# Flir One vs DEPSTECH

The clearest difference is rating: Flir One at 4.6 against DEPSTECH's 2.2. Flir One also leads on ratings volume (7.6K vs 256). DEPSTECH's advantage is in-app purchases (none vs 1) and iOS requirement (11.0 vs 18.0). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Flir One sells 1 in-app purchase, starting at $29.99 per year. DEPSTECH asks for nothing beyond the download.

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.

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.
