Customizable - great task integration

If you use tasks (or apple reminders) like a list of items to-do on a given date (but without a time) then this is the app for you! It allows you to view them on your calendar and manage them easily - for example, uncompleted tasks carry over to the next day, can be quickly assigned to a different due date, and incorporated into projects.
App is also highly customizable - if you wish you can view weather, all day events, estimated time of arrival etc - so that you can make the app suit your workflow, rather than your having to change what you do to match the app.
I have been using this product for 10 years now - first on WinDoze mobile, then Crackberry, and now on my iPhone/iPad - and it is my most used, most important app.
But sadly the today widget is much less useful than previous versions, which showed start and end times aligned on the left so you could quickly scan your upcoming appointments (now that they are right justified you have to take an extra second or two to find the info).
