Roll Call: Whos In is a social networking app developed by Chief Tech LLC for iPhone users. It serves as an activity hub for friends, revolutionizing group chats and event organization. Say goodbye to cluttered group chats with Roll Call, as it keeps discussions specific to each activity invitation. Each event has its dedicated chat, user list, and essential details like time and location.

Effortless invitations are at the core of Roll Call. Friends can subscribe to your activities, streamlining the invitation process. When sending an invitation, you already have a list of interested friends, eliminating the need for individual messages. Stay organized by tracking all your upcoming commitments in one place and seamlessly adding activity details to your calendar.
