Online-only is a bummer

I find this app helpful, but it’s nowhere near as good as it could be for the simple fact that you cannot use it offline. That’s pretty much useless when you touch down in a new airport and don’t know where the lounge is, because in most places you won’t have wifi access until you get to the lounge. So…can’t the developers make this offline-capable? I have to take screen shots of each lounge location before I leave home for my trip as it is.
Also, I went to Muscat in Oman this last weekend and went to the lounge listed on this app, only to be told that they stopped accepted international Diners cards a month ago. Would’ve been nice if the app had updated that info.
