Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
ControlMySpa holds the better App Store score, 3.9 against 1.0. That said, the two scores are not equally well evidenced: ControlMySpa has 584 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 11% of ControlMySpa's written reviews are positive against 25% of Master Clear Salt System's, so the app with the better star average is not the one people write more warmly about.
ControlMySpa ships an update every 5 weeks, Master Clear Salt System every 3 weeks. Both last shipped on October 24, 2026.
