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 good start

[review updated for 3.33] After using BusyCal on the Mac for many years, I'm glad to see them come to iOS. This is my favorite calendar app, and they've been busy improving it.

Good: nice layout, with easy access to each view. List & Month views (the ones I use the most) are well thought out. Better todo-calendar integration than competitors. Week view scrolls by day (not full weeks) & Month view scrolls by week (not full months) - very helpful near end of the week/month.

Needs improvement: While viewing an event, must click Edit before editing some fields, rather than just clicking on the field. Day/Week views should allow creating events by touching & holding at a specific time. Can't drag events to new days in Month view (only in Week view). ToDo view should allow on-screen selection of which calendar(s) to view, not just how to sort todos on the screen.

Fixed: font size setting for Week view (3.04). Replaced date slider with calendar picker (3.1). Create events with touch & hold in month view (3.33).

Very disappointed

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.
