Why Fifteen Minutes Works So Well

Fifteen minutes is long enough to make real progress and short enough that starting doesn't feel like a big commitment. That makes it one of the most useful blocks for anyone who finds long sessions hard to begin — including many people with ADHD, who often do better with shorter sprints.

• Study sprints — try a 15/3 rhythm: fifteen minutes of focused study, three minutes off. It's a gentler version of the classic 25/5 Pomodoro.
• Homework blocks for kids — a clear, finite block makes homework feel manageable and ends negotiations about "how much longer".
• A quick workout — a short bodyweight circuit or a brisk walk around the block.
• Email and admin — batch your inbox into a fixed fifteen minutes instead of letting it leak across the day.
• Daily reading or practice — fifteen minutes a day of an instrument or a language adds up to over 90 hours a year.

Ready for a Longer Block?

When fifteen minutes starts to feel easy, step up to the 20 minute or 25 minute timer. Our free Focus app includes a 15/3 preset that alternates focus and breaks for you.

Study Without the Screen

If your browser is the thing distracting you, a physical study timer keeps time on your desk while your phone stays in another room.
