Hey Product Hunt! I built APluscalc because I was frustrated with calculator websites that are cluttered with ads, require signups, and work poorly on mobile. The problem I solved: Most people need a quick calculation — BMI, mortgage payment, currency conversion — but existing tools make it harder than it needs to be. My approach: - Pure HTML/CSS/JS — no frameworks, no backend - Everything runs in your browser — zero data collection, complete privacy - 27 calculators in one place — finance, health, math, science tools - Works perfectly on mobile What took longest: Making every calculator accurate while keeping the UI clean and fast. Would love your feedback — which calculator do you find most useful? And what's missing? Try it free at apluscalc.com — no signup ever!
