# Flir One vs Night Vision Thermal Camera

The clearest difference is rating: Flir One at 4.6 against Night Vision Thermal Camera's 3.7. Night Vision Thermal Camera's advantage is review sentiment (62% vs 22%) and ratings volume (24K vs 7.6K). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Flir One sells 1 in-app purchase, starting at $29.99 per year and Night Vision Thermal Camera sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Flir One holds the better App Store score, 4.6 against 3.7. Both are backed by a comparable volume of ratings — 7.6K and 24K respectively. Written reviews complicate that: 22% of Flir One's written reviews are positive against 62% of Night Vision Thermal Camera'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, Night Vision Thermal Camera monthly. Both last shipped on November 11, 2026.
