Most timers count minutes. TimerDuel counts real focus. Two clocks share one session — focus and break — and at the end you see the truth: what percent of that hour was actually work.
Pick any length. Tap break when you drift. See your real focus rate — the single number that actually changes behavior.
More on focus timing →Stop confusing "4 hours at the library" with 4 hours of work. See how much of your session was actually studied.
For students →Run a chess-clock inside each calendar block. Your 90-minute deep work block now has a real score, not just a checkmark.
For time blockers →TimerDuel is a free online focus timer with a chess-clock twist: focus and breaks compete on a shared clock, so at the end you see your real focus rate — not just elapsed minutes. No signup, no install, works in any browser.
Yes. Set a session length (45–90 minutes is the sweet spot), hit focus when you start, tap break the moment you drift. You'll see exactly how much of your 'study session' was real focus — often a humbling number the first time.
Yes — open TimerDuel for each block on your calendar (deep work, admin, writing). The chess-clock measures real focus inside the block, so a 90-minute 'Deep Work' block on your calendar has an honest score instead of just a checkmark.
Pomodoro locks you into rigid 25/5 blocks and punishes drift. TimerDuel lets you pick any length and just measures the split between focus and break. Same discipline, no guilt loop.

Start at 25–45 minutes. Work up to 60–90 for deep work. Stop when your focus rate drops below ~60% — past that, you're burning time, not producing.
