whenyoufree? is a scheduling tool that helps groups find a date that works for everyone — no app download or account required for participants. Organisers create a free event, share a single link, and their friends tap the days they're free; the organiser instantly sees when everyone can make it. Pro users pay a one-time lifetime fee or £1/month for features like locking a confirmed date, nudging non-responders, and running unlimited events.
