Trying out a new calendar app called "Upto". So far it seems to have a simple UI and it is handy if you want to follow the schedule of favorite sports teams, TV shows, Movie Premiers or FB contact events, etc.
I have been using Business Calendar for quite some time and this app so far seems to be an improvement (primarily because of the UI). Wish it had a few more customizations for changing the appearance of the widget, however.
