Sweee is a free, no-sign-in scheduler for casual plans. Hosts paint up to seven candidate dates and choose a time range, then get a shareable invite link in about seven seconds. Friends open the link and paint the times they’re free—no app, account, or checkbox grid. Sweee turns everyone’s answers into a live heatmap, ranks the best overlaps, and lets the host finalize the plan and add it to any calendar.
