🕰️ History

I originally kept the code to myself, but things took a turn when I replied to a tweet that was already going viral. People started asking me for the repo, and since I had shared a screenshot of the code straight from a WhatsApp text (with the worst font possible for this purpose), I figured it was time to share it properly. Back then(2 years ago), I didn’t have a repo, so I threw together a basic one just to get the code out there.

Now, after two years, I decided to give it a proper update with a better UI and more detailed info.
