ReceptionRating · Positive reviews · Number of ratings

PIX4Dcatch holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: PIX4Dcatch has 264 ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 42% of Airdata HD Sync's written reviews are positive against 33% of PIX4Dcatch's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Airdata HD Sync ships an update every 3 weeks, PIX4Dcatch every 2 weeks. The most recent releases landed on September 26, 2026 and October 15, 2026 respectively.
