I'm trying a new take on the ubiquitous habit tracker app - one that tracks your daily habits but also tracks rating your day on multiple axes (enthusiasm, engagement, overall mood, etc). The idea is to correlate behaviors and outcomes in a way that provides insight into what could potentially trigger good or bad days. It's also an excuse for me to break out of backend web dev land and learn Vue.js and everything I need to know to actually build and host a web app.
