# D1® SpaIQ vs Control4

The clearest difference is rating: Control4 at 3.5 against D1® SpaIQ's 1.0. Control4 also leads on ratings volume (72 vs 1) and update cadence (fortnightly vs every 2 months). D1® SpaIQ's advantage is review sentiment (50% vs 38%) and iOS requirement (15.0 vs 18.0). 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.

Control4 holds the better App Store score, 3.5 against 1.0. That said, the two scores are not equally well evidenced: Control4 has 72 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of D1® SpaIQ's written reviews are positive against 38% of Control4's, so the app with the better star average is not the one people write more warmly about.

D1® SpaIQ ships an update every 2 months, Control4 fortnightly. The most recent releases landed on October 20, 2026 and October 21, 2026 respectively.
