Now there are at least three — Mediquations for $1.99, Medimath, which is free until 10/12 (and will be $4.99 thereafter), and Medical Calculator (also free for a limited time). All are rated four stars at the iTunes store, and all are excellent and easy to use. As there are certain variations in the formulas included in each program, I've provided them here to make your choice easier:Mediquations (Version 5)

There are more then the above mentioned three calculators. My favorite is clearly iDocTool. As the name implies, it is not only a listing of hundres of formulas, but really a tool for daily clinical work. They included also classifications like CCS, Hunt & Hess for quick reference if you cannot remember them.
As a emergency doctor it was the thing I was looking for!
