No More Scheduling Woes

I’ve been using OneCal for a couple of years now and love it. I first started with the desktop and now that the app has come out, life is even easier. I love that it lets me see all my calendars at once without going through the hassle of syncing them (though you can do that if you want). I checked out A LOT of calendar syncing options and OneCal is by far the one that works best for me. I use it for booking links, too. The company continues to add valuable features without making the product so complex that it breaks/ glitches. The only slight drawback is that it does take a beat to load each time you access it. It’s a small price to pay for finally feeling organized and on top of my calendars!

Response from developer

We're happy you're enjoying OneCal, appreciate your feedback. Regarding the first load time, it depends heavily on how many calendars you've connected to OneCal. Even though you should be able to see your old events as soon as you open the app, we show a loading indicator to let you know we're fetching the newer events across all your calendars. That said, I've forwarded your feedback to the team, and they'll do their best to improve the functionality. Cheers, The OneCal Team

Finally

App works really well. Has helped me manage different calendars in one place, and keep everything synchronized.
I can have a link sent to clients where they go through my availability, schedule meetings, while keeping my calendar private–no one sees actual event descriptions but me. Removed the wasted time in back and forth communication trying to find a date that works.
Great!
