It offers great functionalities and it is free. It integrates with my calendar very well and it streamline booking meetings with external collaborators. I used it everytime I want to book an event with people outside my organisation. Connecting zcal to Outlook is super simple and it is very easy to create my custom meetings.

Even with its free tier, i can add multiple calendar accounts for checking my availability. Granted, the resulting calendar appointment must be written into the default calendar account.

I really love how zcal makes it extremely easy to share a meeting link with others - the link format is simple and memorable, which is incredibly convenient for quick access and sharing. I also find it highly impressive that when I share the link, my picture appears as a thumbnail in communications apps like WhatsApp and Telegram. This feature not only adds a personal touch but also makes it distinctly clear who the meeting links are associated with, enhancing the user experience. Setting up zcal was a breeze; the process was notably straightforward and didn't present any difficulty, allowing me to get started quickly. The ability to include different time zones within different links is particularly beneficial for coordinating with collaborators in various regions, and the option to pose custom questions during the booking process ensures I get the information I need efficiently. Overall, zcal's functionality and ease of use truly stand out.
