Free Apps is More Profitable than Paid Apps [?]

Please read the interesting part of the article entitled “Missing the dazzling profit potential of free apps” that I have read:

The iPad app king of this autumn is Supercell, with “Clash of Clans” at No.1 and “Hay Day” at No.3  in the U.S. chart of highest grossing apps. “Clash of Clans” is also the No.1 iPhone revenue generator. Both games are free to download. 

“Clash of Clans” is estimated to be grossing between 160,000 – 200,000 euros each day right now. Helsinki industry sources peg the game’s initial development cost at below 140,000 euros. Supercell uses teams of five people to develop its games and the production cycle is a couple of months. What makes the creation of mobile apps so cheap is a simple trick: producers can first put out an initial version featuring 30-60 levels or 30 hours of simulation gameplay. If the app sinks, the production can be closed down. If it soars, new levels and expansion packs can be churned out at short intervals.
