Hey Product Hunt We built Zen Calculator because we kept hitting the same wall — calculator sites online were either bloated with ads, confusing to use, or gave inconsistent results. So we set out to build something simple: fast, accurate, mobile-friendly calculators for real situations, from schoolwork to gaming to home improvement. Would love your feedback — what calculator do you wish existed that we haven't built yet?
