Verdict
The clearest difference is review sentiment: Tide Graph Pro at 84% against Coastal Explorer's 11%. Tide Graph Pro also leads on rating (4.8 vs 2.8) and ratings volume (3.6K vs 16). Coastal Explorer's advantage is price (Free vs $5.99) and update cadence (every 2 weeks vs every 3 weeks). On ads, in-app purchases and device support there is nothing between them.
