Despite the hype, there is sporadic use of app stores outside the Apple and Android platforms. Our survey of 400+ mobile developers found that only four percent of Java respondents used App Stores as their primary channel to market. Windows Phone and mobile web developers find app stores little more relevant, with fewer than 10 percent of such respondents using one as a primary channel for taking applications to market.
This contrasts completely with platforms that have ‘native’ app stores. Over 95 percent of iPhone respondents use the Apple App Store as their primary channel, while the percentage of Android respondents using Android Market is just below 90.
In terms of the incumbent mobile platforms, around 75 percent of Symbian respondents that use app stores, use the Nokia Ovi Store. The significant number (20-25 percent) of Symbian developers who also use iPhone and Android app stores reveals the brain-drain that is taking place towards these newer platforms. This is a particularly critical migration of developer mindshare, considering that the Symbian platform is the hardest to master. Thus, the size of developer investments on Symbian being written off is substantial.

Besides the growth of apps, app stores are the cornerstone of another major transformation that has taken place in the mobile industry: the mass-market use of mobile as the next marketing channel beyond the Internet. We would argue that it was app stores that triggered the influx of apps – not the open source nature of Android, or the consumer sex appeal of the iPhone.
App stores triggered the sheer growth in app numbers and diversity that led to the cliché, “there’s an app for that”. Another cliché, “the screen is the app,” tells the other half of the story. Combined, the app store and touchscreen were the two essential ingredients behind mobile apps as the next mass-market channel beyond the Internet. These two ingredients inspired just about every media and service company to commission companion or revenue-driven apps as extensions to their traditional online channels. In effect, this phenomenon fueled the app economy, even beyond what app store numbers alone suggest.
Speeding up time to market
App stores have revolutionised time to market for applications. To research exactly how radically the time to market for applications has changed since the introduction of app stores, we analysed two parameters:
- the time to shelf, i.e. how long it takes from submitting an application to that application being available for purchase
- the time to payment, i.e. the length of time between an application being sold and the proceeds reaching the developer’s bank account
Our findings show that app stores have reduced the average time-to-shelf by two thirds: from 68 days across traditional channels, to 22 days via an app store. These traditional channels have been suffering from long, proprietary and fragmented processes of application certification, approval, targeting and pricing, all of which need to be established via one-to-one commercial agreements. Moreover, app stores have reduced the time-to-payment by more than half; from 82 days on average in the case of traditional channels, to 36 days on average with app stores.
