The purpose of this mobile app is for the Pennsylvania State Facility Engineering Institute's (PSFEI) Visible Emissions Training Program testing, also known as Smoke School. The app allows smoke school students to submit their observed plume opacity through their mobile device. The app allows the course instructor to submit the answer key of all the plume opacities and evaluate the student answers. The app also provides reporting and charting functionality for the instructor to analyze student test results and display the pass/fail result to the students.
