I make money only from advertisements. Suggestions are InMobi and Google Ads. However, Google ads are not so good. That's at least my opinion.
Can you explain about 1.000 download....$5-20 more detail?yes i think the best way in android to make $ is to offer your app as free and have IAPs, or a premium full version(but that opens to pirated sideloads, heck ive seen mods of the IAPs in full sheesh)
gameloft and EA have moved to this model, Zynga made it very popular, just look at a hypothetical scenario
1,000 downloads.
1 dude spends $900 on IAPs
10 dudes $50 max
50 $20-50
70 $5-20
the 870 rest less than $5 or play for free and grind through but you made a good RIO on just one user, Ive seen people spend a sh*tton of $$ on freetoplay games, look at the high earners on the play store, most are *free* but have IAPs.
I'm using in-app purchases in a live wallpaper app, so users can buy more themes. Been doing around $2 per day on average, since it was released (around 1 month ago). Not running to the Ferrari dealer yet...
