This document describes an app called LIM (Live Interest Meter) that aims to help users improve their presentation skills through reflection on audience feedback. The app captures feedback during presentations using polls and questions, then quantifies and visualizes it to facilitate reflective learning. It was inspired by "Quantified Self" approaches. The document outlines the use case, hands-on steps to use LIM, its various dashboard and feedback features, results from a small evaluation study where it helped participants focus on improving aspects like speed and comprehension, and conclusions that regular use and further context could enhance reflective learning.
