I'm currently working on the next version of NeuroPub, which will be released for both iPhone and iPad as a universal app. The developer version is working for iPhone and it will be released in good time before the Human Brain Mapping (HBM) 2013 conference in Seattle.
The new version will be presented as a poster at the conference on Monday, June 17. The poster number is #1444 (NeuroPub Visualizer for iPad and iPhone - Current Status and Development). If you are going HBM 2013 then please come to the poster session if you want to discuss NeuroPub. I would love to get your feedback! :-)
