ReceptionRating · Positive reviews · Number of ratings

CozyLife Smart holds the better App Store score, 2.5 against 1.0. That said, the two scores are not equally well evidenced: CozyLife Smart has 171 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 29% of Simon iO's written reviews are positive against 15% of CozyLife Smart's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Simon iO ships an update every 3 months, CozyLife Smart fortnightly. The most recent releases landed on November 10, 2026 and November 7, 2026 respectively.
