I just wanted to throw this app out there. It is available on iPhone and Android and appears to offer a ton of information for just $20!!! Not to mention continuous(and free) weekly updates. It has been mentioned in passing on here as I did a search. But I thought it deserved it's own thread. For the folks that use a tablet, this seems to be the best out there.
Obviously, no connection to the product. I just thought it represents a lot of value. I mean a radar overlay???!!!! Pretty nice!
