ReceptionRating · Positive reviews · Number of ratings

Renogy holds the better App Store score, 3.8 against 2.6. That said, the two scores are not equally well evidenced: Renogy has 828 ratings behind it against 70, so its average is the more settled of the two. Written reviews complicate that: 11% of Renogy'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.

UpkeepUpdate frequency

Renogy ships an update every 2 weeks, Epoch Li every 3 weeks. The most recent releases landed on November 7, 2026 and November 3, 2026 respectively.
