Scientific Calculator
The Scientific Calculator handles everything from basic arithmetic to advanced math — trigonometric functions, logarithms, exponents, factorials, and more. It supports both standard and scientific notation.Percentage Calculator
The Percentage Calculator solves the three most common percentage problems:- What is X% of Y? — "What is 15% of 200?" → 30
- X is what % of Y? — "45 is what % of 200?" → 22.5%
- Percentage change — "From 80 to 100?" → 25% increase
BMI Calculator
The BMI Calculator calculates Body Mass Index from height and weight. It supports both metric (kg/cm) and imperial (lbs/inches) and shows where you fall on the BMI scale.| BMI Range | Category |
|---|---|
| Below 18.5 | Underweight |
| 18.5 - 24.9 | Normal weight |

Countdown Timer
The Countdown Timer counts down to any future date or duration. Use it for meeting deadlines, cooking timers, exam countdowns, or event launches. Features audio alerts and full-screen mode.Stopwatch

The Date Difference Calculator finds the exact number of days, weeks, months, and years between any two dates. How many days until vacation? How long since a particular event? This tool answers both. Productivity Hack: Use the Countdown Timer for the Pomodoro Technique — 25 minutes of focused work followed by a 5-minute break. It's one of the most effective productivity methods for deep work.
