Verdict

The call

The clearest difference is monetization model: Phyn at free against iAquaLink's free with in-app purchases. Phyn also leads on review sentiment (51% vs 28%) and update cadence (every 3 weeks vs every 2 months). iAquaLink's advantage is ratings volume (101K vs 2.7K) and iOS requirement (13.2 vs 16.0). On price, rating, ads and in-app purchases there is nothing between them.
