Verdict
The clearest difference is price: Bluon HVAC at Free against HVAC Decoder's $9.99. Bluon HVAC also leads on rating (4.8 vs 4.0) and ratings volume (4.5K vs 28). HVAC Decoder's advantage is ads (none vs shown) and review sentiment (69% vs 55%). On in-app purchases, device support and iOS requirement there is nothing between them.

Bluon HVAC is free to download; HVAC Decoder costs $9.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Bluon HVAC holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: Bluon HVAC has 4.5K ratings behind it against 28, so its average is the more settled of the two. Written reviews complicate that: 69% of HVAC Decoder's written reviews are positive against 55% of Bluon HVAC's, so the app with the better star average is not the one people write more warmly about.
HVAC Decoder ships an update every 3 months, Bluon HVAC monthly. The most recent releases landed on September 21, 2026 and September 28, 2026 respectively.
