This app allows the individual Azure motor speed taps to be adjusted for optimizing system CFM.Azure blower motor adjustments can be made to only one tap at a time; the tap being energized is the tap that can be adjusted. Note: if equipped, a 625RPM constant fan tap is factory locked and cannot be adjusted. For lower speeds, select another tap and reduce torque.

Verdict
The clearest difference is review sentiment: Azure ECM at 100% against Bluon HVAC's 55%. Azure ECM also leads on ads (none vs shown) and monetization model (free vs ad-supported). 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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Bluon HVAC holds the better App Store score, 4.8 against 4.2. 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.
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.
