Software applications can fall under four postures - Sovereign, Transient, Daemon, and Parasitic/Auxiliary
Which of these categories do mobile applications like Wunderlist, Facebook app, Evernote fall under? (My guess is Parasitic)
Apart from mobile games, are there mobile apps that have sovereign posture? I am not looking for apps like Wordpress or Medium where the user has to painstakingly type content. I want to know sovereign apps that take advantage of the mobile form factor. Autodesk Sketchbook is an example for tablets. I need some similar apps for mobile phones - displays around 4 to 5.5 inches.
Edit: By sovereign, here I mean an app that takes user's attention for extensive time periods - may be an hour or more. In desktop, applications like Eclipse, Photoshop, MS Word are considered sovereign. They take the entire screen real estate, but my main focus is on how long the app is used in one session. Similarly, most mobile apps occupy the entire screen, but I need examples where an app is used close to an hour or more to reach user goals in one session. I need examples of productive sovereign apps.
