# Matrix Operations vs Thermonator Thermodynamics

The clearest difference is ads: Thermonator Thermodynamics at none against Matrix Operations's shown. Thermonator Thermodynamics also leads on rating (5.0 vs 4.7). Matrix Operations's advantage is ratings volume (19 vs 1). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Matrix Operations sells 1 one-off in-app purchase and Thermonator Thermodynamics sells 6 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Thermonator Thermodynamics holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Matrix Operations has 19 ratings behind it against 1, so its average is the more settled of the two.

Matrix Operations ships an update every 10 days, Thermonator Thermodynamics every 3 weeks. The most recent releases landed on November 3, 2026 and November 5, 2026 respectively.
