Sorry, yes, Drafts app is ideally a one stop shop for all data entry. Think of something you need to write down, open drafts, write it, then think where you are going to send it to - a specific note in Evernote, the clipboard etc.
Workflowy doesn't have any Drafts app function, although they DO have Memoflowy, which works a bit like Drafts and will add text, with various additions and processing specified by you, to a specific bullet in workflowy.
So for example I have a note in Evernote where I track my weight. I write the weight it in drafts, press the appropriate button in drafts and it gets appended in the Evernote weight note, with the date prepended etc. I'd just started using Memoflowy in the same way in Workflowy when I found dynalist.
