ReceptionRating · Positive reviews · Number of ratings

Flir One holds the better App Store score, 4.6 against 2.2. That said, the two scores are not equally well evidenced: Flir One has 7.6K ratings behind it against 256, so its average is the more settled of the two. Written reviews complicate that: 21% of Flir One's written reviews are positive against 26% of DEPSTECH's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Flir One ships an update every 5 weeks, DEPSTECH every 4 weeks. The most recent releases landed on October 18, 2026 and October 17, 2026 respectively.
