Lumen Thoughts
One task at a time, calmly
$1.99 · Designed for iPad. Not verified for macOS.
Made for brains with 47 tabs open. Capture everything, spotlight one thing, and actually finish it. No accounts, no tracking, no subscription, just $2.99 once.
Most to-do apps are built for people who love making lists. Lumen is built for people whose lists grow faster than they shrink.
Lumen is a calm, deliberately small task app designed around how ADHD brains actually work: easy to start, satisfying to finish, and impossible to clutter.
ONE THING AT A TIME
The Spotlight is Lumen's heart. Pick any task and it moves into a single glowing card, your one job right now. Everything else waits quietly below. No wall of tasks staring back at you.
CAPTURE AT THE SPEED OF THOUGHT
One box, one button. No due dates, no priorities, no categories, no decisions. If it's in your head, get it out, sorting can happen later, or never.
TODAY AND SOMEDAY
Two lists, that's it. What's for today, and what's for someday. Move tasks between them with one tap, so your today list stays short enough to actually look at.
FINISHING FEELS LIKE SOMETHING
Check a task off and it pops, glows, and glides away. Your "done today" counter quietly keeps score, real proof of progress on the days your brain says you did nothing.
YOUR WINS DON'T DISAPPEAR
Completed tasks collect in a tidy pile you can open whenever you need the boost. The permanent Archive keeps everything you've ever finished, with timestamps, and can export your full history to Excel. Show your therapist. Show your boss. Show yourself.
FORGIVING BY DESIGN
Made a mistake? Nothing in Lumen punishes you. Un-complete a task with a clear two-tap pattern, edit any task in place, restore from the archive. No confirmations screaming at you, no accidental losses.
PRIVATE. ACTUALLY PRIVATE.
Everything you write stays on your device. No account. No cloud. No analytics. No tracking of any kind. We couldn't read your tasks if we wanted to, and we don't want to.
BUY ONCE, OWN IT
$2.99, one time. No subscription, no premium tier, no "unlock more features." The whole app is the whole app.
Lumen was made with love for overly focused minds, the people who can hyperfocus for six hours but can't start a two-minute task. You don't need a more powerful productivity system. You need a calmer one.
