Verdict
iAquaLink and Gemstone Lights both sit at 4.7 stars, but that hides the real split: 88% of Gemstone Lights's written reviews are positive against 28% of iAquaLink's. Gemstone Lights also leads on monetization model (free vs free with in-app purchases) and update cadence (fortnightly vs every 2 months). iAquaLink's advantage is ratings volume (101K vs 4.6K) and iOS requirement (13.2 vs 15.0). On price, rating, ads and in-app purchases there is nothing between them.
