Swiss army knife is an android app. The way swiss army knife has so many things in it this app also has many things in it like flashlight, unit converter, timer, stop watch, compass, bubble level, scientific calculator, mirror, magnifying glass, ruler.
Every cell does’nt have all these functions and if we need them we have to install them seperately but now with the help of this app you can get all these apps in a single app.
The size of this app is also very less, it’s around 300-400 kb only. Every one knows the use of each and everything in the app so I am not specifying it in detail.
Its really a useful app. Install in in your device, you may need it at any time.
