As for paid versions of Monument Valley, sales from the iTunes App Store far outpace sales on other marketplaces. Purchases on iOS account for 73 percent of Ustwo's $14.4 million of revenue, while only 17 percent of that total revenue came from Google Play.
Do you think it was a random factor that had it debut on iOS.
Despite far fewer devices, the Apple App Store has always made more revenue than Android. The most recent real numbers [0] I could find show this is a big difference.
I always assumed that’s why app devs roll out on iOS first.
I didn't contest the overall conclusion, but as engineers and entrepreneurs we normally have a propensity to disregard binary thinking. The numbers in your link are useful to predict expected revenue from an iOS vs an Android exclusive. The 73/17 ratio from the parent post is not, but could be misleading to someone who didn't know the app's release schedule.
