Islamic tools (Zakat, inheritance, Hijri dates), personal finance (loans, savings, VAT, end of service), health (BMI, calories, due date) and everyday tools (GPA, age, unit conversion). No sign-up and no clutter: everything runs instantly in your browser, and your numbers never leave your device. Each tool explains how it calculates, and new tools are added regularly.
