Bit of extra faff to get it working if you're not rooted (you have to plug in your phone and install the app on your computer, rooted you don't need that) and you have to pay for the "back up specific app" feature. But you can always use it then get a refund.
I used it successfully to transfer my game save from my phone to my windows android emulator (Nox App Player).
