Very good, almost great...

9/2016 Update: I have had some sync issues with Office 365 which seem to have been fixed by deleting my account and going through the set up process again. Im not sure if this was caused by changes on our side or with the application.
I still think this is the best task app out there. Although now I would really like to see support for split screen (on iPad) and rich text in the notes. I frequently input links and other text in notes and I order to edit them from this app I have to convert to plain text- removing links and formatting.

Original review:
Ive found very few task apps have the features Im looking for. Categories that sync with an MSExchange server, for example.
TaskTask has the features but also a very simple to-the-point task list with custom filters and arrangements - that doesnt alter the format of my content created in Outlook. (I had an app that didnt show capitalization as it was entered.)
If it werent for a few bugs, like adding attachments to newly created tasks or not maintaining category changes, it would great.
