Where are the Aircraft Frequencies???

I love this app but I bought it mainly for the Aircraft Frequencies given I live right by LAX and VNY airports in Los Angeles, problem is that I cant find any airport/aircraft frequencies anywhere. Does anybody know where these frequencies are? Also it would be nice to be able to do a search on a scanner station by typing in the city/state or by name. Thanks
