Three cards. Five signals. Zero clutter. Carbon is the task manager that gets out of your way — free on every platform.
The System
No folders. No labels. No infinite lists. Just three cards that force you to prioritize what actually matters.
What matters most right now. Commit to your day with intention, not a sprawling backlog.
Important tasks on the horizon. They'll feed into your day when the time is right.
Ideas, dreams, and long-term goals. A low-pressure space to capture everything else.
Signals
Five distinct signals give you nuance without noise. Swipe to cycle through them — your tasks tell the full story at a glance.
Smart Input
Carbon understands you. Type dates, times, tags, and delegates in plain language — metadata is extracted as you go.
Or tap the mic and speak. Voice capture works the same way.
Gestures
Swipe, shake, and tap. Every interaction is designed to feel natural and immediate.
Cycle through signals
Erase a task
Reverse your last action
Focus Mode
A built-in Pomodoro timer helps you stay focused. Work in timed intervals, take breaks, and track your productivity — all without leaving Carbon.
Set your ideal work and break durations
See your focus stats and streaks over time
Get notified when it's time to take a break
Insights
Insights shows you how you work — not to gamify your productivity, but to help you notice what's actually happening. Quiet patterns, gentle nudges.
Created, completed, let go, carrying — your week at a glance
12 weeks of history, visible in a single quiet grid
