Do you have any photos or videos on your smartphone you'd like to hide from the general public? Pandora offers to put them into a password-protected box so no one can see them but you. It works exactly as advertised, but it's nowhere near as dynamic as other lockbox apps.
Though it has a name like the music-streaming app and a logo like Dropbox, it's confusingly neither. That means it can cleverly hide in your app menu without raising the eyebrow of someone looking through your phone. When you first use the app, it drops you right into the menu, which is just a button for photos and a button for videos. You don't get the chance to store a password right away. When you do find the password menu in Pandora's settings, it doesn't give you any confirmation that the password you've entered has actually been saved. You just have to exit the app and hope your password worked. If it works and lets you back in, you get the privilege of staring at the app's boring layout. Each one lets you browse your phone's entire gallery, though.
Pandora seems to be good for locking down your photos and videos, but not much else. The app isn't responsive, sports an unattractive layout, and can't hide unsavory contact history. If you just need something to hide images you don't want folks to see, this app will work.
