We've already written plenty about NimbleBit's Pocket Frogs game, because it's a great example of a successful indie freemium title.

And now NimbleBit has revealed more data about the game.

Growing lilypad

In 10 weeks on the App Store, the free game has been downloaded 3.2 million times, of which 54 percent were from the US, 8 percent from China and 7 percent from Canada.

The game was developed by two people in two months, and they spent $479.20 on marketing.

Peak daily usage has been 350,000 players, and there have been 16.5 million consumables obtained via in-app purchases.

And, bringing some charity into the equation, $3,230 has been raised for AmphibianRescue.org.
