Verdict

The call

The clearest difference is rating: TVI Viewer at 5.0 against AirScan's 4.4. TVI Viewer also leads on iOS requirement (6.0 vs 13.0). AirScan's advantage is ratings volume (454 vs 1) and review sentiment (73% vs 50%). On price, update cadence, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

TVI Viewer holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: AirScan has 454 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of TVI Viewer's written reviews are positive against 73% of AirScan's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

TVI Viewer ships an update every 3 months, AirScan every 2 months. The most recent releases landed on October 9, 2026 and October 29, 2026 respectively.
