# SmartESS vs BYD Energy

The clearest difference is rating: BYD Energy at 5.0 against SmartESS's 2.7. SmartESS's advantage is ratings volume (129 vs 1) and review sentiment (20% vs 0%). 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.

BYD Energy holds the better App Store score, 5.0 against 2.7. That said, the two scores are not equally well evidenced: SmartESS has 129 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 20% of SmartESS's written reviews are positive against 0% of BYD Energy's, so the app with the better star average is not the one people write more warmly about.

SmartESS ships an update monthly, BYD Energy every 2 months. The most recent releases landed on November 2, 2026 and October 30, 2026 respectively.
