Lernis is a free focus timer built on the Pomodoro technique: blocks of deep work, gentle breaks, zero distractions. No sign-up, works offline.
A focus timer isn't about counting minutes: it's about drawing a boundary. Inside it there's one thing to do, and outside it there's everything else — which can wait. Lernis turns 25 minutes into protected space, then gently reminds you to breathe. Repeat, and focus stops being a fight.
No endless lists. Pick one intention, start the timer, and for the whole session only that exists. It's the single-tasking your brain has been craving.
No notifications, no banner covering the timer. Just silence — or the ambient sound you choose: rain, forest, café. The right noise to disappear into the work.
The research is clear: short sprints beat marathons. Lernis alternates focus and breaks with gentle reminders, so you end the day focused, not drained.
The classic 25 minutes are just the start. Stretch your blocks up to 90 minutes when you hit flow, shorten breaks when you're on a roll. The timer adapts to your work, not the other way around.
