The document describes a wearable device called The Path to Tranquility that uses sensors and connects to a phone app via Bluetooth to record times and places of stress both offline and online. It took less than an hour to develop the software and half an hour to develop the hardware, although delivery takes over 3 weeks. Potential improvements discussed include predictive avoidance of stressful situations, support for multiple users, statistics and reports, a smaller physical unit, and integrating it into clothing.
