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 review sentiment: Algorithms HQ at 100% against Little Man Computer's 50%. Algorithms HQ also leads on update cadence (every 16 months vs every 45 months). Little Man Computer's advantage is rating (4.3 vs 4.0) and ratings volume (6 vs 1). On price, ads, in-app purchases and monetization model 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. Neither carries in-app purchases, so what you see is what you pay.
Little Man Computer holds the better App Store score, 4.3 against 4.0. That said, the two scores are not equally well evidenced: Little Man Computer has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Algorithms HQ's written reviews are positive against 50% of Little Man Computer's, so the app with the better star average is not the one people write more warmly about.
Algorithms HQ ships an update every 16 months, Little Man Computer every 45 months. The most recent releases landed on September 8, 2026 and June 10, 2026 respectively.
