# INFRARED THERMOMETER vs IR master

The clearest difference is rating: IR master at 2.6 against INFRARED THERMOMETER's 1.7. IR master also leads on update cadence (every 3 months vs every 5 months). INFRARED THERMOMETER's advantage is review sentiment (50% vs 13%) and iOS requirement (8.0 vs 13.0). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

IR master holds the better App Store score, 2.6 against 1.7. Both are backed by a comparable volume of ratings — 12 and 5 respectively. Written reviews complicate that: 50% of INFRARED THERMOMETER's written reviews are positive against 13% of IR master's, so the app with the better star average is not the one people write more warmly about.

INFRARED THERMOMETER ships an update every 5 months, IR master every 3 months. The most recent releases landed on October 24, 2026 and October 27, 2026 respectively.
