A super practical tool box,precise and well-designed，meets almost all the measurement needs that you can imagine。You wiil need an app like this to solve the problem,whether traveling or at home.
1. The ruler, Angle ruler, protractor function set, dynamically the Angle value.
2. The flashlight: easy open, light life.
3. The compass: the simulation of real compass, practical, accurate, beautiful, according to the direction positioning and dynamically display the current direction of mobile phone.
4. Level: the simulation of real level, can check item level.
5. Hang a picture: we can open the camera, check whether the item is visually askew, and can be learned that the deviation Angle.
6. Lead: can open the camera, in order to taken for screen background of real simulation lead to check whether the item is vertical, and display the deviation Angle.
7. Distance measurement: simple step 3, use their phones to measure around any object and the distance between you and its height.
8. A magnifying glass, through the built-in camera, let your phone into a digital magnifier, convenient to watch the small text, etc.
