SmarTemp 3.0 holds the better App Store score, 3.3 against 2.6. That said, the two scores are not equally well evidenced: Epoch Li has 70 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 18% of SmarTemp 3.0's written reviews are positive against 29% of Epoch Li's, so the app with the better star average is not the one people write more warmly about.
SmarTemp 3.0 ships an update every 5 weeks, Epoch Li every 3 weeks. The most recent releases landed on October 29, 2026 and October 24, 2026 respectively.
