# HVACsim vs ScanPlan

The clearest difference is rating: ScanPlan at 5.0 against HVACsim's 2.6. ScanPlan also leads on update cadence (every 5 days vs every 2 months). HVACsim's advantage is ratings volume (10 vs 1) and iOS requirement (13.4 vs 26.0). 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 ScanPlan sells 3 in-app purchases, starting at $19.99 per year. Whichever you choose, the download price is not the number that matters.

ScanPlan holds the better App Store score, 5.0 against 2.6. That said, the two scores are not equally well evidenced: HVACsim has 10 ratings behind it against 1, so its average is the more settled of the two.

HVACsim ships an update every 2 months, ScanPlan every 5 days. The most recent releases landed on October 7, 2026 and October 19, 2026 respectively.
