Every session already captures duration, project, and time of day. What it didn't capture was the thing that matters most — how the work felt.
Now it does. After each session, Particle asks one question. Five options, from Energizing to Draining. One tap. No friction.
Those answers become Vitals — four insights that reveal what your calendar never could:
Project Energy. Which projects give you energy. Which ones cost it. Not which take the most time — which take the most out of you.
Best Hours. When during the day your work feels lightest. Your peak isn't when you're most productive. It's when you're most alive.
Sweet Spot. The session length where energy peaks before it starts to drop. Everyone has a different inflection point. Vitals finds yours.
Feeling Trend. Whether your work energy is improving, holding steady, or declining — this week, last month, and over time.
Each insight appears on a visual spectrum. No numbers to decode. A marker on a gradient from Energizing to Draining. You understand it in a glance.
Insights unlock progressively as you rate more sessions. Every rating makes the picture sharper. This is the beginning of something much larger — connecting how work feels to what it costs your body.
