Thread: What pharmaceutical PDA program do you find the most useful in your practice?

My boyfriend is a pharmacy student and I'm trying to find a good program to put on his PDA that I got him for Valentine's day. what program/s have you found the be the most useful, or what would you recommend for a pharmacy school student? And i would really appreciate actual pharmacists or current pharmacy students only seriously answering this question. thanks!

We're American. I don't know if that makes any difference on the program. I'm not very familiar with pharmacy stuff, so I wasn't sure if metric was used or what.
