After every completed session, Particle now asks a simple question: how did that feel?
Five options. One tap. Energizing, Light, Neutral, Heavy, or Draining. A gentle overlay appears in the center of your screen, stays for twelve seconds, and leaves without a trace if you choose not to answer. No pressure. No guilt if you skip it. A thin line at the bottom shows how long you have — then it's gone.
This isn't a mood tracker. It's the first step toward something much larger.
We believe that to do the best work of your life, you need to understand how your work affects your body. Not just what you accomplish — but what it costs. Which tasks energize you. Which ones drain you. Which patterns lead to your best days, and which ones lead to burnout.
Your wearable tracks your heart rate, your sleep, your recovery. But it can't see what you were doing when your stress spiked at 2 PM. That's the missing connection — work and body, together in one place. We call it Vitals, and this simple question is where it begins.
Every rating you give teaches the system. Over time, patterns emerge: creative work feels light, admin feels heavy, mornings energize you, afternoons drain you. When we introduce Vitals later this year, these subjective ratings will combine with objective biometric data to reveal something no tool has ever shown you — the true relationship between how you work and how you feel.
For now, it's just a question. But behind that question is a vision: work should be a positive force in your life. Not something that breaks you down, but something that builds you up. And the first step to getting there is noticing how it feels — one session at a time.
