I use TP Lines but admit I've never used at Universal because I haven't been to Universal since they started offering it, but my SiL family did 2 weeks ago and stated it worked like a charm. I use it at DLR all the time and find it to be more accurate than any other app for current wait times. I find DLR posts inaccurate wait times to handle movement of crowds (post 50 minutes for Alice, when it's really 25 to discourage people from getting in that line and go somewhere else). You can get the posted times with this app without paying (same info you would get with Universal app or user inputted apps), but if you want their expected time, which is generally more accurate, then you do have to pay, but it's pretty minimal, and you get touring plans with it.
