# Heat & Work vs Computational Complexity

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.

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.
