So you are well aware of the booming and highly lucrative tablet PC app development market, and perhaps you have one or more ideas for a new mobile app, but you have no idea how to develop your own app, how much it will cost or where to get started. If you can relate to this then I urge you to continue reading!
First of all, before I get started with providing a helpful list of tablet PC app development resources, please allow me to present you with a few fun facts and statistics about the mind boggling growth of the tablet computer app development industry.
Tablet Computer Mobile App Market Statistics
The very first app became available for smartphones back in 2008, to be more exact apps for the iPhone from the newly launched Apple App Store. By the end of 2008 there were roughly 10,000 apps developed and available to consumers. These numbers continued to grow at a rapid rate and of course exploded even more with the introduction of the iPad and Android tablets.
Fast forward to today, less than 3 years later, and the number of available iOS apps has increased to over a whopping 500,000 in total. Not to mention, the amount of Android tablet apps is also booming. By the end of 2010 the iOS app market became a $6.8 billion dollar industry. At the rate the app market is growing it’s expected that by the year 2013 apps will generate an annual amount of nearly $30 billion dollars in revenue which is quite mind boggling to say the least.
It’s projected that 20 billion iOS apps will be downloaded this year alone, give or take. Estimated revenue growth mentioned above is for iOS app purchases only and does not include the expected $860+ million in-app ad revenue that is likely to be the case by 2014.
