Who's In — for Organizers
Roster, invites & RSVPs
Only for iPhone
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
iPhone
Run your group, not the group chat. Build a roster from contacts, send a two-tap invite, and see who's actually coming. Private by design, cloud optional.
Who's In makes it easy to organize any recurring group — pickup volleyball, book club, poker night, fishing crew.
Build a roster from your contacts. Rate everyone on reliability, skill, and vibe. Send a prefilled group-text invite in two taps. Then tap In / Maybe / Out as replies land.
ACTIVITY INSIGHTS (Pro)
After three sessions, see your group's fill rate, response breakdown, and player rankings by acceptance rate. MVP, fastest/slowest replier, and most drops — all surfaced automatically.
ROSTER
Import from Contacts. Rate players and sort by acceptance, skill, vibe, name, or most recently invited. Away/paused players with optional return dates (Pro).
INVITE
Generates a prefilled message ready to send via Messages. Need more people? Invite a second round from inside the active session without starting over.
SESSION TRACKER
Tap In / Maybe / Out as people reply. Invite the ins or everyone with one tap. Track who said yes then dropped.
SESSION HISTORY
Every invite is saved with the actual game date inferred from your "When" entry. Tap a card to see each player's RSVP inline.
GROUPS (Pro)
Create separate rosters for volleyball, pickleball, and poker. Copy players between groups.
CLOUD BACKUP (Pro)
Sign in with Google to back up your roster and sessions across devices.
PRIVATE BY DEFAULT
No account required. All data stays on your device unless you opt into cloud backup.
Free: one group, 20-player roster, 3 sessions of history.
Pro: unlimited (one-time purchase, $6.99).
Ratings & Reviews
New app icon. The Sessions tab now shows when you're eligible to unlock Activity Insights (fill rate, MVP, and more). Pro's full feature list — including analytics and cloud backup — is easier to see before you buy.
