iPad Productivity Calendar/Task List app

[ShadowNinja]

Hi All,
I'm looking for a good calendar and Task List app so I can work more productively. Is Calendars by Readdle any good? I have trialed but the free version doesn't do tasks so don't won't to pay unless i now it will be good and do what i want.
I use google calendar on my phone but I'd like to use the iPad to have task lists of things I need to do. Ideally have basic like - today, this week, someday. and have different lists like work, personal and then have separate lists.
and then add things to calendar etc that can sync. Hopefully i have explained well what I'm after.
I'm happy to pay for an app. Basically after a good productivity app for iPad so I can have that on desk separate to laptop.

Best Calendar app?

What’s the best calendar app for iOS? I’ve tried the stock apple app and fantastical and like some features on each but was wondering which apps others use and if there’s any other recommendations. What calendar app do you use?
