# SmartESS vs SController2.0

The clearest difference is review sentiment: SController2.0 at 100% against SmartESS's 20%. SController2.0 also leads on update cadence (daily vs monthly). SmartESS's advantage is rating (2.7 vs 1.0) and ratings volume (125 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.

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

SmartESS holds the better App Store score, 2.7 against 1.0. 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 100% of SController2.0's, so the app with the better star average is not the one people write more warmly about.

SmartESS ships an update monthly, SController2.0 daily. The most recent releases landed on October 13, 2026 and October 7, 2026 respectively.
