Verdict

The call

The clearest difference is rating: Carrier SmartHome at 3.5 against Ion Blue's 2.0. Carrier SmartHome also leads on ratings volume (2.6K vs 8) and update cadence (fortnightly vs every 2 months). Ion Blue's advantage is review sentiment (25% vs 11%). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Carrier SmartHome holds the better App Store score, 3.5 against 2.0. That said, the two scores are not equally well evidenced: Carrier SmartHome has 2.6K ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 25% of Ion Blue'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

Ion Blue ships an update every 2 months, Carrier SmartHome fortnightly. The most recent releases landed on November 3, 2026 and November 7, 2026 respectively.
