I'm looking for a few good apps I can use at work. First, I need a good PDF reader I can load the state EMS protocols into. Something that can read the files without internet or cell service. It also needs a good search function and the ability to click links. Any suggestions? Also, I need a good scanner app. I just downloaded Scanner Radio but I live in a really rural area and its not surprising that the frequencies for the towns I service arent in here. Any app you can program your own frequencies into? Thanks!
