A focus app for deep work
The work of a lifetimeconsists of many particles.
A focus timer that's keyboard-first and works with no account. Generative soundscapes when silence isn't enough.
Free. No account needed to start.
Team work is tracked, shared, kept in sync — the board, the tickets, the standup.
Your own work has no such room. Just you, the task, and the hour you give it.
Particle is your desk,not the dashboard.
The Particle Loop
Great work isn't linear.
It's a loop.
Six stages of focused creation that turn everyday work into your life's work.
01
Capture
Collect every spark before it fades.
02
Plan
Shape your day around what matters.
03
Execute
Enter deep work. One particle at a time.
04
Complete
Mark the moment. Every particle counts.
05
Reflect
See your rhythm. Understand your patterns.
06
Align
Ask whether this still serves what matters.
Focus
Beauty in simplicity.
Every detail crafted with care. A timer that respects your attention — nothing extra, nothing missing. Keyboard-first: every action one keystroke away. Overflow mode when the flow demands it.
Your Sonic Field
Sound designed for your focus.
Generative soundscapes, curated radio stations, and a loop engine to build your own. Three ways to find your sonic space.
Atmospheres
Your workspace looks how you feel.
Transform the entire app with visual atmospheres — not just themes, but moods. Each one changes colors, textures, and glow to match your state of mind.
Your Companion
One honest observation a day.
Drawn from what you actually logged — not generated mood-talk. It notices patterns ("your deepest runs are before noon") and stays quiet the rest of the time. It won't pretend to understand how you feel.
Rhythm & Reflection
The stage most tools skip.
Most tools stop at the timer. Particle shows you the shape of your work — daily, weekly, yearly. When you focus best. Where your energy goes. Whether your work still aligns with your vision. Reflection, not just tracking.
Your Sonic Field
Sound designed for the way
you actually work.
Most focus sound is a three-hour loop or a noise generator. We tried for something better — generative audio, with one hard rule: nothing that could ever startle you. If silence is working for you, use silence.
Radio
Curated Stations
Handpicked for deep work.
Continuous streams of ambient music, lo-fi, and atmospheric sound — curated for focus, not distraction. Press play and disappear into your work.
Soundscapes
Generative Presets
Generative audio.
Every preset obeys hard limits — nothing above ~1.2 kHz on melodic content, attacks never sharper than 10 ms — so a sound can soothe but never startle. The reasoning, and the papers, are public.
Loops
Build Your Own
Your sonic environment. Your rules.
Layer individual sound elements to create your personal focus atmosphere.
What We Believe
Opinionated by design.
Tools are never neutral.
Less is more, always.
Craft over speed.
Pride over guilt.
Machines execute. Humans judge.
Sound is not decoration.
And what we'll never build: streaks to break, red badges, fake AI empathy, or anything that sells your attention.
Your career. Your income. Your sense that the day meant something. It all traces back to how you spend your working day.
People plan their workouts. Budget their money. Track their sleep. But the thing that shapes all of it runs on autopilot.
It doesn't have to.
Our Promise
We build so you can build.
Our job is to disappear. The less you notice Particle, the better we did our work.
I'm Waldemar. I built Particle alone, bootstrapped — because every focus app I tried left me feeling worse, not better.
