I built Simplicalcs because most free calculator sites are cluttered, untrustworthy, or make you wade through ads before you can use the tool. I wanted something that just works — fast, clean, no account required. It started with one or two tools and has grown to cover finance (VAT, salary, mortgage), health (BMI, BMR), maths (scientific, equation solver, statistics), electrical engineering, and travel (Schengen day tracker). Everything runs in the browser — no server, no data collected. Would love feedback on which tools people find most useful, and what's missing.
