Mr. Seawatcher

Know before you go.

Mr. Seawatcher transforms marine forecast data into something more useful: a personalized comfort-based rating that helps you quickly decide whether today is a Good, Mixed, or Poor day on the water. Instead of digging through technical charts and multiple weather apps, you get a clear, glanceable view of marine conditions for your selected coastal spot.

Designed for recreational boaters, marina users, anglers, paddlers, surfers, and coastal travelers who want clarity without complexity.

Personalized Marine Evaluation

Set your own comfort thresholds:

• Minimum and maximum wave height
• Preferred swell period
• Maximum wind speed
• Minimum temperature
• Preferred wind direction

Mr. Seawatcher evaluates forecast data against your settings and summarizes conditions into a simple daily rating.

The forecast adapts to you — not the other way around.

Three-Day Snapshot

Quickly review:

• Today
• Tomorrow
• The day after tomorrow

Each day displays:

• Air temperature
• Sky condition
• Wind speed and direction
• Wave height
• Swell period
• Marine advisory status

All presented in a calm, readable interface designed for fast decision-making.

Smart Spot Management

• Save up to four favorite locations
• Swipe horizontally on the home screen to cycle through favorites
• Browse spots by region
• Your selected spot remains the default

Switching between your regular spots is fast and intuitive.

Intelligent Refresh and Caching

Mr. Seawatcher refreshes forecasts automatically when the app opens or when you change spots.

To keep switching fast and reduce unnecessary service calls, the app uses short-term caching for recently viewed locations. Returning to a spot within about an hour reuses the latest forecast instead of fetching again. Live forecast fetches are limited daily to help keep the app sustainable as a simple one-time purchase. Cached revisits do not count toward the limit. If the daily live refresh limit is reached, the most recent forecast remains visible.

Daily Summary Reminder

Enable a daily local notification reminder at your preferred time. The reminder references your currently selected spot and updates automatically if you change locations.

Detailed Forecast View

The Forecast screen provides full condition details for users who want more context, including:

• Exact wind direction
• Detailed marine values
• Advisory visibility

Use it when you want more information than the home cards provide.

Built with Clarity in Mind

Mr. Seawatcher is intentionally simple:

• No navigation tools
• No route planning
• No vessel tracking
• No background tracking

This is a forecast awareness tool designed to help you review conditions quickly and decide when to take a closer look.

Important Notice

Mr. Seawatcher is not a navigation, safety, or emergency tool. Forecast data is model-based and conditions can change quickly. Always consult official marine forecasts, local advisories, charts, and use proper judgment before heading out on the water.

Clean. Personalized. Practical.

Mr. Seawatcher helps you make more confident coastal decisions — faster.
