IT Works is an IT asset management native iPhone application. It lets you store and manage detailed information about computers, devices, and users, using AES-128 encryption from the system-provided frameworks for storing sensitive data such as passwords. A Master Password is set up on first run that both protects access to your information and encrypts your data. When you want to add new information, or edit/delete existing records you must ‘unlock’ the Application using the Master Password, which will also let you view your passwords in clear text.
