Verdict
The clearest difference is review sentiment: Boat Beacon at 61% against Coastal Explorer's 11%. Boat Beacon also leads on rating (4.6 vs 2.8) and ratings volume (866 vs 16). Coastal Explorer's advantage is price (Free vs $14.99) and update cadence (every 2 weeks vs every 2 months). On ads, in-app purchases, monetization model and device support there is nothing between them.
