This app demonstrates the basic principles of computational complexity. The growth of a few typical Big-O functions are illustrated with an interactive graph, and live demonstrations of sorting algorithms can be run using randomly generated data. This app was developed at SUNY Binghamton, by Prof. Patrick H. Madden. Version 1.1 is an expansion on this, with the assistance a few students (primarily Keith Gardner, and undergrad, and Anthony Canino, an MS grad). We're working on the app as a fun project, and as a way to introduce ACM student group members to iOS programming. The source for the app is available on Github; we'll be adding more algorithms and things, and if you're interested in helping out with the development, let us know! https://github.com/keithgardner2/complexity Yay computational complexity! Yay Hartmanis and Stearns!

Verdict

The call

The clearest difference is review sentiment: Computational Complexity at 100% against DSA Master's 13%. Computational Complexity also leads on rating (5.0 vs 4.2) and in-app purchases (none vs 1). DSA Master's advantage is update cadence (weekly vs every 3 months) and ratings volume (35 vs 4). On price and device support there is nothing between them.

Both are free to download. DSA Master sells 1 one-off in-app purchase. Computational Complexity asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

Computational Complexity holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: DSA Master has 35 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 100% of Computational Complexity's written reviews are positive against 13% of DSA Master's.

UpkeepUpdate frequency

Computational Complexity ships an update every 3 months, DSA Master weekly. The most recent releases landed on September 21, 2026 and October 9, 2026 respectively.
