# iSense Mobile vs ArcAir

The clearest difference is review sentiment: ArcAir at 100% against iSense Mobile's 0%. ArcAir also leads on ratings volume (8 vs 1). iSense Mobile's advantage is rating (5.0 vs 4.0) and in-app purchases (none vs 2). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. ArcAir sells 2 one-off in-app purchases. iSense Mobile asks for nothing beyond the download.

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.

iSense Mobile ships an update fortnightly, ArcAir every 5 months. The most recent releases landed on October 19, 2026 and October 24, 2026 respectively.
