Plan events together. Find the best dates, build itineraries, split expenses, and keep your whole group on the same page.
Yes. Zwier is free on iOS and Android. There are no in-app purchases, no subscriptions, and no ads.
The organiser proposes a handful of candidate dates. Everyone invited marks which dates they can make, maybe, or can’t. Zwier then shows which date works for the most people so the organiser can confirm it and lock it in as the event’s date.
Invitees open a shareable link and can see the event immediately. Creating an account is only required to RSVP, vote on polls, or claim tasks. Sign-up is free and takes a few seconds with Google, Apple, or an email code.
Zwier is built for group events: bachelor parties, bachelorettes, baby showers, birthdays, weddings, trips, parties, dinners, and custom occasions. Multi-day events are supported with per-day itineraries.
Log who paid for what, and Zwier calculates a running balance for every group member. When the event wraps up, the Settle Up view shows the minimum set of payments needed to make everyone even.
Yes. Zwier is fully localised in English and Dutch (Nederlands), including the date finder (datumprikker), itinerary, expenses, polls, and tasks.
