As we continue to work hard on the GTD Reviews redesign, we feel it’s important to keep our information current and relevant. Today we’d like to review the apps listed in our Mac App Comparisons page, explain the changes we have indexed, and review what’s new in the world of Mac for GTDers.

Today I opened up the App Store on my iPhone 3GS, and was pleased to find a major update for OmniFocus! The popular GTD app for iPhone and Mac has updated for the new iPhone 4 that is released tomorrow, and for the multitasking abilities of the new iOS 4 from Apple.

What I am curious about is what you’re looking for in a GTD app. No really. What makes a productivity app great to you? Have you thought about it at all? I have. For me there is one thing that matters most…

In our recent review of the GTD Implementation Guide, I made mention of a category of GTDer that is “on their way to black belt,” and I’ve been asked to elaborate on what that means. My goal in this update is to shed some light on black belt from my perspective, but more importantly share with you some resources that have helped paint the picture of what a GTD black belt looks like.

Here on GTDReviews we are in the process of indexing and reviewing all the various applications made for GTDers. A lot of that is in the works, but in the meantime I’ve been reflecting a lot on capturing non-digitally. As I said in my last post, I’m in between phones and just moved to a new computer, so capturing thoughts has been somewhat haphazard lately.

What happens when you’re in a place where a little notebook and pen won’t do you any good? Or you don’t have any digital device capable of recording, sending or saving any thoughts? That place is the shower of course.

Since the $20 GTD Implementation Guide was released a week ago, we’ve been wondering what role it serves for new and veteran GTDers alike. Fortunately, I have recently been feeling quite a bit out of control after getting married, moving, and I had yet to fully re-implement GTD. So I started from scratch using the guide to walk me through the process. In this review, I’ll share what it will do for you – and what it won’t do.

We’ve downloaded the full GTD Implementation Guide and we’re excitedly pouring through this new resource. The goal? Determine its place and relevance in the implementation of GTD for newbies, as well as assisting current GTDers stay on top of their game.
