I have been a strict GTD believer and follower for the past 7 years. Back when I had a blackberry, I had To-Do-Matrix (produced by RexWireless) and it was still to this day the best GTD app I have ever used. Unfortunately they do not have an android app and they seem to have by and large stopped supporting the app. I have been using DoIt.Im for the last few years but am still in search for a better app and was wondering if anyone has any thoughts. The main capabilities and features (above and beyond basic and standard GTD functionality and organization) which I am looking for and unable to find in one single app are the following: - Ability to move projects from "Projects" to "Waiting for" overarching folders (or ability to do this by setting status of projects) - Ability to make Projects with subfolders with tasks within each subfolder - Easy and fast way to add items to inbox from mobile device - Usable and user-friendly desktop UI Any help or thoughts would be beyond appreciated.
