KITEREN
The ad-free RSVP app that gets your group together — fast.
Simpler communication for clubs, teams, and the small groups that matter.
Sound familiar?
Important messages get buried
Critical RSVP requests get lost in the chat noise and slip past everyone.
Tallying is tedious
Counting "yes" and "no" replies one by one and tracking them in a spreadsheet.
Chasing replies is awkward
Repeatedly asking quiet members "any update?" never feels comfortable.
Three steps with Kiteren
The organizer drafts a message
AI Assist turns your bullet-point notes into a polished, friendly invitation.
Members reply with one tap
Hit a button when the notification arrives. No second-guessing.
Auto-tally and remind
RSVPs update in real time. Anyone who hasn't replied gets a gentle automatic nudge.
Features
One-tap RSVP
Three buttons — Going, Maybe, Can't go — with satisfying haptic feedback.
Quick poll
Add one more question next to the RSVP — up to four choices. People without the app can answer from the web, too.
AI-assisted writing
Type a few bullet points and on-device AI polishes them into a clear invitation.
Supported devices only (iOS 26 or later with Apple Intelligence / Android with Gemini Nano). Processing stays on your device.
Join instantly via QR
Scan a QR code and you're in the group in three seconds.
Reliable push notifications
Only what matters reaches your phone. Auto-reminders catch anyone who forgot to reply.
Auto-reminders are a Personal plan feature (the free plan includes 5 manual reminders per month).
Ad-free, always
Zero ads, zero distractions. Nothing competes for your group's attention.
iOS & Android
Same experience on iPhone or Android — bring everyone along.
A great fit for groups like…
Sports teams
School clubs
Hobby & social circles
Meetups & dinners
