Seattle's fitness culture thrives on outdoor activities year-round, from Green Lake running clubs and Discovery Park trail groups to Puget Sound kayaking communities. With rainy winters and mild summers, Seattle fitness organisers need flexible tools that handle weather cancellations, spontaneous route changes, and shifting attendance. Who's In is built for the Pacific Northwest organiser who values community, sustainability, and real-time coordination.

Challenges Seattle fitness organisers face

Tracking Fitness Group Attendance

Knowing who's actually showing up to your runs, classes, or rides is hard without a dedicated tool.

Managing Weather Cancellations

Seattle weather changes fast—you need to notify members quickly when routes or sessions are cancelled or rescheduled.

Coordinating Multiple Sessions

Running beginner and advanced groups, or weekday and weekend events, gets chaotic without a central place to manage them.
