I sell the PC version to the NHS (I have 3 sites so far) but its very difficult as you ned to be an 'approved supplier', so there is a lot of paperwork to complete.
Also, I cant seem to get around the 'disconnect' between medical professionals and the student body- I think Gernot you are right- a simple poster in the student common room would work wonders.
Also, a lot of medical schools are now rolling out iPhones / iPads 'enterprise wide' & are pre-loading them with 'quality' apps, so I am looking at that option as well.
At the same time I am continuously 'stirring' the advertising in specialist publications, professional bodies, medical app review sites, medical websites, linkedin, FB, etc, etc. All in all, pushing the app is almost a full time job, never mind development!
