According to 148Apps.biz, who keeps a running tab on app store metrics, Apple’s U.S. App Store passed the quarter million mark on Friday, just two years and 49 days after it opened to the world. As of Saturday morning, there were 251,007 applications from 50,304 publishers available for download for the iPhone, iPad or iPod touch. AppShopper.com, which keeps a similar list, has the total pegged at 253,777 apps, including 24,334 for the iPad.
A break-down by category shows that books (with 17%) have now overtaken games (14%) and entertainment (11%) for the number one spot with 43,976 total active apps. Roughly 70% of the offerings on Apple’s store are paid apps, while the Android Market, by contrast, has 64% that are free. Other interesting tidbits include the average app approval delay of 6.79 days with a maximum delay of 52 days.
The mobile app ecosystem continues to balloon, but when will we see a saturation point? With all the current app stores, there’s roughly 500,000+ total apps on the market for consumers. A developer submitting their app needs to be highly unique to stand out in all that noise. Still, Apple’s App Store continues to dominate, and it’s especially timely as Apple prepares to make an announcement on Wednesday that’s rumored to include new iPod Touch devices.
