Whensday

See when everyone's free.

Whensday is an iPhone app for making plans with friends. It puts your calendar and your friends' calendars side by side, so you can see when everyone's actually free before you suggest a time.

You create an event, invite people, and they RSVP. Friends see the hours you're busy, never what you're doing, and anyone you invite can answer from a link without installing the app or creating an account.

What Whensday does

See who's free

Your friends' calendars next to yours. You see when they're busy, never what they're doing.

Plan around real schedules

Pick a time that actually works, create the event, and it lands on everyone's calendar.

RSVPs without accounts

Share a link. People reply straight from the browser, with nothing to download and nothing to sign up for.

Works with Google Calendar

Connecting Google Calendar is optional. Turn it on and Whensday syncs both ways, so your friends see an up-to-date picture of when you're free even while the app is closed.

We read only the calendars you tick, and we write only to a calendar called Whensday that we create in your account. Your existing calendars are never written to. Events we import reach your friends as a block of busy time, with no title, no notes, and no location.
