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.
Lennox Smart Tech holds the better App Store score, 4.5 against 4.2. That said, the two scores are not equally well evidenced: Lennox Smart Tech has 60 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 100% of Azure ECM's written reviews are positive against 0% of Lennox Smart Tech's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on June 1, 2026 and August 15, 2026 respectively.
