I recently switched over from the original business calendar app which I have been using for many years. This version has a fancier UI but functionally seems much the same as far as the calendar goes which is fine, if it ain't broke don't fix it! I think other features have been added but I don't really use them. Update: full screen ads suck. They appear and cannot be closed for a long time. Show me an ad if you must but let me close it, the free version is unusable this.
