Verdict

The call

The clearest difference is rating: GreenTech Connect at 4.5 against Carrier SmartHome's 3.5. GreenTech Connect also leads on iOS requirement (11.0 vs 15.1). Carrier SmartHome's advantage is update cadence (fortnightly vs every 16 months) and ratings volume (2.6K vs 13). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

GreenTech Connect holds the better App Store score, 4.5 against 3.5. That said, the two scores are not equally well evidenced: Carrier SmartHome has 2.6K ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 0% of GreenTech Connect's written reviews are positive against 11% of Carrier SmartHome's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

GreenTech Connect ships an update every 16 months, Carrier SmartHome fortnightly. The most recent releases landed on November 3, 2026 and November 15, 2026 respectively.
