Features
Read full description

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 call

The clearest difference is review sentiment: Algorithms HQ at 100% against DSA Master's 13%. Algorithms HQ also leads on in-app purchases (none vs 1) and ads (none vs shown). DSA Master's advantage is update cadence (weekly vs every 16 months) and ratings volume (35 vs 1). On price, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

DSA Master holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: DSA Master has 35 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 13% of DSA Master's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Algorithms HQ ships an update every 16 months, DSA Master weekly. The most recent releases landed on September 8, 2026 and September 7, 2026 respectively.
