Lumen turns a noisy, overwhelmed mind into a calm, clear plan.
Built for ADHD brains (and anyone with too much on their plate), Lumen makes capturing and organizing effortless. Get everything out of your head in seconds, then let it sort into a plan you can actually follow.
How it works
- Brain-dump: add everything on your mind in one fast list. No fields, no setup, no friction.
- Sort with AI: tap Sort and Lumen organizes your dump into Today, Upcoming, and Ideas, detecting dates and times for you.
- Plan your day: a clean Today view shows what is next, with a planner for what is coming up.
- Stay on time: a calm countdown shows how long until your next timed task, so nothing sneaks up on you.
- Ask Lumen: not sure where to start? Ask what to focus on and get a clear next step.
- Swipe to act: swipe any task to schedule it or mark it done.
Designed to feel calm
- A quiet, focused interface that does not overwhelm.
- Light and dark themes.
- Available in English, French, Spanish, German, Portuguese, Italian, and Chinese.
