A gentle focus gym for your brain
Cortex Lantern is an attention-span training app — a gentle focus gym for your brain. It helps you train sustained attention using tiny focus sessions (15–45 minutes), Cognitive Pathways, and visual feedback like Glow Points, streaks, and Cortex Levels — without guilt, pressure, or hustle culture.
Using Cortex Lantern is simple. Here's the core loop:
That's it. Repeat this loop regularly, and you'll build attention capacity over time.
Cognitive Pathways are the five focus modes in Cortex Lantern. Each pathway is designed for a different type of work:
Matching your pathway to your task helps you train the right type of attention for the work you're doing. For guidance on session lengths and setup, see the Deep Work Timer page.
Short sessions reduce friction. When you know a session has a clear endpoint, it's easier to start. A 15-minute session you actually complete is worth more than a 90-minute session you never begin.
Based on the science of attention training, repeated short sessions are more effective than occasional long ones. Start short, repeat often, and gradually extend your sessions as your attention capacity grows.
When you complete a session, you earn Glow Points. These are simple visual rewards that acknowledge your effort — not a measure of "productivity," but a record of showing up.
As you accumulate Glow Points over time, you progress through Cortex Levels. The system is designed to motivate you gently, without pressure or guilt. There's no leaderboard, no punishment for missing a day. Just encouragement to keep going.
Cortex Lantern tracks your sessions, streaks, and overall progress. Over time, you can see how consistently you've practiced and how your attention capacity has grown.
Streaks are gentle nudges, not obligations. If you miss a day, you don't lose your Glow Points or your level. You just start a new streak when you're ready.
For those who need extra flexibility, Cortex Lantern is designed to be ADHD-friendly — with low friction, forgiving streaks, and no guilt.
A Pomodoro timer mainly tracks blocks of time. Cortex Lantern is designed as an attention-training app: you choose a Cognitive Pathway, start a focus session, watch a glowing brain visual respond as you train, and build progress through Glow Points, streaks, and focus history.
The brain glow is a visual metaphor for your focus session — not a medical scan or measurement. It helps make deep work feel more visible, rewarding, and easier to return to.
Not exactly. While timed sessions are part of it, Cortex Lantern adds Cognitive Pathways for different types of work, visual brain feedback, and a Glow Points system designed for consistency over time.
Start with 15 minutes. If that feels easy, try 25. You can always adjust later. The goal is to build a habit, not push to exhaustion.
No. Cortex Lantern rewards effort, not output. If you complete a session, you've succeeded — regardless of what you "accomplished."
Cognitive Pathways are the five focus modes in Cortex Lantern: Deep Work, Learning, Creative, Problem-Solving, and Communication. Each is designed for a different type of task.
Glow Points are earned by completing focus sessions. They reward consistency, not productivity — a record of your practice over time.
