No, the app is targeted at Doctors and Medical Students. Most of the cases use technical terms and require medical knowledge in order to be solved properly.
The case displayed on the blog is admittedly very simple - mainly because it is a 'demo case' for users to become familiar with how the app works. The remainder range from easy to quite challenging.
The app is almost ready - at the moment a panel of consultants (attending physicians / surgeons) is going through them to make sure that all details are correct. Once this is done, it will be submitted to the app store.
Would you like to be a beta-tester ? Please let me know.
P.S. I am a doctor :)
