I still use this over the other options I bought here, as well as versus software like calendly. It is simple, easy to use, always works, and looks professional.

The sms reminders are what keeps me from using my other options however, while there's nothing missing I feel other software is improving at a much faster rate in terms of customizability and features. I think if zcal is going to remain viable in the long term it needs to start adding features at a faster rate. The ones they are adding and improving however are the most important, and at this current moment they have the best ltd calendar out there. Please continue to add to this amazing software, particularly around branding/cname as it's becoming a necessity to be able to white label client facing applications in my opinion.
