I often felt like I was sitting at my desk for hours, but at the end of the day I didn’t feel productive. I wanted to know how much of each hour was actually spent working, not just sitting there. By tracking only my focused working minutes, I started to see my real limits. It became clear when my focus faded, how long I could truly sustain attention, and how to plan my working hours around...

ChronA quiet instrument for measuring focus.
A minimalist work timer designed for focus, not distraction.
Track your working time with a single tap, but with one rule: be honest. Start the timer when you work. Stop it the moment you’re distracted. No rounding up, no pretending.
Over time, the data reveals when you do your best work, when your focus fades, and when it’s time to step away from the desk.
No ads. No gamification. No noise.
