# Sub vs Control4

The clearest difference is rating: Sub at 4.4 against Control4's 3.6. Sub also leads on ratings volume (778 vs 70) and iOS requirement (15.5 vs 18.0). Control4's advantage is review sentiment (39% vs 15%) and update cadence (fortnightly vs every 5 weeks). On price, ads, in-app purchases and device support there is nothing between them.

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

Sub holds the better App Store score, 4.4 against 3.6. That said, the two scores are not equally well evidenced: Sub has 778 ratings behind it against 70, so its average is the more settled of the two. Written reviews complicate that: 15% of Sub's written reviews are positive against 39% of Control4's, so the app with the better star average is not the one people write more warmly about.

Sub ships an update every 5 weeks, Control4 fortnightly. The most recent releases landed on September 26, 2026 and September 25, 2026 respectively.
