AdMob, which serves advertising on 7,000 mobile websites and 3,000 applications for both the iPhone and Android platforms, has released a new report that provides some excellent reference data for those in the field. You can download it here, and here’s some highlights:
- Android and iPhone users download approximately 10 new apps a month, while iPod touch owners download an average of 18 per month
- More than 90 percent of Android and iPhone OS users browse and search for apps directly on their mobile device instead of their computer
- Upgrading from the lite version was the top reason given when users were asked what drives them to purchase a paid app
- iPhone and iPod touch users are twice as likely to purchase paid apps than Android users.
- Users who regularly download paid apps spend approximately $9 on an average of five paid downloads per month
Some good news for developers pursuing a “lite” or “trial” version strategy in that it’s the main reason for purchase cited by users…. no clear reason behind the iPod Touch owners high usage stats.
