I created an application that helps current and former victims of domestic violence. The end user I chose was the victim.
I feel that an application is both discreet and ubiquitous. Sensitive information can be encrypted, and access can be made exclusive.
The app provides an immediate, 24 hour connection to support systems, in this case: law enforcement and fellow survivors.
This app was designed for dual functionality on both Android and iOS interfaces. The design style I went for was a bit more conservative and more typical to a standard application, rather than something experiemental.
