Yeah, saw that article earlier on reddit. Would be pleasantly surprised if those estimates are accurate. Sensor Tower is pretty reputable though, so I don't know.
The article is making 10M installs sound small (and it is small in mobile standard I suppose) but for a niche mobile game like Heroes, I still find it hard to believe. Like, you are saying millions of people are playing this stupid game with me regularly? No way in hell. I don't know a single person IRL that plays FE:H. lol
10 dollars per install sounds about right though, thanks whales and dolphins! Sucks that SMR couldn't do the same.
Now, with all that money, Echoes 2: Rebirth of Grannvale when?
