52–17 Focus is a free web timer for people who find 25-minute Pomodoro sessions too short. It uses a fixed 52-minute focus and 17-minute break rhythm, with daily tasks, cycle goals, and a monthly focus calendar stored locally in your browser. No sign-up required, and it works on desktop and mobile.

Hi Product Hunt! 👋 I’m Shinya, an independent creator from Japan. I built 52–17 Focus because 25-minute Pomodoro sessions often felt too short for me. Just when I was getting deeply focused, the timer would interrupt my work. So I created a simple timer based on a longer rhythm: • 52 minutes of focused work • 17 minutes of proper rest • Daily task management • Cycle goals • A monthly focus calendar • No registration required Everything is stored locally in your browser, and the app is free to use on both desktop and mobile. My goal is to create a simple tool that helps people focus deeply without making productivity feel complicated. I’d especially love your feedback on: • Is the 52/17 rhythm comfortable to use? • Is the interface easy to understand? • What feature would make you use it regularly? Thank you for checking out 52–17 Focus!

The 52/17 split actually feels right for my deep work sessions, way better than Pomodoro for me. The monthly calendar view is a nice touch, and I love that nothing leaves my browser.

the 52/17 split is honestly a really nice choice over the usual 25/5, and i love that the monthly calendar lives right in localStorage without any account nonsense. clean little tool.
