Constraints layer up
School terms, partners' work travel, your mother-in-law's birthday — each person carries five or six soft constraints. Polls reduce them all to yes/no.
Use the dog to herd the cats.
WhenWorks.dog
WhenWorks helps friend-groups land on a date — from an evening out to a multi-week holiday across borders. Honest about preferences. Kind to fence-sitters. Ruthless about privacy.
No credit card. No calendar sync. No ads.
The pack.
Eight friends. Three countries. One window.
Eight friends. Three countries. One window.
The dog. Already on it.
WhatsApp polls weren't built for this.
Three friends, an evening dinner, two weeks away: a poll is fine. Ten friends across three countries, partners, school-age kids, a 10-day holiday nine months out: a poll is a small disaster in progress.
Fence-sitters are penalised
Most people are 80% sure, waiting on someone else. Existing tools force a premature yes or no — then count "maybe" as worse than "no".
Privacy is binary
You either share your whole calendar or none of it. There's no clean way to say "I can't, but I'd rather not say why".
Three steps. Six honest answers.
No app to download. No calendar to sync. Just an honest conversation about when works.
Create a group
1Name it, invite friends with one shareable link. Groups persist between plans — your friends stay your friends.
Mark your weeks
2For each week in the candidate window, answer one question: can you do this date range? Six options, not three.
Lock the strongest window
3The heat-map shows where everyone's green lines up. The Convenor locks the range; fence-sitters firm up. Export to ICS when confirmed.
Six answers to one question.
Every option answers “can you do this date range?” The scoring is weighted — the strongest dates rise to the top. The “don't know” option is neutral, not punitive.
Yes definitely
Locked in. Booking the flights. Counting the sleeps.
Most likely Yes
Eighty percent. Waiting on one small thing to firm up.
Prefer Not, but if I had to
It's awkward. You'd make it work if everyone else is there.
Don't know and I'm not willing to commit
Honest. Counted as neutral, not punished as a no.
Most likely No
Probably not. Don't plan around you, but check back.
Hard No
Take it off the table. No room. No further questions.

What's in. What's out.
A focused tool earns its place by what it refuses. Here's the line we drew, and where to go for the rest.
What it does
- Group availability across long candidate windows
- Heat-map view of where everyone aligns
- Plan lifecycle: Discovery → Locked → Confirmed
- Honest, nuanced responses — not yes/no/maybe
- Privacy controls. Decline without disclosing why
- ICS export. WhatsApp share. No lock-in
What it doesn't do
- Calendar syncStay in Google or Outlook. We don't need access.
- Travel bookingUse Wanderlog once the dates are locked.
- Expense splittingSplitwise is already good at this.
From spark to schedule.
Ideas don't wait for a convenient moment. The ⚡ button captures anything — a link, a note, a photo — in seconds. Your WishList turns captures into structured ideas. When the time is right, propose one to a group and let WhenWorks take it from there.
Capture in seconds
Tap ⚡ on any page to open the capture sheet. Paste a link and WhenWorks fetches the title and preview image. Drop a photo. Or install WhenWorks to your home screen and share directly from any app's share sheet — two taps, zero copy-pasting.
Build your WishList
Promote a capture into a structured idea with a category, duration, and a target date range. Browse your WishList as a Kanban board, a Gantt timeline, or a year-view calendar. Spot clashing aspirations before they become arguments.
Propose when ready
When the moment feels right, propose a WishList item to a group. The plan form pre-fills from your idea — title, duration, candidate window. The group submits availability; the heat-map finds the window.
