I've tried using Acreom for a couple of my projects. The app defo has potential. However, I could not wrap my head around their concept of "inbox". In Acreom, the "inbox" means all the unscheduled tasks. However, in my workflows, I often juggle multiple projects at once, and not all tasks have a set date yet, or I just want to do them "sometime in the future". The inbox is cluttered and useless as I see the same tasks repetedly until I schedule them.

In my head (and, I am sure, in the heads of other GTG users, too), inbox is just a parking lot for all the not yet organised tasks. Once a day, I go through my inbox, assign all the tasks to the coresponding projects and MAYBE schedule them. In this sense, Acreom does not support my workflow :(

However, as I see the upsides of having tasks intercalated with project notes, I'd consider giving Acreom one more go once a better task organising system is implemented.
