Reviewers mostly like zcal for its clean, attractive interface, simple setup, and smooth 1:1 scheduling, with several saying it is easy for both clients and teams and useful for personalized booking links and calendar syncing. But the praise is tempered by repeated gaps in deeper functionality: users ask for stronger team booking tools, multilingual support, bulk editing, cancellation controls, add-ons, and better Apple/iCloud calendar support. One sharply negative review also says support is poor and some polished-looking details break under real use.
