Verdict
The clearest difference is rating: IR master at 3.7 against Thermal Master's 2.5. Thermal Master's advantage is update cadence (every 3 weeks vs every 3 months) and review sentiment (36% vs 27%). On price, ads, in-app purchases and monetization model there is nothing between them.

IR master holds the better App Store score, 3.7 against 2.5.

Written reviews complicate that: 27% of IR master's written reviews are positive against 36% of Thermal Master's, so the app with the better star average is not the one people write more warmly about.
IR master ships an update every 3 months, Thermal Master every 3 weeks. The most recent releases landed on October 14, 2026 and October 12, 2026 respectively.
