# SmartCONTROL WiFi vs DiO one

The clearest difference is rating: SmartCONTROL WiFi at 4.5 against DiO one's 4.0. SmartCONTROL WiFi also leads on ratings volume (422 vs 21) and iOS requirement (12.0 vs 15.0). DiO one's advantage is review sentiment (61% vs 41%). 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.

SmartCONTROL WiFi holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: SmartCONTROL WiFi has 422 ratings behind it against 21, so its average is the more settled of the two. Written reviews complicate that: 41% of SmartCONTROL WiFi's written reviews are positive against 61% of DiO one's, so the app with the better star average is not the one people write more warmly about.

SmartCONTROL WiFi ships an update every 3 months, DiO one every 2 months. The most recent releases landed on September 23, 2026 and July 31, 2026 respectively.
