Daily UI Challenge #018 -- Analytics Chart

My deskmate is making a program and wearable devices that can detect the stress level based on heart rate and other parameters. I like this project because it can help people, thus I made this interface in this daily challenge.

The target user is factory workers whose job is to handle machines. As a result, they may be mentally overloaded and get fatigue easily. This program can help them monitor their own stress level, so that when they are under great pressure, it can remind them to take a break for their health.
