Tip: New to focused work? Start with the Pomodoro timer - It's the friendliest way to feel the difference a simple countdown makes.
A–Z of timing, focus & training terms
- Pomodoro Technique
- A time-management method that breaks work into 25-minute focus blocks separated by 5-minute breaks, with a longer break after four rounds. Run it automatically with the Pomodoro timer, or read the full Pomodoro Technique guide.
- Tabata
- A high-intensity interval format: 20 seconds of all-out work, 10 seconds of rest, repeated for 8 rounds (four minutes). Try the preset Tabata timer.
- HIIT
- High-Intensity Interval Training - Alternating short, hard efforts with recovery. Time your rounds with the interval timer or read the HIIT and interval training guide.
- EMOM
- Every Minute On the Minute - You start a set piece of work at the top of each minute and rest with whatever time is left. An interval timer on loop keeps it honest.
- AMRAP
- As Many Rounds (or Reps) As Possible in a fixed time. Set a workout timer and go until it rings.
- Interval timer
- A timer that counts down a set period and repeats, for work-and-rest training. See the interval timer.
- Timeboxing
- Giving a task a fixed, pre-decided slot of time so it can't expand to fill your day. The idea behind time blocking.
- Time blocking
- Planning your day as a series of dedicated blocks, each with one job. Learn how in Time Blocking.
- Countdown timer
- A timer that counts down from a set duration to zero and alerts you - The core of timer.now.
- Stopwatch
- A timer that counts up from zero to measure elapsed time, usually with laps. Use the online stopwatch.
- Split time
- On a stopwatch, the time recorded for a single segment (lap) rather than the total. The stopwatch records both.
- Parkinson’s Law
- The adage that "work expands to fill the time available for its completion"- which is why a deadline helps. More in how the clock shapes decisions.
- Deep work
- Focused, distraction-free work on a cognitively demanding task. A study timer or Pomodoro timer helps protect it.
- Focus block
- A single, bounded stretch of concentration on one task. See the best block lengths for studying.
- Power nap
- A short sleep of roughly 10–30 minutes taken to restore alertness without grogginess. Time one with the sleep timer.
- Box breathing
- A calming technique: breathe in, hold, out, and hold again for equal counts (often four seconds each). Time it with the meditation timer.
- Work-to-rest ratio
- The proportion of effort to recovery in interval training - 2:1 in Tabata (20s/10s), for example. Set yours on the interval timer.
- Ultradian rhythm
- A natural body cycle shorter than a day; many people focus well in ~90-minute ultradian waves. See study timer lengths.
