Been here and there, everywhere a little bit Nozbe, Nirvana, Todoist, mindmapping software, Evernote, plain txt files, lists with tags, MyLifeOrganized, etc.
Since a while I’m on Omnifocus, running on an ipad next to my laptop during crunch time, and available on the laptop in a virtual machine (I run Windows natively) at the touch of a key.
For most things, OF has the best thought out solutions. Project settings (sequential, parallel, single actions), start and defer dates, repeat options on tasks and projects (due again, defer again), and the review feature are what keeps bringing me back to it.
Came across Evero through a mention by someone and love the look and feel of it and where it is going. Hoping for (repeating) defer dates.
Why switch? Once Everdo has an Android app I can just run natively on the desktop and check my focus items during the day on my phone. Feels like a bit cleaner setup than having to run a virtual machine in order to run a GTD app
