Heat & Work is an educative application in support to a high-school or university course of thermodynamics. It contains not only a memorandum of the basic equations, but it also contains several animations illustrating the various concepts of thermodynamics. More than 45 screens of thermodynamics! For teachers !! Connect your iPad with a video projector and show the animations to your students in classroom. List of covered subjects: Basic concepts: Definitions, Properties of substances and ideal gases. First law of thermodynamics: Work, Heat transfer and flow application. Second law of thermodynamics: Heat engines, Refrigerators, entropy, Carnot cycle. Application: Rankine cycles, Ideal refrigerator cycle, Otto cycle and Diesel cycle. Each section contains at least one animation or illustration.
Computational Complexity
Explore fundamental concepts of computational complexity with interactive graphs and live sorting algorithm demonstrations. Developed by academics, this app offers a fun and educational way to visualize algorithmic growth and efficiency.
- Interactive Big-O function graphs
- Live sorting algorithm demonstrations
- Visualizes algorithmic growth
- Source code available on Github
- Educational tool for computer science

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 price: Computational Complexity at Free against Heat & Work's $2.99. Computational Complexity also leads on review sentiment (100% vs 67%) and update cadence (every 3 months vs every 14 months). On rating, ads, in-app purchases 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
Computational Complexity is free to download; Heat & Work costs $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.
On the App Store both sit at effectively the same score — 5.0 for Heat & Work against 5.0 for Computational Complexity. Both are backed by a comparable volume of ratings — 1 and 4 respectively. Written reviews are what separate them: 67% of Heat & Work's written reviews are positive against 100% of Computational Complexity's.
Heat & Work ships an update every 14 months, Computational Complexity every 3 months. The most recent releases landed on September 15, 2026 and June 5, 2026 respectively.
