Good to know. I still like my last resort paper copies, though.For me it's TripIT, Uber and XE Currency, although I typically use ANZ's forex webpage these days as it's closer to what I'm actually getting.
Interestingly customs officers (at least in the UK) are now taking TripIT as evidence of plans. So for my last few international trips I haven't even bothered taking a paper copy of my itinerary.
I do have the Qantas QStreaming app, but I think the last time I used that was a year ago, on a 717 service which had QStreaming as it's only entertainment.
