hey - what's the difference between chromatic and [i forget the name of the other type of tuner]?

i have a program on my computer that acts as a tuner for my electric when i plug it in, but it isn't as precise as it could be. also, i then have to tune my acoustic with my electric.

should i get a tuner? what's the best kind - the one with the needle, or the LED displays?

Thanks for your help, guys.
