No one seems to mention the obvious(?) considerations:
"Provide additional convenience with an iPhone app." vs. "Encourage people in our ecosystem/sphere of influence to use Android devices."
After all people who use GA run websites and people who run websites might also make Apps. If their primary device(s) are Android, they might think Android-first when it comes to Apps.
Some of us who use GA write/run iOS apps and use iPhones/iPads as primary devices. An iPhone app for monitoring GA provides additional convenience. Encouraging us (thru not providing a native iOS app for GA) to use Android devices is encouraging us to use something other than GA (and yes, there are other options). Seems pretty obvious to consider.
