Looking for a calendar/todo manager

[Aldarion]

Hi All,

I'm looking for a calendar + task managing app, specifically one that has the following features:

1. Creating multiple to-do checklists, which can then be displayed on the home screen as simple 1x1 widgets.
2. Creating repeatable events, including biweekly repetition.
3. Integration with Google Calendar, displaying different views (weekly/daily agenda, whole month, upcoming events etc.)

I've tried several apps, but none of them has all of the features I need:

• ColorNote is what I'm currently using for to-do lists, and it really is brilliant in that aspect; the 1x1 widgets for each list are just what I need. However, it has only a rudimentary calendar display.
• S Planner, on the other hand, is a magnificent calendar app, but the task lists are a bit wonky, and there are no widgets at all (I'm using Nova, so even the big widget is unavailable).
• Jorte was very interesting (and frighteningly customizable), but it permits only three (!!) different categories for tasks and has no biweekly events.

Of course, I could compromise and use S Planner in conjunction with ColorNote, but... surely there is something that would fit?
