What is the 25-5 rule in Pomodoro?

It's the core of the Pomodoro Technique: 25 minutes of deep work followed by a 5-minute break. After four sessions, take a longer break. Using our 25 minute timer helps you automate this rhythm for maximum productivity.

Why use a 25 minute timer for studying?

Studying in 25-minute bursts prevents 'information overload.' It allows the brain to consolidate knowledge during the short breaks, making it the most effective method for exam preparation and long-term retention.

How does AFFiNE improve the Pomodoro experience?

Most timers are separate from your work. AFFiNE integrates the 25 minute countdown directly into your documents and whiteboards, reducing the 'context switching' that often breaks focus.

The Science of the 25-Minute Block

Developed by Francesco Cirillo, the Pomodoro Technique uses a 25-minute interval to break down complex tasks into manageable sprints. This duration is scientifically designed to balance cognitive load, preventing mental fatigue while maximizing the 'Flow State'. By using this 25 minute online timer, you are training your brain to resist distractions and commit to single-tasking.
