A fast three-step workflow
How to use the pomodoro timer
- 1
Enter the known information
Add only the values or source text the calculation needs. Useful examples and safe defaults are already selected.
- 2

Use the extra controls to match your real task instead of accepting a hidden one-size-fits-all assumption.
- 3
Review the complete result
Check the main answer, supporting values and method before copying, downloading or acting on the result.
What makes this tool more useful
Run a focus timer without installing an app. Change every interval, pause safely and track completed focus cycles in the current tab.
How the calculation works
The timer tracks a target timestamp instead of subtracting one second per interval, reducing drift when the browser briefly slows down.
Use timed focus blocks for writing, coding, study sessions or administrative work.
Private, fast and mobile-ready
The workspace runs with browser JavaScript and does not submit entered values to a Rantey calculation endpoint. Controls use readable labels, large touch targets and responsive result panels for narrow screens.
