# SmartESS vs UCANESS

The clearest difference is ratings volume: SmartESS at 125 against UCANESS's 2. SmartESS also leads on review sentiment (20% vs 0%). UCANESS's advantage is rating (3.0 vs 2.7). 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.

UCANESS holds the better App Store score, 3.0 against 2.7. That said, the two scores are not equally well evidenced: SmartESS has 125 ratings behind it against 2, 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 UCANESS's, so the app with the better star average is not the one people write more warmly about.

SmartESS ships an update monthly, UCANESS every 6 weeks. The most recent releases landed on October 13, 2026 and September 30, 2026 respectively.
