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 clearest difference is review sentiment: Computational Complexity at 100% against GeeksforGeeks's 32%. Computational Complexity also leads on rating (5.0 vs 4.0) and in-app purchases (none vs 41). GeeksforGeeks's advantage is update cadence (monthly vs every 3 months) and ratings volume (29 vs 4). On price, ads and device support 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. GeeksforGeeks sells 38 one-off in-app purchases. Computational Complexity asks for nothing beyond the download.
Computational Complexity holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: GeeksforGeeks has 29 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 32% of GeeksforGeeks's.
Computational Complexity ships an update every 3 months, GeeksforGeeks monthly. The most recent releases landed on September 21, 2026 and October 14, 2026 respectively.
