mobile apps from component distributors

[owiecc]

Are there any good apps you use in your electronics work? I only know of Mouser's app. You can scan the bag's barcode to get component info. Do other distributors have similar apps? Is there "one app to rule them all" (be able to handle Digikey, RS, Mouser, Farnell, TME, ...)? Ideally I'd like to point the phone to any component bag and get a datasheet without additional clicking.
