Overview
Free appointment booking and scheduling for Google Calendar™.

Share one booking link. Clients choose a service, pick from the times you are available, and the appointment appears in your calendar as a normal event.

FREE TO INSTALL AND USE
The booking page, your appointment types and your availability settings are all free. There is no trial period to run out.

BUILT FOR BUSINESSES WITH MORE THAN ONE SERVICE
Most free booking tools give you one appointment type. This one does not.
- Multiple appointment types — different services and durations, all from one link
- Buffers before and after appointments, so back-to-back bookings do not run into each other
- Minimum notice periods, so nobody books you ten minutes from now
- Availability set day by day, with closed days and holidays excluded
- Automatic time zone detection, so clients always see times in their own zone
- Booked time never shows as available, so the same slot cannot be taken twice

HOW IT WORKS
1. Connect your Google Calendar™
2. Click the "Appointment Booking" blue grid icon in your Google Calendar™ sidebar to open the app
3. Set your availability and create your appointment types
4. Share your booking link — every booking lands straight in your calendar

WHAT YOUR CLIENTS SEE
A clean two-step booking page. They pick a date and time, then enter their details. No account to create and nothing to install.

I just want my form to give the options A, B, and Other___ without any changes. With this add-on, anytime someone submits a response under Other, it automatically gets added to the form as a new option in the list. Please give us a way to turn this feature off.

A bit confusing, because how do I change from collecting users phone numbers to collect an email address instead? Support email does not work either

Great addon....But please! please!! please!!! Can you provide a way to "TURN OFF" the feature that updates the options list with whatever a user writes. Because a rogue user can write anything crazy... and that 'thing' automatically reflects in the survey that other participants will now see. Thanks.

crikey, that was easy! no code needed and works seamlessly into the native setup. Does everything you'd hope with no bugs: a time lag of less than 2 seconds to feed it into the form, 'submit another response' includes the new option - and - even the user using the browser backpage shows updated form! Thanks devs!

DO NOT USE unless you are OK with what someone types under "other" being added to your form. It retains what is typed, adds it to the form, and it appears to the next person completing the form as an answer to choose.

I cannot use this add on for checkboxes because the checkbox does not offer the "other" option. It only allows me to "add column". It worked great for multiple choice but not what I needed it for.

It's very good tool to use if you trust the people that are answering your form, I just wish we had a add-on to change the text "other" to something else, like "self describe" or "if yes, which one".

I wish I had a add-on to change the text "other" to 'Comments", and to be added to the end of each item inside a question.

Excellent add-on. But I would like the option to NOT include one person's "Other" to the official list for other people.
