# MobIR vs SmartThermal

The clearest difference is rating: SmartThermal at 5.0 against MobIR's 2.2. MobIR's advantage is review sentiment (50% vs 8%) and ratings volume (5 vs 1). On price, update cadence, 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.

SmartThermal holds the better App Store score, 5.0 against 2.2. That said, the two scores are not equally well evidenced: MobIR has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of MobIR's written reviews are positive against 8% of SmartThermal's, so the app with the better star average is not the one people write more warmly about.

MobIR ships an update every 2 months, SmartThermal every 6 weeks. The most recent releases landed on September 10, 2026 and June 7, 2026 respectively.
