# Renogy vs Epoch Li

The clearest difference is rating: Renogy at 3.8 against Epoch Li's 2.6. Renogy also leads on ratings volume (828 vs 70). Epoch Li's advantage is review sentiment (29% vs 11%). On price, update cadence, ads and in-app purchases there is nothing between them.

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

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.

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.
