Never say never I guess! So after working for quite a while on mobile and not having it go as fast as we would like, we've taken a few weeks here to release a version of GTDNext that is fully responsive and works very well on mobile and tablet browsers.
It's not the "simple" version that you requested, it's actually the full app. There are still a few more features coming and I'll save the blog post until those items are done, but starting with 184.108.40.206 that was released today you can now utilize GTDNext fairly well on mobile browsers.
So fire up those iPhones, iPads and Android devices and give it try. How does it work for you? What would you like to see added or changed?
