Why we built it
Most calculator sites are slow, cluttered and painful on a phone. PercentNow was built to be the opposite:
Fast — plain HTML, no frameworks, results as you type.
Clean — one calculator per page, nothing in the way.
Mobile-friendly — designed for the phone in your hand at the store.
Dark mode — follows your system setting automatically.
