About
Tide Alert is a comprehensive coastal planning application that draws on NOAA tide data from over 3,000 stations covering all major US coastal regions — Atlantic, Pacific, Gulf of Mexico, Great Lakes, Alaska, and Hawaii. Whether you're fishing at dawn, launching a kayak, surfing, or hiking tidal shorelines, the app delivers the accurate, up-to-date predictions you need to stay safe and maximize your time on the water. The app features beautiful iPhone home screen and lock screen tide widgets, Apple Watch complications, and full iPad and Mac support. Smart custom alerts can be set for high tide, low tide, or any specific tide level, making it invaluable for boat access, fishing window planning, and coastal safety. A 10-day swell forecast paired with wind speed, air temperature, and water temperature data helps users plan activities well in advance. Offline mode lets you browse full monthly tide tables and charts without any internet connection — critical for remote coastlines. An integrated solunar calendar adds moon phase tracking alongside sunrise, sunset, moonrise, and moonset times for precision fishing planning. Expert tide guides covering beach safety, boating, surfing, and trip planning are also built into the app. Tide Alert is available as a freemium app with a subscription unlocking advanced widgets, alerts, and forecast features.
