Verdict
The clearest difference is rating: iAquaLink at 4.7 against EOS Spa Control's 1.0. iAquaLink also leads on ratings volume (100K vs 3) and iOS requirement (13.2 vs 15.1). EOS Spa Control's advantage is monetization model (free vs free with in-app purchases). On price, review sentiment, update cadence and ads there is nothing between them.
