WhenWeGo: Group Trip Planner

Planning a trip with other people is a coordination problem: different free dates, different budgets, different departure cities. WhenWeGo makes that problem the centre of the app.

DATES THAT WORK FOR EVERYONE
Each person adds the days they're free (or the days they can't), how long they'd like to go and how flexible they are. WhenWeGo ranks the windows that work — and when none works for everyone, it says exactly who a window doesn't work for and by how many days, instead of hiding it.

COMPARE DESTINATIONS HONESTLY
Add the places you're considering. Each one is compared against everyone's travel time from their own city, their interests, their budget level and the month's typical weather. Travel times are labelled as estimates; weather is a recent historical average, never presented as a forecast.

ONE PLAN, MANY STARTING POINTS
Everyone travels from their own city. Two people can take different hotels in the first city and everyone can share an apartment in the second. Every stay, flight and activity has a status — proposed, selected, booked — and a cost that is labelled as a price someone saw, an estimate, or not known yet.

DECIDE TOGETHER
Dates, destinations and day plans become proposals the group votes on. The organizer accepts or drops them; accepting can be undone. Nothing changes under anyone's feet.

BUDGETS WITHOUT AWKWARDNESS
Your exact budget stays in your own iCloud. The group sees a budget level from 1 to 5 unless you choose to share the figure. Costs are split equally or by custom shares, per person and for the group, with currency conversion at European Central Bank reference rates.

AN ASSISTANT THAT ONLY SUGGESTS
On devices with Apple Intelligence, an on-device assistant can suggest a date window, a destination or a day plan from the group's actual constraints, and answer questions about the saved trip. It can only create proposals — people decide. Assistant inference runs on your device. Proposals you choose to create are part of the shared trip. Without Apple Intelligence, every other feature works.

BOOK WHERE YOU ALREADY BOOK
WhenWeGo does not sell flights or rooms and never shows invented prices. It opens Google Flights, Skyscanner, Booking.com or Airbnb with your dates and cities filled in; you enter what you found.

PRIVATE BY DESIGN
No account. Trips live in your iCloud and are shared only with the people you invite. No ads, no tracking, no analytics.
