My Take
You can get this app on your phone and get the extra features for free if you email the orginazation and tell them hat you are an educator and how you plan on using the app.
How I Use It
As a school counselor I use this very often when meeting with students individually but would also recommend that teachers practice mindfulness with their class just before a big test. It really helps students to calm their mind and stay in control of their emotions so that they can perform better.
