Have used this calendar app for years and it's just what I need. I recently switched phones and had trouble linking my license for the purchased upgrade. I emailed the support team and over a couple of days they walked me through fixing the issue. Thanks for the great support, and now I'm back to using my favorite calendar app!

Best if purchased because it has all the features I was looking for and missing from Google calendar. I like making recurring weekly appointments that exclude some days. Couldn't do it with Google calendar which notifies me. Had trouble at first after making the purchase on my phone because it did not transfer to my computer. But with the great assistance from support everything is working. The platforms do not cross and you have to do a little tweaking to make it work Thank you support.

Very useful, no nonsense. That says it all. Very useful to aggregate multiple calendars from multiple accounts, and also from other sources (ical feeds published by college clubs, for example). Suggestions for future improvement: - Ability to sync more frequently than every hour - Filter on/off calendars individually, rather than grouped by color
