The Free RSVP Tool for London Fitness Groups
Stop juggling spreadsheets and WhatsApp groups. Who's In lets you manage RSVPs, track attendance, and build your fitness community across London—completely free.
London's fitness scene thrives on community—from early-morning runs in Regent's Park and Hampstead Heath to bootcamps in East London's markets and yoga circles in South London neighbourhoods. Whether you're organising casual joggers in Clapham, CrossFit sessions in Shoreditch, or weekend cycling groups across the Thames, keeping members engaged and coordinated across zones is challenging. Who's In is built for London organisers managing diverse, distributed fitness communities.
Challenges London fitness organisers face
No-show Rates Kill Momentum
Without confirmed RSVPs, you never know if 5 or 50 people will show up to your fitness session.
Scattered Communication Channels
Managing fitness groups across WhatsApp, Facebook, and texts wastes time and loses members' contact details.
Hard to Scale Across London
As your fitness community grows across multiple neighbourhoods and session types, tracking who attends what becomes chaotic.
