Verdict

The call

The clearest difference is ratings volume: Carrier SmartHome at 2.6K against Ion SmartHome's 228. On price, rating, review sentiment and update cadence there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

Ion SmartHome holds the better App Store score, 3.7 against 3.5. That said, the two scores are not equally well evidenced: Carrier SmartHome has 2.6K ratings behind it against 228, so its average is the more settled of the two. Written reviews complicate that: 11% of Carrier SmartHome's written reviews are positive against 10% of Ion SmartHome's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on November 7, 2026 and November 8, 2026 respectively.
