Indie developers Semi Secret and Backflip Studios speak out.
iPhone is looming large at this week's Game Developers Conference in San Francisco, with indie firms Semi Secret and Backflip Studios dishing stats on the success of their games on the App Store.
Semi Secret's Canabalt has sold 115,000 downloads in five months, which with its $2.99 price point means revenues of more than $240,000 for the developer.
Not bad for a game originally written as a web Flash game in five days, which was then ported to iPhone in a couple of weeks.
Meanwhile, Backflip Studios has generated $2.5 million of revenues in the last nine and a half months, based on 22 million paid and free downloads of its games.
That includes $1 million from in-game advertising in the last six months alone, fuelled by the 17 million downloads of its free game Paper Toss.
Just in December, the company made $379,000 from advertising, and $89,000 from paid game sales.
Backflip boss Julian Farrior told the GDC audience that the company works with several ad networks, including AdMob and Quattro Wireless, while also using its advertising slots to promote its own paid games.
