Rating: 4.3
This is the app we talked about in the intro of our 9 iPhone and Android secret messaging apps to hide text from girlfriend article. When you open the app, it will look like just another calculator. But, after you enter the correct password, a whole new world will open. Your texts will be secure and you won’t have to worry about someone suddenly blowing your cover. The app is entirely customizable and allows you to hide texts, pictures and call logs. There is a similar app for iPhone, but that one allows you only to hide your videos and photos.
