We struggled getting tasks entered Evernote into our task app (e.g. Omnifocus). Didn't too much like the idea of cutting and pasting from our meeting notes - we like automatic better.
We built TaskClone to solve that problem. TaskClone copies or "clones" the tasks from Evernote (associated with an EN checkbox) and sends them to Omnifocus as a task and the note link is added as a note to the task in OF so you can get back to the notes that contaned the task for reference.
Several OF users are already finding this useful and we hope it helps others. You can see a quick 2min video of the process or checkout the homepage below.
