We've all been there

Stop texting "does Thursday work?" to 12 people.

WhenWorks reads your calendar locally, shares only free/busy windows, and finds the time that works for everyone. No polls. No back-and-forth. Just done.

How it works

Three taps. Everyone's in.

01
Create an event
Name it, set a date range, invite your people. Takes 10 seconds.
02
Calendars sync locally
Everyone's calendar is read on-device. Only free/busy windows are shared — never event details.
03
Vote and lock in
The group sees overlapping free times, votes, and the best time wins. Done.

Your calendar data never leaves your phone.
Not to our servers. Not to anyone. Ever.

Coming to iOS soon.

A new way to plan with friends and family — built quietly, in Sydney. Have a question? .
