Fantastic cross-calendar/device/OS app - THANK YOU!!!!

I rarely write reviews, but feel obliged to write one for this wonderful app that finally solved my calendaring problems that were costing me no end of time and missed appointments. I work mainly on Windows with personal email on Microsoft Exchange accounts and organizational email in Google, and also use two iOS devices. I tried pulling all calendars into my Microsoft account, but synchronization was undependable. I tried an on-line calendar sync service and that immediately altered many appointments in a group calendar — really bad. I spend a lot of time checking one calendar against the other. Finally, this One Calendar app has solved my problems. I consider the price I paid for the Premium version on iOS and another modest fee for the Windows app a small price to pay for all the time it has saved in the few weeks I’ve been using it. Not only that, but the user interface is extremely well thought out, very easy to figure out with good customization options. The month and week views are far better than Outlook or Google IMO. Thank you, thank you, thank you. Keep up the great work!

Finally - a calendar which provides applications for my Windows PC, my Mac, and my iOS devices!

I use a Win 11 laptop, an iPhone, an iPad, and a Mac Mini. I used to rely on iCloud for Windows to integrate my Apple calendars with my Microsoft Outlook calendars. Always quirky, it finally stopped working. Now I use this wonderful tool which rapidly presents my Apple, Google, and Outlook calendars and lets me update them from every platform. Love the fact that it doesn’t need a browser, but instead provides native apps for Win, iOS, and Mac OS. Thank you, thank you, thank you - well done!!
Update: I had one intermittent problem in Mac OS. After a couple of e-mail exchanges, the developer figured out the problem, told me what to do, and now it’s fixed. Couldn’t be happier!

Would recommend

Love this app. As a forgetful college student it does wonders. great for people who like organizing by color and seeing visual differences in your schedule. The notification feature is really simple, and it’s very easy to add/remove events. My one problem is that event colors are only in the premium deal, which means my whole schedule can be one blue blob. But, since you can synch this calander app with google calendar I’ve found a way to work around the premium deal and still get pretty colors via google calander on the computer. Would recommend if your forgetful and like pretty schedules like me :)
