Army Knife for Android is designed to eliminate the need for multiple apps by combining them into one useful app.

You have ten utility-type apps residing in one place - flashlight, unit converter, timer, stopwatch, compass, bubble level, calculator, magnifying glass, mirror, and a ruler. Each tool does as it is intended. There's no space for special effects like a 3D compass, talking level, psychedelic flashlight, etc. The developer's goal was to provide a lightweight, fast and easy to use set of tools that can be accessed via one tap.

Army Knife for Android is the size of a common standalone tool like a compass, a flashlight or a magnifying glass making sure that you save space. And one nice thing is, it doesn't require network access, permission to write on your flash memory or to read your contacts.
