Reviewers mostly praise Vimcal for speed, keyboard shortcuts, and a polished interface that becomes intuitive after a short learning curve. They repeatedly highlight strong handling of multi-account calendars, duplicate meetings, time zones, and easy sharing of availability, with several saying it replaces separate scheduling tools well. Support and onboarding also stand out as responsive and helpful. The main caveats are narrower: some worry the product feels a bit dated and lacks roadmap visibility, one wants better task time-blocking, and another left because support did not extend beyond Google.
