Better Sleep Mobile App Light & Dark Modes

Just finished up DesignLab's UX Research & Strategy course. I wanted to fill in a few gaps in my skillset. The final project of the course is a landing page test. My hypothesis for my project was, could a bot simulate a cognitive behavioral therapy for insomnia exercise help reduce negative thought patterns before sleep. This image shows my exploration of dark-mode after receiving feedback from users regarding concerns about disruption to sleep cycles from blue-light.

A million thanks to @JJ Moi, my mentor for the course, a knowledgeable person that helped me level up my game! https://dribbble.com/jjmoi
