Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

TempPro Sensor holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: TempPro Sensor has 11K ratings behind it against 828, so its average is the more settled of the two. Written reviews complicate that: 79% of AC Infinity's written reviews are positive against 46% of TempPro Sensor's, so the app with the better star average is not the one people write more warmly about.
