Superlatives was built using standard web technologies by me, Rylee Corradini. It's a Progressive Web App, meaning you can install it directly to your tablet/phone screen/desktop like a regular app, and it will behave more or less the same as one, and save its data in your device storage - no login needed.
Superlatives was built because I wanted a simple way to keep track of my workouts, particularly my personal bests. It's not intended to be a comprehensive workout tracker, but rather a simple way to track your progress over time. If you find it useful, I'd appreciate a shoutout on social media (I'm RyleeCoyote on Bluesky, not really much of anywhere else anymore for... reasons you can probably infer).
Trend charts are powered by Chartist.js. Most art assets are from SVG Repo, and loading indicators were generated using SVGBackgrounds.com. Almost all the art was hacked in major or minor ways by me, because SVG is keen!
