Save your contacts with privacy and discretion.
This app disguises itself as a Notes app and will appear as "Notes+" on your iPhone screen.
Upon opening the app you will be prompted with a password request. Entering your REAL password will bring you to your privately stored contacts, but you also have the option to enter your FAKE password, which will take you to a whole different screen, a Notes app, so even if someone asks you to unlock the app, you are safe!
