The Google Play Store doesn't do a very good job of separating Phone apps from Tablet apps. You literally have to search these tablet specific apps out for yourself. Not anymore thanks to the Tablified Market which has recently seen an update. Tablified is a large highly organized database of tablet specific apps. The update includes a new UI which makes it look more like the new playstore, the app uses roboto font, app descriptions and screenshots will autoupdate when updated in the play store, better portrait mode for 10" devices, higher res icons and screenshots, and lots of new apps and games. Check out this app for the best tablet experience.
