Cortex

v3.1 · Updated Apr 2026

A Pomodoro timer for med students.

The classic 25/5 Pomodoro was built for a 1980s desk job. Cortex is shaped around long-haul study: 50-minute focus blocks with breaks that grow as a session stretches, matching how attention actually decays over a marathon.
During a block the interface all but disappears — a single dimmed ring and the time remaining. Everything celebratory waits for the break screen, where it can’t pull you out of the work.

What Cortex does

The handful of things it does, done properly — nothing bolted on for a feature list.

01

Long-haul focus blocks

50/10 by default, with breaks that lengthen as the session goes on. 

02

The interface disappears

A single dimmed ring and the time left. Nothing dances, nothing notifies. 

03

Streaks, kept quiet

Stats and streaks live one screen away — present, never in your face. 

04

Loud only on breaks

The app celebrates on the break screen, then gets out of your way again.
