"Having multiple calendars has always been a pain. Missed invitations and unclear availability made managing schedules a nightmare. Thanks to OneCal, my team and I are always on the same page, and scheduling meetings is a breeze. "

Managing multiple calendars is frustrating. I've tried other calendar syncing solutions and many of them cause massive duplicates, have a horrible UX, or are way too expensive.

OneCal is a perfect blend of everything making managing multiple calendars easy and cost-effective. I highly recommend it.

"By natively syncing bookings through the Google/Microsoft APIs, versus adding other calendars in 'view only' mode, OneCal effectively prevents conflicts within each calendar. Also, syncing all of these work calendars to a personal calendar (or their web UI) gives you a single pane of glass to work from (e.g., if you're manually scheduling an event over the phone or trying to find some free time in your day).It was easy to set up & has a good number of options to maintain privacy & security across calendars. I am not worried that Client X will see that I am meeting with Client Y - if they look at my calendar, they'll just see 'Busy.'"

"While OneCal isn't managing projects, it is keeping my workload manageable and the monotony of checking multiple calendars at bay. This means I can go to any calendar for an accurate display of what's happening in all of my calendars.Ultimately, it saves me a lot of time and rids me of calendar anxiety."
"You have such a beautiful and well-designed UI for an app I plan on setting and forgetting! lol"

"OneCal solved ALL calendar issues!
I have 5 different gmail calendars and OneCal is like, 'Not a problem!'

I need multiple booking links - OneCal - 'Not a problem.'

I had an issue (user issue for sure) and A REAL PERSON from OneCal is emailing me with a solution before the end of day.

"This has been a true life-saver to have updates syncing in real-time and eliminates the need for a third-party calendar sharing view for me. Was a breeze to set up as well. Thank you for inventing this!"

"During my search for a meeting scheduling solution, I discovered OneCal. I realized that it could effortlessly address all my calendar-related issues. The setup process was incredibly intuitive, and I can't think of a single drawback to this solution. I had it up and running in just three minutes. "

"It's a once-and-done setup, a few minutes to add and sync the calendars and then you never need to touch it again. And reasonable permissions manifest as well.OneCal has been head and shoulders above any other interaction I've seen, with responsive devs eager to explain their design and even implement new features."
"Far too often I've had to send the message: 'Sorry, I know my calendar looks open at that time but I actually have a conflict.'! This is going to take a lot of manual scheduling effort off my hands so I can stay focused on the real work!"
"I've just signed up and it's been what I've been looking for a while."

"OneCal is the best service I have found for calendar synchronization and management. I synchronize seven calendars using a combination of Google Workspace and Office 365 calendars, and OneCal keeps everything in sync. It offers me an easy way to manage my busy schedule across seven engagements. The game changer is OneCal's customized booking links, each customized with a unique logo.I have tried other services, and while they work well, none work as quickly and cleanly as OneCal."

"As a contracting firm, we need to maintain independent calendars for all our clients with a unified Master Calendar to book our consultant's schedule in real-time. Maintaining these manually was an impossible task. We tried several solutions from different sync products but no one got it right until we found OneCal. Great product, easy to set up but what really brought it home was the technical support. Support staff helped us understand the best way to set things up to get exactly the end result we needed."

"Your UI is just so much better than the other platforms I've tried!"
