Inadequate but useful


BusyCal on the Mac is great. I use it nearly every day. However, BusyCal for iOS is woefully underpowered. While it's a useful way to see all of my to-dos at once, or to get an overview of my calendar, the lack of secondary sorting for to-dos (by priority, then creation date, for instance), and the inexcusable lack of BusyCal for Mac's premier feature, filters—where you can show any combination of categories you like instantly—drastically reduce its usefulness.

The filters don't have to sync with the Mac; I may want different ones on the road anyway. But this is a crucial feature that has been bafflingly absent from this app for years. If this comes as a paid upgrade or an IAP, fine. But without it, this app is not really more useful than the stock Calendar app, and only somewhat more useful than Reminders.

Very disappointed

the toxmeister

I have been using BusyCal for Mac for years and I am a satisfied customer. I recently purchased BusyCal for iOS to see if it could replace Fantastical. So far it works well on my iPad but it is a bust on my iPhone running the latest iOS 11. On the iPhone it cannot add events. Half the time when I press + to add an event, nothing happens. When the new event screen does open, I enter the event info and when I press Done, nothing happens. The app just stalls. Also, you can't open an event to look at. You can select an existing event (obviously creatd in another calendar app) until the cows come home and the app just sits there and does nothing. I have restarted the phone to no avail. Something is seriously wrong here and needs to be fixed.

Apologies, can you try v3.3 and let us know if it hasn't worked for you? Contacting us via our support webpage would allow us to get back to you quicker. We'd appreciate an updated review.

Best Calendar App


This is simply, the best Calendar App, available for iOS. It’s clean and nice to look at, syncs flawlessly, with other Calendar’s and is very easy to use. It also offers sync capabilities with iOS Reminders, which is a must for a Calendar App, in my book.

You can quickly add an event or to-do with all the information you need and clearly see the month you’re in, from any screen.

If you are looking for a replacement Calendar for your iOS device, look no further, because BusyCal is a winner.
