Another answer to the burning “how much money are iPhone app developers really bringing in from advertising” question. Irvine, Calif.-based MobilityWare says its ad-supported Word Warp game is averaging just over $10,000 in revenue per month.
The game launched in September 2008 — and we’re in the process of confirming whether the revenue estimate is accurate for the past 10 months — but if it is, then Word Wrap has generated roughly $100,000 in ad revenue since last year. Not bad for an app that marketing director David Yonamine told TheAppleBlog cost in the “mid-five figures” to develop.
Greystripe serves the ads, which show up in-between levels; the startup said CPMs hovered in the $1.91 range. MobilityWare offers a 99-cent version of the game, but a majority of users (over 1.5 million people) have chosen to download the free one and deal with the ads. Yonamine told TheAppleBlog that the company funnels some of the ad revenues back into development to help keep the game updated (and popular).
What’s not as clear is how much money the startup had to spend promoting the app in the past — as companies like Adwhirl have shown that it can be quite expensive to get an app seen by the masses in the first place.
