25 minutes of focus + 5 minutes of rest. You get notified when time is up.
Invented by Francesco Cirillo while he was in university: work for 25 minutes, take a 5-minute break — that's one "pomodoro." After every 4 pomodoros, take a longer break (15-30 minutes). The key is forcing yourself to focus on one thing at a time — no phone, no messages. A lot of people find their productivity skyrockets once they try it.
Your brain's peak focus window is roughly 20-50 minutes — research on attention and ultradian rhythms backs this up. 25 minutes is right in the sweet spot: long enough to get into flow, short enough to avoid mental fatigue. The scheduled breaks give your brain a chance to reset, so you come back sharper. There's also the deadline effect — knowing you only have 25 minutes makes you push harder instead of drifting off into "I'll get to it eventually" mode.
The classic Pomodoro is 25 minutes, but it's a guideline, not a law. If you're doing deep work — coding, writing, designing — a 45-50 minute cycle might suit you better, since it takes time to reach a flow state. On the flip side, for tasks you keep procrastinating (like filing taxes or cleaning out your inbox), try 15-20 minute rounds. "It's only 15 minutes" feels way less daunting, and getting started is usually the hardest part.
Number one: scrolling your phone during breaks. Checking Instagram or watching YouTube isn't rest — your brain is still processing information. A real break means standing up, stretching, getting water, looking out the window. Number two: not restarting the timer after an interruption. The Pomodoro rule is strict — if your focus session gets interrupted (phone call, coworker tapping your shoulder), that tomato doesn't count and you start over. Sounds harsh, but it trains you to actively protect your focus time.
