It solves the problem of having multiple calendars and, even after several years, it continues to work smoothly. Review collected by and hosted on G2.com. What do you dislike about OneCal? The price seems a bit high to me, and the issue of being able to add it to my page to get appointments with potential clients also needs improvement.

General Practitioner 5/5/2026 "Instant Synchronization, Needs More Customization" 4.5/5 What do you like best about OneCal? The synchronization is instant, the setup was very easy to do, and it also allows me a calendar view that hides duplicates, making it much simpler to look at. Review collected by and hosted on G2.com. What do you dislike about OneCal? There could be more customization regarding the different types of calendars, such as which one you would like to use as the main one, or how to synchronize each one. To be able to do this, a large number of synchronization methods must be used, and that has a higher cost. Using all-to-all synchronization is a bit more unspecific. Review collected by and hosted on G2.com. What problems is OneCal solving and how is that benefiting you? Allows synchronizing all my calendars, avoiding overlapping appointments.

I also like that it automatically distinguishes between meetings that require Teams and those that require Zoom.

I found it very easy to set up and to add additional team members. Review collected by and hosted on G2.com. What do you dislike about OneCal?
