We are looking for a logo which will be used mainly as part of our application splash screen, but will also be slightly modified and turned into an icon for use in the iTunes Store and in the iOS. The application is centred mainly around the medical physical examination which is principally done with bare hands, but also uses "tools of the trade" like a reflex hammer, tuning fork, stethoscope, sphygmomanometer, thermometer, etc. It is also a very historic tradition which is only recently under new scrutiny to become more evidence-based.
The medical school we are associated with uses a blue and gold as its official colours. These can be seen in action at http://www.nosm.ca. We are certainly not constrained by these colours, however. In fact, a colourful logo is likely to be favoured.
We'd suggest avoiding:
-the traditional doctor's bag
-blue/white dominance (a lot of other medical apps use this)
Any questions, just e-mail email@example.com. Thanks!
