Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Flir One sells 1 in-app purchase, starting at $29.99 per year. DC asks for nothing beyond the download.
Flir One holds the better App Store score, 4.6 against 3.9. That said, the two scores are not equally well evidenced: Flir One has 7.6K ratings behind it against 27, so its average is the more settled of the two. Written reviews complicate that: 21% of Flir One's written reviews are positive against 54% of DC'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, DC every 3 weeks. The most recent releases landed on October 15, 2026 and October 4, 2026 respectively.
