Medical Dictionary & Guide App Reviews

So I typed in "TIA", "CVA" no results... I thought it might need the whole word or its too complicated. I then typed "arm", then "spine"... The same answer was displayed for all the terms I searched: "no results found" Using a "phone a friend" life line and having my 90y/o grandmother answer would have been more successful than this app...

I asked for definitions of words such as "cardiac" and "hematoma" and was told that there were no definitions. I tried to go into the home page and the information page to get assistance, but there was no help there. Either its too complicated to use, or is completely worthless application.
