Choice Limitby Tiny Add-ons

Office hours in Google Forms, one person per appointment

List your appointment times and let one person book each. A booked time closes on the form a few seconds later. If someone else picked it at the same moment, they go on the waiting list and are told by email.

Free for one form up to 25 responses. Then $12 once, with no subscription.

The options and their limits

Six appointments of 20 minutes, one person each. A booked time closes on the form straight away.

In this example 2:20 pm is full and two people are waiting for it.

6 places in total. That fits the free plan, which covers up to 25 responses after limits are turned on.

What people see

People fill in your ordinary Google Form. Under the question they see how many places are left for each option. A full option is hidden, or marked "full, join the waiting list".

  • Anyone who joins a waiting list gets an email with their number in line.
  • When a place opens up, the next person gets it and an email saying so.
  • Emails come from your own Google account, so replies come to you.

Good to know

What Choice Limit does and does not do for this kind of form. Read the help page for more.

  • Someone cancels

    Press Free this place in Your list and the time opens again on the form.

  • Calendar invites

    Choice Limit does not add bookings to a calendar. If you want calendar invites, Google Calendar's appointment schedules may suit you better.

  • Two people at the same moment

    If two people book the same time within a few seconds, the second goes on the waiting list and gets an email.

  • Every week

    Over a term, your responses can pass 25, the free plan limit. Unlocking costs $12, paid once.
