About calclu

calclu is a free collection of everyday calculators built into one calm, fast, ad-supported web app. Instead of hunting through a dozen cluttered websites, you get a single home for the numbers that matter in daily life: health tools like BMI, body fat, calorie and macro targets, water intake and sleep-cycle planning; finance tools like loan and mortgage payments, compound interest and savings goals; everyday helpers like tip and bill splitting, percentages, age, date differences and unit conversions; plus a full scientific calculator and an AI token counter for anyone working with language models.

It is built for everyone. Whether you are planning a family and tracking a pregnancy due date, a student working through trigonometry homework, a saver projecting the growth of a portfolio, or simply splitting a dinner bill, calclu gives you instant, clearly explained results. Everything updates live as you type, works on both mobile and desktop, supports multiple languages and dark mode, and saves your history so you can pick up where you left off.

calclu is built by a small independent team that believes useful tools should be fast, transparent and pleasant to use. The project is funded by clearly labelled advertising and recommended-tool placements, never by selling your data. If you have questions or feedback about the app, we would love to hear from you on the contact page.
