What we build
Every tool on this site does one job well: percentages, age math, loan EMIs, BMI, discounts, tips, unit and currency conversion, word counts, text case changes, QR codes, passwords and date differences. Each tool page includes a how-to guide and answers to common questions.
Privacy by design
Calculations happen locally on your device. The tools themselves don't upload your inputs or require accounts. Like most free websites, we may show ads (see our Privacy Policy).
Accuracy
Tools use standard formulas and are intended for everyday estimates. Financial, health and currency outputs are informational — not professional advice. Currency rates shown are indicative reference rates.
