Just responding to this comment because all the comments below it seem to be tone deaf and are just complaining about Governments.

BAS (and all tax documents) can still be submitted via a Tax Agent or via Mail. There is no "lock in". Chances are if you own a computer, you own an android and an apple phone, who cares.

Mountain meet molehill.
