Whenna

Pick a fundraiser date that draws the crowd

Turnout starts with the right date. Share one link with organizers and key guests, see which day wins, and lock it so the room is full.

Start a plan — it's free
No signup. No app. One link.

How it works

  1. Make a plan in one tap and share the link anywhere — group chat, email, anything.
  2. Everyone taps the times they're free. No accounts, works on any phone or computer.
  3. The best time lights up live. Lock it in and everyone adds it to their calendar in one tap.

Common questions

Does everyone need an account?
No. Nobody needs an account or an app — people just tap the link and mark the times they're free. It works in any browser on any phone or computer.
Can it handle a recurring fundraiser?
Yes. Plans can repeat daily, weekly, or monthly — including patterns like "the first Wednesday of each month" — and the locked time lands on everyone's calendar with the repeat built in.
What does it cost?
Nothing. Whenna is free, with no ads and no selling of data.
How do people remember to show up?
Anyone can turn on an email reminder before each occurrence with one tap, and everyone can add the locked time to Google, Apple, or Outlook calendars instantly.
