We know that using hubski on a small screen can be a pain and we've had a number of people ask for mobile apps or mobile versions of the site. I have personally spent a lot of time (mostly in class) fumbling around with hubski on my phone and before I joined hubski was working on an Android app. In order to give as many users as possible a pleasant mobile experience we have been working on a mobile version of the site. As it stands it has most of the functionality of hubski in a format which is much better suited to small screens. It can be accessed from hubski.com/m/ or by clicking the mobile link at the bottom of the page.
We would love to get feedback from everyone on hubski mobile as we continue to develop the site as we only have so many mobile devices to test on.
