The clean layout and constantly evolving features make it really easy to navigate and great value. It has good integrations with other websites and really quick to load as well. It's made my ROI really high and works great. Review collected by and hosted on G2.com.

There's nothing I dislike, it would be cool to have some AI integrations with things but it not at all necessary Review collected by and hosted on G2.com.

I love that it provides a single calendar view and that it has the option to only share free/busy info across calendars. Review collected by and hosted on G2.com.

nothing, really! The price seems a little high, but yet it's still well-worth the investment. Review collected by and hosted on G2.com.

It’s easy to set up synchronization, it works well across multiple platforms, and the UX design is great. Review collected by and hosted on G2.com.

Calendars don’t always sync in real time between them, so I have to trigger the sync manually. Also, we can’t add a buffer to the sync, which is a must-have and something the team really needs to work on. Review collected by and hosted on G2.com.

I use OneCal for calendar sync as a freelancer with multiple calendars, and I love that it's quick, efficient, and keeps my calendars all in one place. It's very easy to set up and use, which makes it a great tool for managing my schedule. One of the big benefits is that it allows all my teams to see up-to-date calendar times, keeping everyone aligned. Review collected by and hosted on G2.com.

When looking at all my calendars at once, I see 4 events each. On mobile, especially if I have an all-day event, I see 4 events for 'busy', then I have to click and see the actual event. Review collected by and hosted on G2.com.

Onecal is simple to set up accross your accounts. It immediately starts sharing your calendars across all your chosen calendar apps. Prior to this, I had constant problems trying to overlap my work and personal timetables. Our family just couldn't find one source of the truth for all the activities we were doing. Onecal solved this for us, and we have never looked back. Review collected by and hosted on G2.com.

I don't, once it is set up, it stays in the background doing exactly what I need it to do. It just works. Review collected by and hosted on G2.com.

I really like how OneCal is completely effortless, and it has stopped double and triple booking between my calendars. Setting it up was very easy, and most of the time, it just works effortlessly. Review collected by and hosted on G2.com.

Every once in a while, and I mean like every few months, I have to go in and manually rerun the sync between the calendars. But it's almost unnoticeable. Most of the time, it just works effortlessly. Review collected by and hosted on G2.com.

OneCal makes it easy to manage multiple calendars across different accounts while preventing me from overbooking. OneCal's focus on calendar synchronization makes it extremely easy to use, and the service is reliable beyond belief at a reasonable price. Review collected by and hosted on G2.com.

I have used many competing products and have not found anything to dislike about OneCal. Review collected by and hosted on G2.com.

I really like OneCal for its seamless experience and the fact it just works. I appreciate how it allows multi-to-multi calendar synchronization, making it possible to synchronize my work, private, and business calendars effectively. I also find the initial setup to be quick and easy, which is a huge plus. After trying multiple calendar tools, OneCal is the first one that actually works for me. Seeing events from my unshareable work O365 calendar, in my private Google Calendar, also makes a big difference. Review collected by and hosted on G2.com.

synchronization of updated events is sometimes bumpy. Review collected by and hosted on G2.com.

The application functions as a Proxy between the connected accounts, allowing me to "play" with synchronizations without having to worry about creating duplicates or leaving traces between old and new settings. Priceless in my opinion. Review collected by and hosted on G2.com.

Currently, it does not integrate the management of Outlook categories (microsoft365), so it is not possible to choose the colors of events copied to Outlook. On the Windows app/OWA side, the default is gray, and on the Android app side, it is the same as the calendar... not always easy to recognize "on the fly" compared to work appointments.

I love being able to sync multiple calendars into one and the ability to color code appointments based on which calendar they’re associated with. Review collected by and hosted on G2.com.
