I recently came across a very interesting application called Genius Medical Diary by Gurparit Chand. It stood out to me, seeing as I have not really seen an app quite like this before. The app acts as a database for all of your pertinent medical information. It stores such data as name, social security number, blood type, medications, diseases/conditions, immunizations, contact numbers, emergency contacts, and insurance information. With this app, you can store as many medical profiles as you wish, making it great for qucik access to your entire family's medical info. The application also features backup/restore to device, which is nice with any app. Genius Medical Diary is on sale for $1.99 until March 1st for all Blackberrys running OS 4.5+. You can also try their free version BerryMed, however it does lack in features when comparing to Genius Medical Diary, which is to be expected.
