# Flir One vs Thermal Camera Filter App

The clearest difference is ratings volume: Flir One at 7.6K against Thermal Camera Filter App's 261. Flir One also leads on rating (4.6 vs 4.4). Thermal Camera Filter App's advantage is iOS requirement (15.0 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 and Thermal Camera Filter App sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Flir One holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Flir One has 7.6K ratings behind it against 261, so its average is the more settled of the two. Written reviews complicate that: 21% of Flir One's written reviews are positive against 27% of Thermal Camera Filter App's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 5 weeks. The most recent releases landed on October 20, 2026 and October 18, 2026 respectively.
