freesat said they were looking at remote record.
They said nothing about phone apps, nor which OS types (and versions) might be supported. I guess we shall have to wait and see.
Think I would design such an app to be html post based then it should be easy for developers to produce apps incorporating them. A web page could them give phone free access as well.
Yes you can copy files off your foxsat via usb (format as NTFS to avoid file size limits).
