ReceptionRating · Positive reviews · Number of ratings

iSense Mobile holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: ArcAir has 8 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of iSense Mobile's written reviews are positive against 100% of ArcAir's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

iSense Mobile ships an update fortnightly, ArcAir every 5 months. The most recent releases landed on June 11, 2026 and September 20, 2026 respectively.
