Seagull COAST

A New Mobile App for Great Lakes Coastal Safety

Seagull Coast is a new mobile application designed to help people make safer decisions when planning recreation in Great Lakes coastal areas.

With a user-centered design process that included workshops with recreational users and domain experts, surveys for requirements gathering, and multiple rounds of low-fidelity and high-fidelity design iterations, the app’s structure is informed by- and built for- the user. 

Seagull Coast offers:

  • Clear, easy-to-understand coastal safety information for recreational planning
  • Identification of unsafe lake conditions that may impact activities such as boating, swimming, paddling, and shoreline recreation
  • A mobile experience designed specifically for on-the-go decision-making
  • Science-based data translated into actionable insights for everyday users

The app was launched in July of 2026. Download and test the free app for yourself!
