# HVACsim vs Deckhand!

The clearest difference is rating: Deckhand! at 5.0 against HVACsim's 2.6. HVACsim's advantage is ratings volume (10 vs 1) and iOS requirement (13.4 vs 15.1). 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 Deckhand! sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Deckhand! 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.
