Thank you for sharing this ruler app @ray147880 , this can be really useful in any way. Please see my comments below:

Pros :

• An excellent application which gives you a more convenient way to measure anything without any use of tools. You will never be using those tape measure and also you will not be measuring one by one instead it does instantly check every length,height and width of an object.
• The application itself is really easy to use where it has user friendly user interface and some clickable functions which really respond immediately as the user executes it.
• This application is both available in Google Play and App Store.

Cons :

• This is a good application which i don't see any cons in it.
