NOTE: AVOID THIS APP AND ALL DEVICES THAT USE IT! Why can’t someone write an app that will read various makes of usb flash drive for iPhone??? ALL OF THEM seem to have this proprietary thing so if you have 17 makes of usb flash drive, you have to have 17 mostly worthless and horrible apps like this one!If I could give it zero stars, I would. Five words: NOT MAC OR IPHONE FRIENDLY! 1) Get out your stone knives and bearskins. Alphabetic sort function DOESN’t work if you use non-8.3 fileNames. 2) Interface will not rotate to phone landscape orientation, though it will play videos in landscape view. 3) Starts playing video again shortly after you pause the video if you don’t either eject the usb drive or quit the app. So, if you’re watching a movie, and pause to use the bathroom or get a soda, you come back and find that the movie has been playing and you’ve missed part of it. Then … 4) You can’t resume where you left off because it’s impossible to move the progress bar to anywhere near where you wanted to start watching again. 5) Ugly interface. End rant.P.S. I tried the other 2 “Y-Disk apps — HD & Pro — they wouldn’t even recognize the Y-Disk usb external. Utterly worthless!!
