The Smart Tools: Utilities Toolbox app is a one-stop solution for your utility needs. This toolbox app offers you the best and most comprehensive set of tools for measuring, comparing, and more. You will not need to download another app or plug-in to your PC. All of the tools are right on your Android phone and can be used on the go. You can measure length, angle, distance, height, and more using the built-in sensors. You can also use the built-in compass to determine the direction. The app also includes a ruler, a protractor, and a speedometer to measure speed.

You will also get access to a range of other utilities. The app includes a powerful magnifying glass to help you see things that are difficult to see with the naked eye. It also includes a bubble level, laser level, and dB level to help you get a precise angle or level measurement. You can use the app to measure your own property or the property of someone else. You can also use it to find out how level your floor is, whether your roof is flat or not, and whether it is horizontal or vertical.

You can also use the app to compare measurements.
