New Canalys’ App Interrogator research highlights one of the deficiencies of the Android ecosystem: limited availability of high-quality, tablet-optimized apps in the Google Play store. Of the top 50 paid and free iPad apps in Apple’s US App Store, based on aggregated daily rankings in the first half of 2013, 30% were absent from Google Play. A further 18% were available, but not optimized for tablet users, offering no more than a smart phone app blown up to the size of a tablet screen.

Just 52% of apps had Android versions both available through Google Play and optimized (if only a little) for tablet use. “Quite simply, building high-quality app experiences for Android tablets has not been among many developers’ top priorities to date,” said Canalys Senior Analyst Tim Shepherd in a statement. “That there are over 375,000 apps in the Apple App Store that are designed with iPad users in mind, versus just a fraction of this – in the low tens of thousands – available through Google Play, underscores this point.”

Google needs to do more to encourage greater numbers of developers to invest in delivering high-quality Android tablet apps quickly, else it risks disappointing consumers with weak app experiences in the short term. The 52% of top apps available through Google Play and optimized for tablets also includes six titles that appear as top paid titles on iOS, but are only available as free, ad-supported versions on Android. “While nominally free, set against a paid version of the app, ad-supported offerings typically deliver a poorer and often more limited user experience, sometimes taking a considerable toll on device battery life and often subjecting users to unskippable videos or other unpopular intrusions,” said Canalys Analyst Daniel Matte in a statement.

“To take the Play ecosystem to the next level, Google needs more than just a large addressable base of devices. App developers need to see clear potential to build robust and sustainable business models around apps built for the platform, so increasing monetization potential must be a priority,” said Shepherd. “And for tablet apps in particular, Google should go further with changes to the Play store to ensure more rigorously managed, high-quality, optimized experiences are highlighted, to the benefit of consumers, and to reward those developers who invest the time and resources in building them with improved discoverability.”
