Tablet apps are an increasing interest for developers. The iPad already supports over 375 thousand tablet optimized apps, and Android and Windows are beginning to pick up speed.
A recent ABI research report suggests the tablet app market is becoming increasingly more lucrative.
An interesting aspect of the mobile app market is revenues generated by smartphone versus tablets. Thus far, app revenues generated from smartphones have significantly dwarfed app revenues from tablets. However, tablet revenues are quickly catching up and it is projected tablet app revenues will overtake smartphones by 2017. The inclination for tablet users to pay more for apps than their smartphones because of the larger screen size and better user experience for gaming and reading are the primary drivers.
In an App Accelerator Survey, 84% of the 6,046 app developers polled planned to make a smartphone app in six months, and 81% planned to make a tablet app.Also, there is a big shift toward enterprise apps. In Q4 2010, 70.7% of polled developers said they were focusing on or developing a consumer app. In Q2 2013 that number fell to 57.2%. Conversely, in Q4 2010 29.34% of developers were focusing on or developing enterprise apps. In Q2 2013, that number grew to 42.7%.
The report also hints at the possibility of there being a third major player in the mobile space. There is also much interest in cross platform apps; 90% of surveyed developers said they write apps for multiple OS'.
