Lots of apps to use.
#1 app from our recent trip and will use for all future trips is KAYAK. You just forward your email confirmations to them and it populates in the app.
Even before the issue described below, I loved it and used it often - even though we booked nothing through Kayak.
On the last leg of our trip, we were sitting in the DTW lounge having another glass of wine. Totally oblivious to the time. An alert popped up saying our flight was boarding. Holy crap. We made the flight thanks to this app.
