52–17 Focus - A free 52/17 timer for deeper focus and better breaks

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.
