# ControlMySpa vs PoolSync

The clearest difference is rating: ControlMySpa at 3.9 against PoolSync's 2.1. ControlMySpa also leads on ratings volume (493 vs 64). PoolSync's advantage is review sentiment (20% vs 11%). 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.

ControlMySpa holds the better App Store score, 3.9 against 2.1. That said, the two scores are not equally well evidenced: ControlMySpa has 493 ratings behind it against 64, so its average is the more settled of the two. Written reviews complicate that: 11% of ControlMySpa's written reviews are positive against 20% of PoolSync'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, PoolSync every 2 months. The most recent releases landed on October 15, 2026 and October 12, 2026 respectively.
