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!
