# SmartESS vs Solar App

The clearest difference is rating: Solar App at 3.1 against SmartESS's 2.7. SmartESS's advantage is review sentiment (20% vs 0%) and ratings volume (125 vs 14). 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.

Solar App holds the better App Store score, 3.1 against 2.7. That said, the two scores are not equally well evidenced: SmartESS has 125 ratings behind it against 14, 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 Solar App's, so the app with the better star average is not the one people write more warmly about.

SmartESS ships an update monthly, Solar App every 3 weeks. The most recent releases landed on September 7, 2026 and June 4, 2026 respectively.
