Not your parent poster, but I appreciated that Photosync was a one time purchase, and developed by a German company. Worth it to have a solid backup tool that can push to a Samba share.

I am already using an iPhone, so those things do not typically enter my calculus for selecting apps. I don't like it, but the alternative is using Android, so it's the tradeoff I am making. I know that isn't a very good answer.
