Stop procrastinating: TILT, time is life time, a persuasive application

As smartphone is spreading all over the world, deep in our daily life, new problems emerge like smartphone addiction and procrastination. We propose TILT (Time Is Life Time), a persuasive application that fights procrastination and helps people to decrease phone usage. TILT is based on self-monitoring, a design principle for persuasive technology. Persuasive messages are adapted to the user context to bring diversity and relevance to persuasion. A six-weeks trial is reported showing that persuasion adaptation strengthens persuasive power of self-monitoring and limits its attrition.
