# Device Detector vs SmartThermal

The clearest difference is rating: SmartThermal at 5.0 against Device Detector's 4.4. SmartThermal also leads on ads (none vs shown) and monetization model (free vs ad-supported). Device Detector's advantage is review sentiment (49% vs 8%) and ratings volume (3.6K vs 1). On price, update cadence, in-app purchases and device support 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 4.4. That said, the two scores are not equally well evidenced: Device Detector has 3.6K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 49% of Device Detector'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.

Device Detector ships an update monthly, SmartThermal every 6 weeks. The most recent releases landed on October 8, 2026 and September 23, 2026 respectively.
