Yes I have the paid version with all features. But it looks like the add-ons have been split into a few different in app purchases. Just taking a quick look at the free version, it appears to support transfer to local machines. If you want the auto transfer feature, that’s a paid feature.

Syncthing is good free alternative as well. I use it primarily for documents between devices, I just haven’t tried it with photos since I already have the PhotoSync app configured.
