Both are free to download. TopInfrared sells 1 one-off in-app purchase. SmartThermal asks for nothing beyond the download.
SmartThermal holds the better App Store score, 5.0 against 3.5. That said, the two scores are not equally well evidenced: TopInfrared has 48 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 8% of SmartThermal's written reviews are positive against 40% of TopInfrared's, so the app with the better star average is not the one people write more warmly about.
SmartThermal ships an update every 6 weeks, TopInfrared every 3 weeks. The most recent releases landed on June 7, 2026 and September 23, 2026 respectively.
