Turn study time into focused sprints with Cognitive Pathways, Glow Points, streaks, and a glowing brain visual that helps make focus feel more rewarding.
The brain glow is a visual focus indicator — not a medical scan, diagnostic tool, or guarantee of academic results.
Phones, notifications, open browser tabs, academic pressure, and constant task switching can make studying feel fragmented — even when you sit down with every intention to work.
A focus timer gives study time a clear start and finish. Instead of an open-ended stretch of time that's easy to procrastinate into, a bounded session gives your brain a defined sprint to commit to. Finishing that sprint, however short, builds the habit of returning to focus.
Cortex Lantern helps make that study sprint feel more visible and rewarding — turning a countdown into a record of practice.
A normal timer counts down. Cortex Lantern turns your study session into visual attention training. You choose a Cognitive Pathway, start a focused sprint, earn Glow Points, and watch a glowing brain visual respond as you stay with the session.
The brain glow is a visual metaphor — not a readout of your brain state. It is designed to make study time feel more visible, more rewarding, and easier to return to. Each completed session earns Glow Points and extends your streak, building a record of consistent practice over time.
Cortex Lantern is not a guarantee of better grades or improved academic results. It is a focus timer and attention-training tool — designed to help you show up to your study sessions more consistently.
Cortex Lantern has five Cognitive Pathways. Here is how each one applies to common student tasks:
The right session length depends on where your focus is right now — not a fixed rule:
Starting shorter than you think you need is almost always more effective than forcing a longer session. Build gradually.
Cortex Lantern works for any study task that benefits from a focused, distraction-free sprint:
For study tasks that need sustained concentration, the Deep Work Timer guide covers session lengths and setup in more detail.
The best focus app for students is one that helps you start a session, stay with it, and build a consistent habit over time. Cortex Lantern is a focus timer and attention-training app with Cognitive Pathways for different types of study, Glow Points for completing sessions, and a glowing brain visual that makes study time feel more visible. It does not guarantee grades or academic results.
Yes. Cortex Lantern includes pathways built for common student tasks: the Learning pathway for reading, revision, and lectures; the Deep Work pathway for essays, assignments, and coding; and the Problem-Solving pathway for maths, logic, and exam prep. Sessions can be as short as 15 minutes, which makes it easy to fit around a study schedule.
Not exactly. A Pomodoro timer counts down a fixed 25-minute block. Cortex Lantern adds Cognitive Pathways for different types of study work, a glowing brain visual, Glow Points, streaks, and a focus history — making the session feel like attention training rather than just a countdown.
It depends on your current focus capacity. 10–15 minutes is a good starting point when focus feels low. 25 minutes works for a light study sprint. 45 minutes suits deeper study blocks. Sessions of 60 minutes or more are best when you already have strong focus momentum. Starting shorter and building gradually is more effective than forcing long sessions.
No. Cortex Lantern does not measure brain activity. The glowing brain visual is a visual metaphor — designed to make your study session feel visible and rewarding. It is not a medical scan, EEG, or diagnostic tool of any kind.
Yes. Cortex Lantern is free to download and use on iOS. A Pro upgrade is available for users who want additional features. Download it on the App Store.
