Used to be great! Transient error again

Not sure what happened but this used to be my favorite app. I run my life by my task list and when this app works, it's GREAT! Unfortunately it works less and less and crashes more and more. Transient error occurred during syncing error is back. I'd much rather the developers fix this than me having to find a new one because it was once AWESOME! I'll hold out for a little while. I’d even pay more for this working app

Do not buy. (I’m a productivity coach.)

I’m speaking as the creator of the TRO productivity system. We review apps and provide specific instructions for managing task lists and projects for GTD and TRO. Not only does TaskTask provide no means of sorting the task list except by due date or drag and drop, it permanently mixes all flagged emails in with your tasks with no way to separate them if you purchase additional task attributes ($0.99). The Folders screen now shows that I have 10 tasks and 1200 flagged items, but when I tap the Tasks folder it shows me everything, all 1210, not just the 10 it said I have. What a mess. And there is no way that we can see to undo the purchase or turn that feature off.

I had high hopes for this app, because Exchange access for Tasks is very needed. Sadly, we are unable to recommend it for any of our clients. Avoid.

With even Microsoft providing poor support for Tasks on the iPhone, Outlook tasks are quickly becoming an obsolete way for task management. We recommend Toodledo instead if you can possibly use it.

Works flawlessly

I use this daily to sync my Outlook / Exchange tasks to my iPhone X and it works flawlessly. Lots of options on how to sort and it captures many of the outlook fields. The syncing is fast and reliable. It’s straightforward and fast to add tasks.

TaskTask works great for Michael Linenberger’s MYN task tracking system. I suppose it would work well for other GTD-like systems too.

There aren’t too many options on the iPhone in 2018 for Exchange task system. This app is a lifesaver and is far better than Microsoft’s anemic ToDo app.
