Bluon HVAC's advantage is rating (4.8 vs 4.2) and ratings volume (4.5K vs 5). On price, in-app purchases and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Bluon HVAC holds the better App Store score, 4.8 against 4.2. That said, the two scores are not equally well evidenced: Bluon HVAC has 4.5K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 55% of Bluon HVAC's written reviews are positive against 100% of Azure ECM's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Bluon HVAC ships an update monthly, Azure ECM every 2 months. The most recent releases landed on September 24, 2026 and June 1, 2026 respectively.
