Editor's Review
Most focus timers are overloaded with clutter and noise that defeat the whole purpose. Sumkan takes the opposite approach. I started a 25-minute session with a single tap, and the breathing background animation is a simple but effective touch. The task-linking feature is genuinely useful—I planned my morning writing block, and the session record showed exactly what I worked on.

Sumkan is a calm Pomodoro focus timer that helps you build a steady rhythm of deep work and mindful breaks — on your phone, tablet, and Android Watch.
Start light, focus deep. Tap once and a quiet 25-minute focus session begins, followed naturally by a short break. No noisy dashboards, no pressure — just a timer you can trust.
