About the Calculator
A fast, clean calculator with an editable history is more useful than it sounds. The ability to click any past calculation, edit it, and instantly see the updated result eliminates the frustration of re-entering long expressions. For quick arithmetic, percentage calculations, and building on previous results without re-typing everything, this calculator is faster than reaching for a phone or desktop app.
