What is so special about this app? – Fantastical Calendar Review

I paid for this thinking it would make my life easier and more organized. So far I cannot see how it’s any different than the calendar I previously had on my phone except that I paid $ for this one. I like the visuals better but don’t like that it dumps all my tasks from the iPhone app I haven’t used in 2 years... and I can’t figure out how to add tasks to this calendar it seems to just carry over from the old one? Why? What’s the point? I’m willing to change my review if I discover how to actually use this app and actually find it useful
