About Pomodoro Timer
The Pomodoro Technique breaks work into focused intervals separated by short breaks — traditionally 25 minutes of work and 5 of rest, with a longer break every fourth round. The timer advances through the cycle automatically and keeps count of the sessions you finish.
How to use it
- Adjust the focus, short break and long break lengths if you want.
- Press Start and work until the alert sounds.
- Take the break the timer moves you into.
- After four rounds you get a long break automatically.
Frequently asked questions
Why 25 minutes?
It is long enough for meaningful work and short enough that starting feels easy — which is the real barrier for most people. The length is a convention, not a rule; adjust it to suit your task.
Does the timer run when the tab is hidden?
Yes. It tracks wall-clock time rather than counting intervals, so background throttling cannot make it drift.
Are my sessions saved?
Your settings and today's session count are kept in your browser's local storage. They stay on your device and are never sent anywhere.

A Systematic Investment Plan is a standing instruction to put a fixed amount into a mutual fund on the same date each month. That is the whole idea. It is not a product you buy, not an asset class, and not a scheme with a guaranteed rate — it is a schedule. The returns come from whatever the underlying fund holds.

BMI Calculator guide
Body Mass Index is weight in kilograms divided by height in metres squared. That is the whole calculation. It was devised in the 1830s by the Belgian statistician Adolphe Quetelet, who was explicitly describing populations rather than assessing individuals — a distinction that matters enormously and gets lost constantly.

Almost every percentage problem is one of four shapes. Knowing which one you are looking at is most of the work, because each has a different formula and mixing them up is where the wrong answers come from.
