What is the secret to happiness? Turns out, there's an app for that.
Five years ago, Matt Killingsworth built an app, Track Your Happiness, which prompts users to report their feelings in real time. Here's how it works: users receive a text or email asking to record what they are doing and how they are feeling at that moment. The app records these responses over time and creates a personalized "Happiness Report" which details what activities are associated with greater happiness. In addition to providing the individual, personalized report, the app collects data that fuels Killingsworth's research at the Robert Wood Johnson Foundation. To date, over 35,000 people have participated in the study.
