Online banking app (what ever you have).  Amazon. Xfinity app. Kindle app. And I have a whole page of news.  Drudge, al jazeera, fox, 7 Boston, defense news, ynet, Jerusalem post, AP, CNN, BBC and a long war journal link.   Text+ so you can text people using a different #.   Password keeper app, Evernote, Pages.   I have an iPad so don't know how many of those will be sick on the little iPhone. If you have apple tv get the remote app
