I bought this a week or so back and have thoroughly enjoyed it.

I have been using it for managing a project, and very much like the KanBan board. Specifically, I like that in task description you can make arbitrarily nested lists that each have their own checkmark. This is surprisingly lacking in many tools and often sends me back to a combination of OmniOutliner and Kanboard for a lot of planning. This app has been doing well at meeting my needs from both of those tools in one place.

I think the Docs tab is going to enable me to write the long-form project documents I usually do at the start of a project in this tool, instead of a google doc. If so, it'll replace three tools and keep everything in one place.
