什麼是 Whennn？

Because "when is everyone free?" shouldn't turn into a 47-message group chat. Whennn is a quick and easy scheduling tool — share a link and friends tap what works for them on a visual month calendar, morning, afternoon, or evening. No sign-ups, no downloads, no group chat chaos. Guests respond with just their name. No personal information collected. The host sees availability at a glance and locks in a date.
