Apps have one clear advantage. In general, a well-made app can provide a far better user experience than even the best mobile websites are capable of right now. I don’t think this is controversial.

AVERAGE INCOME FROM AN AVERAGE APP
for 200 days in the market or app store
.99cent app $1,000.00
FREE APP with admob ads $500.00 in 200 days or less depending on your apps popuplarity this would be average for an average app

However, when the top 10% of the most successful apps are removed from the data set, the numbers skew much lower, giving a far better impression of what the iPhone industry looks like for most developers. In this scenario, the average sales were 11,625 total units, averaging 44 copies/day. Approximately 23% of apps sold less than 1000 units from launch (ranging from 12 to 370 days in the App Store). Further, 56% of apps sold less than or equal to 10,000 units, while 90% sold less than 100,000 units, with the remaining 10% achieving sales of 127,000 – 3,000,000 units.
