The digital version should’ve have been specific to either iOS, MAC, iOS, Android OR PC. I thought I was receiving 114 pages of tips, but unfortunately almost 30 of those pages were specific to android users and I do NOT have any android devices. I won’t even mention the ink I wasted when I printed those pages that are useless to me (because I didn’t know some pages were device specific). I gave it two stars because I pretty much just learned 2 things from the entire book. Very disappointed. Not worth the money.
