ReceptionRating · Positive reviews · Number of ratings

IR master holds the better App Store score, 3.7 against 2.5. That said, the two scores are not equally well evidenced: Thermal Master has 15 ratings behind it against 3, so its average is the more settled of the two. 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.

UpkeepUpdate frequency

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.
