I just renewed my pro subscription to this app. I really loved it when it first came out - however since concur aquired it I see the app not improving as much as it should for $50/year. Also some tasks are very difficult - like adding flights manually - or even trying to move a flight to a different trip. They will have to do a lot more. If you are a frequently flyer and use airline apps too - there is a lot of duplication.
I dont think the pro really gives you much other than adding people to your track you.
I have yet to be able to use any of the "free" or "saving me money" features that they offer.
