Coordinating a group calendar over chat is misery. Propose a handful of times, let everyone mark their availability in one tap each, and siono surfaces the slot that works for the most people — no accounts, no spreadsheet.
Free · no accounts · everyone marks their availability, best time wins
On the next step you’ll propose your own candidate dates & times — everyone marks yes/maybe/no and siono surfaces the slot with the best turnout.
Propose several options, share one link, and have everyone mark yes/maybe/no per time. siono scores each slot by attendance and shows the best one live — the fair, fast alternative to a long email thread.
Yes — propose times, collect availability, and see the winning slot, with no signup and no per-account setup. Times display in each person’s local timezone.
Every proposed time is stored in UTC and shown to each respondent in their own local timezone, so nobody has to do the math.
Propose your times, share the link, and let everyone’s availability pick the winner.
