# HVACsim vs ACLogics

The clearest difference is rating: ACLogics at 5.0 against HVACsim's 2.2. ACLogics also leads on update cadence (every 9 days vs every 2 months). HVACsim's advantage is ratings volume (13 vs 1) and iOS requirement (13.4 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. HVACsim sells 1 one-off in-app purchase and ACLogics sells 3 in-app purchases, starting at $14.99 per month. Whichever you choose, the download price is not the number that matters.

ACLogics holds the better App Store score, 5.0 against 2.2. That said, the two scores are not equally well evidenced: HVACsim has 13 ratings behind it against 1, so its average is the more settled of the two.

HVACsim ships an update every 2 months, ACLogics every 9 days. The most recent releases landed on October 24, 2026 and October 26, 2026 respectively.
