Most embeddable widgets are surveillance with rounded corners.
You paste one script tag, it opens a socket back to someone else's server, drops analytics, fingerprints the page, and turns your article into their funnel.
I wanted the opposite.
I had built a small screen-time calculator for an iPhone side project. You enter daily phone hours, how much of that time you'd actually want back, and your age. It returns the number not just as hours per year, but as waking years of the life you have left.
The surprising part was not the maths. The surprising part was that the calculator itself was the first marketing asset I had built that people might reasonably link to.
