This has always been my favorite calendar (since the days of my Centro). It does have a "learning curve", but once you get used to it, it works great. In fact I love it now, but don't even use its full capabilities yet. It continues to get better.
I've been using Pimlical since my Palm days. Nothing compares to its versatility and ease of use (once you get past the learning curve). And the technical support, direct from CESD himself, is prompt and always helpful. Every update is just icing on the cake! October 7, 2017: just keeps getting better!
The best complete personal organizer out there. It is sophisticated with a high learning curve, but it will do things you will need to have and cannot get anywhere else.
The best calendar app by far! Keeps me on Android. Wish Apple would accept Pimlical as well.
The program is very good. A few more settings would be good, like those with colors and features for faster user experience (copy paste drag...) . But... Android is informing me under permissions, that program is created for older Android. It is not compatible with any other widget or anything else. Bravo! Two little stars!
