A Pomodoro timer that works with your focus

Flexodoro combines a classic online Pomodoro timer with a flexible mode for sessions that do not fit neatly into 25 minutes. Start immediately, stay in flow, and take a break that reflects how long you actually worked.

Focus your way

One timer for short tasks and deep work

Traditional Pomodoro timers are useful when a deadline helps you begin, but the alarm can arrive just as difficult work starts moving. Flexodoro gives you both options: predictable countdowns when you need structure and an open-ended session when protecting momentum matters more.

Classic Pomodoro presets

Choose a familiar 25-minute focus session with a 5-minute break, or use the longer 40/10 preset for deeper work.

Flexible focus sessions

Start without committing to an end time. Stop at a natural pause and let Flexodoro suggest a break based on the time you actually worked.

Distraction-free tools

Use deep-work mode, keyboard shortcuts, and optional rain, white-noise, or binaural audio without leaving the timer.

Private, useful statistics

Review completed sessions and weekly focus patterns for this device without creating an account before you can begin.

How Flexodoro works

Focus, finish, recover

Pick a focus style

Use Fixed Mode when a clear finish line helps, or Flexible Mode when an arbitrary alarm would interrupt useful momentum.

Work on one thing

Start the timer, name the task in your own notes, and give it your full attention until the session ends or you reach a natural stopping point.

Take a real break

Step away for the suggested break, then return for another round. Completed sessions are added to your statistics automatically.

Frequently asked questions

Flexodoro basics

Is Flexodoro free to use?

Yes. You can open the timer and start a fixed or flexible focus session without creating an account.

What is the difference between Fixed and Flexible Mode?

Fixed Mode counts down a chosen focus interval such as 25 or 40 minutes. Flexible Mode counts your focused time until you decide to finish, then calculates a proportional break suggestion.

Which Pomodoro length should I choose?

The 25/5 preset is a practical starting point for routine tasks. Try 40/10 for work that needs more setup or concentration. Flexible Mode is useful when your session length is unpredictable.

Does the timer keep accurate time in a background tab?

Yes. Flexodoro anchors sessions to timestamps, so the displayed time catches up correctly when the tab is hidden, the browser is throttled, or you return later.
