# iAquaLink vs CentroControl

The clearest difference is rating: iAquaLink at 4.7 against CentroControl's 3.8. iAquaLink also leads on in-app purchases (none vs 1) and ratings volume (100K vs 14). CentroControl's advantage is review sentiment (67% vs 28%) and iOS requirement (9.0 vs 13.2). On price, update cadence, ads and monetization model there is nothing between them.

Both are free to download. CentroControl sells 1 one-off in-app purchase. iAquaLink asks for nothing beyond the download.

iAquaLink holds the better App Store score, 4.7 against 3.8. That said, the two scores are not equally well evidenced: iAquaLink has 100K ratings behind it against 14, so its average is the more settled of the two. Written reviews complicate that: 28% of iAquaLink's written reviews are positive against 67% of CentroControl's, so the app with the better star average is not the one people write more warmly about.

iAquaLink ships an update every 2 months, CentroControl every 3 months. The most recent releases landed on September 24, 2026 and June 7, 2026 respectively.
