I haven't seen a press release or anything, but someone mentioned it on Twitter last night, so I went looking and found that EBSCO has just released an iPhone app. It'll also work on an iPad, but not at full screen.
So how does it work? Log in to one of your EBSCO databasese and scroll alllllll the way down to the bottom. There you should find a new link that says EBSCOHost iPhone/iPod Touch Application:
Click that and enter an email address, and you will receive a link to the App Store (yes, you can search and find it there w/o that link), and also a link to click that will marry the app to your specific institution. Very seamless and straightforward process. The only glitch is that the authentication code seems to work for anyone; I forwarded it to some folks in the States who corroborated that they were now seen as University of Calgary users.
I do notice that part of what that authorization does is include my institution's ezproxy prefix, so I suspect at some point it's still secure enough. Oh, and I do see in the Help file within the app that you'll need to regenerate that code every 9 months. Even w/o a code, the app gives you an option to search as a guest. You're limited to searching GreenFILE at that point.
There's just a basic search box, no option for "advanced search". Limiters such as Full Text, Peer Reviewed, date etc, appear under the Settings tab, but all the way at the bottom of the screen, below the list of databases. All databases appear to be checked by default.
The app helpfully remembers recent searches, and you can save both searches and articles for later viewing. Individual articles can be emailed, with full text, though I don't see an option to select multiple records. PDFs are available within the app. Results can be sorted by date or relevance.
Here are some screenshots for you. Overall it's a pretty nice app - well done EBSCOHost!
