Smart Tools for Your Android Device
Smart Tools Co. is a developer of handy Android apps for measuring things. Some of the free apps that they offer include Smart Measure, Sound Meter, Vibration Meter, Speed Â Gun, and Smart Protractor. Smart Tools also offers pro versions of those apps.
I’m not a mathematics teacher and admittedly my geometry skills are rusty, but when I watched the videos of Smart Measure and Smart Protractor in action (videos below) I couldn’t help but think that there has to be a math lesson lying in wait with these apps.
