CoastWarn monitors official NOAA water-level data and alerts you when observed levels reach the threshold you set. If you live, work, or keep a boat on the coast, you know the drill: nuisance flooding that soaks your car, a dock line that needs more slack, a driveway that disappears at high tide. CoastWarn helps you keep track of the water levels that matter to you. HOW IT WORKS - Find a supported NOAA station using your ZIP code or the station map. - Set the water-level threshold that matters to your property or boat. - Receive flood alerts and all-clear notifications, with current readings and trends. - See “Flood Expected” notices when supported regional forecasts predict your threshold will be reached. BUILT FOR COASTAL REALITY - Official NOAA CO-OPS water-level observations and tide predictions. - Adjustable alert thresholds at eligible stations. - Time-sensitive notifications for minor-or-higher flood alerts, subject to your iPhone’s notification settings. - Tide charts and regional model projections where available. - Alert history, monitoring status, and notices when monitoring is interrupted. WHO IT’S FOR Waterfront homeowners · boaters and marina tenants · coastal businesses · anyone who lives with a rising tide TRY IT FREE CoastWarn is free for 7 days.

Verdict

The call

The clearest difference is update cadence: CoastWarn at every 6 days against Ambient Weather Network's every 2 months. CoastWarn also leads on rating (5.0 vs 4.6). Ambient Weather Network's advantage is ratings volume (14K vs 1) and chart position (#59 vs unranked). On price, ads, in-app purchases and monetization model there is nothing between them.
