Here’s a little chart to compare Koalendar and Google Calendar appointment slots features for yourself:
Google Calendar Appointment Slots is a function in Google Calendar that lets you open parts of your calendar for meetings and appointments. When you convert a calendar event as an appointment slot, it creates a view of your calendar that only displays the available appointment slot and a shareable link to send to your invitees. The platform also allows you to treat an event as one single appointment slot or as a time frame for multiple appointments. Google Calendar Appointment Slots is free to use, but it can be difficult to set up. It also doesn’t allow you to customize its look according to your brand.
Koalendar is a great Google Calendar appointment slots alternative because it offers a clean, modern, and intuitive interface, for free.
Your invitees will get a delightful booking experience along with a customizable questionnaire to qualify them. You'll also enjoy a live and quick customer service, directly from the developer.
But don't take our word for it: feel free to try Koalendar free account.
