Verdict
The clearest difference is rating: SmartThermal at 5.0 against Thermal P2's 2.1. SmartThermal also leads on monetization model (free vs paid). Thermal P2's advantage is ratings volume (27 vs 1) and update cadence (fortnightly vs every 6 weeks). On price, review sentiment, ads and in-app purchases there is nothing between them.

SmartThermal holds the better App Store score, 5.0 against 2.1. That said, the two scores are not equally well evidenced: Thermal P2 has 27 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 11% of Thermal P2'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, Thermal P2 fortnightly. The most recent releases landed on June 7, 2026 and September 16, 2026 respectively.
