Maybe this is not so much a review of the app but of their check in policy. I feel it is extortion to REQUIRE a credit card on file AND pre-authorization to charge it. I am on this flight solely because my favorite discount airline doesn't have a nonstop option on this particular travel date. The ticket cost is more than double (even with United's "Basic Economy" tier. I'm ok if you give me the option to to pre authorize but not that I MUST pre authorize.

New problem found: Multi-city trip doesn't work. When you try to add a 2nd flight to the trip, it just duplicates the 1st leg. Why does it make me type my password every time I try to use the app? When I start up the app it shows my name, account number, and miles, so I think I'm logged in but then when I go to search flights it makes me type my password. Isn't one of the points of these apps to be that you're always logged in? Also why is the seat map oriented left to right when our phones

Just downloaded for an upcoming flight, as recommended by a United email about my trip. However, it's completely unusable. I managed to sign in, but now the app loads up for a second, and then immediately crashes. I checked for updates and restarted my phone. It still crashes every time. It's useless to me right now. I like the idea of what the app has to offer, but can't use any of it so it kinda defeats the whole purpose. It might be helpful, but it's gotta work first.
