In Hyperdimension Neptunia The App, the user can interact with characters like Neptune and Noire. The current character is displayed wearing their respective costumes and are displayed on different backgrounds. Every time the user accesses the application, the background may change.
Using the "Touch!" button, the user "interacts" with the current character and lets them hear certain dialogues from the character. Dialogues depend on the date, time, and the "Like" meter. The "Like Meter" measures a character's affection towards the user. There are three level to the "Like" meter. By interacting with a character by using the "Touch!" button even at least once a day, the "Like" meter of that character increases. Failing to interact with a character for even one day, the "Like" meter reverts back to zero.
Other types of interactions are also available, including shaking the device or tilting it in certain ways.
Certain dialogue sets can be purchased.
The application features an alarm clock feature with snooze. When the alarm sets off on the set time, the current character says a certain phrase "to get you moving."
The user can "take a picture with a character" with a camera feature. The user can change the size of the character and move them around on the background. The user can also post the picture(s) taken on a logged in Twitter account.
The camera feature is only available when a full version of a character is purchased.
