I've seen good airline apps and bad airline apps. The good ones allow you to do things like checking your own bags and dropping off bags without talking to anyone. The bad ones simply are slow and have missing features: you may be able to buy a ticket but changing it requires calling a number. (Of course if you are the type to prefer human customer service, these won't appeal to you.)
