I keep flipping between Todoist & Evernote as the home for my GTD, particularly projects and tasks. I was also looking for a better way to time block. I came across Tweek, and as a partial minimalist who feels guilty for not using enough pen and paper but wanting to do something for the environment, this got me hooked.
I have given up Todoist and Moleskin for this app. I hope it becomes what it has the potential to be.
