I have said what Mickey is looking for. This is a good app. Visually appealing with a good feature set. Right now I'm on my BlackBerry z30. However, I'm Mac and all the other stuff all the way. I want a desktop version of the product with the for measures that could support and definitely do not like using the product in my browser. I feel so strongly about this that as much as I think this is a good GTD program likely what I'm going to choose is Swipes. Having come from Omnifocus I would have likely chosen Get it Done. But I so cant stand using it in a browser I've got three choices other than this that would work for me:

1. Swipes
2. Todo Cloud
3. Todoist

They're all good but I like Swipes ability to get things out the visual field temporarily. Get it Done with a Mac desktop app would have likely been my choice.

I just downloaded Opera Web Browser and set the app as my home page. I changed the settings to open the app on startup. I use Chrome or Explorer for web browsing and just use Opera for getitdone. Works for me just like a desktop application.

I would immediately use a Mac desktop version. Is there one available or on the way?

I completely agree, a Mac app that I could have loaded on my machine that then synced to the web version would be fantastic. If it could then also be visible without being disruptive to keep us on track of our tasks that would be great - DateLine is an example of how they have done this for iCal.
Very user friendly!

Need a Windows 7 app, as business users are not to Windoze 8 so quickly.

We have a Windows 8 app out now which can be found here:
