positive.
Algorithms HQ ships an update every 16 months, Algorithm Visualizer every 9 days. The most recent releases landed on September 8, 2026 and June 4, 2026 respectively.
