Phantom Secure

"The purpose of the app is to store information on your phone that you would like no one to see or know about. There are apps out there that appear as a vault, hidden calculator etc. That you require a password for you to access, the problem with this is that people know you’re hiding something because you have an app that requires security passwords and will be caught out and may be forced to put in the password. I would like to go a step further and create a two-step security where the first step requires you to write a certain “phrase” anywhere on your phone, which reveals the app on your phone, then a secondary password which you put in to access the actual app. From there you can access anything you have stored in there…eg photos, notes, videos, contacts, messages etc…
