About this app

Is it safe to go to the mudflats today?

Multtaeya is an app that helps you check tide and weather information at a glance and determine safe activity times when preparing for mudflat experiences, shellfish gathering, clam digging, or coastal trips.

Instead of complex tide tables, quickly check conditions for up to 7 days starting today using the mudflat safety index and color ratings.

Key Features

• Mudflat Safety Index: We synthesize tide, low tide time, wind, wave height, and precipitation information to display a reference score from 0 to 100 along with safety, caution, and danger ratings.

• Today's Optimal Time: We provide easy-to-understand guidance on the best times for activities based on low tide times and surrounding conditions.

• Up to 7-Day Forecast: You can check the expected safety level and weather in advance for dates you plan to experience the mudflats or shellfish gathering.

• Nationwide Beaches & Mudflat Experience Sites: You can find locations near your current position or select a desired spot on the map. • Integrated Tide, Weather, and Information
Check low and high tide times, temperature, precipitation, wind speed, wave height, and sunrise/sunset information all on one screen.

• Nighttime Activity Warning
We provide warnings regarding the dangers of nighttime activities so you do not enter the mudflats after sunset.

• Visit Notifications
Set your destination and time period to receive push notifications for today's mudflat information at 7 AM and tomorrow's at 8 PM.

• Favorites
Save your frequently visited beaches and mudflat experience sites for quick access.

Recommended for:

• Families planning a mudflat experience with children
• Those who enjoy haerujil (sea foraging) and clam digging
• Those curious about tide times while preparing for a trip to an island or coast
• Those who want to check low and high tides and weather all at once

How to Use

Search for the beach or mudflat experience site you want to visit, or select it on the map.

Check the mudflat safety index, optimal time, tide times, and weather for each date.

Set your visit period and receive notifications for necessary tidal flat information.

You can start immediately without signing up.

※ Tidal information is sourced from the Korea Hydrographic and Oceanographic Agency's Public Data Portal, while weather and wave height information is sourced from Open-Meteo.

※ The tidal flat safety index and optimal time are for reference only and do not guarantee activity feasibility or on-site safety. Please check weather advisories, site closures, tidal changes, and local government guidance first, and adhere to safety guidelines.
Before mudflat experiences or sea foraging, check the safety index, tides, weather, and 7-day forecast, and even receive visit notifications.
