Your day, built by you.
Create one-time, daily, or weekday tasks yourself. Add notes, choose the start time, and set the deadline.
Build a roadmap with real time windows.
Finish what matters on time and keep the evidence.
Every task has a start time and a deadline.
Winter Arc gives every routine and goal a place in today's schedule, then records whether you kept the promise while it still counted.
Create one-time, daily, or weekday tasks yourself. Add notes, choose the start time, and set the deadline.
A task stays locked until its start time. Finish inside the window for an on-time result, or complete it late without rewriting the record.
Track a daily routine or a specific goal such as LeetCode Daily directly from the same roadmap—on desktop, mobile, or keyboard.
See your overall daily contribution and a separate binary heatmap for every tracked routine. Only an on-time finish fills the block.
Add each task manually, choose when it becomes available, and set the deadline that makes it count.
Track a daily routine or specific goal from the same task. There is no second checklist to maintain.
On-time work fills the overall contribution grid and that task's own heatmap. Late work stays honestly late.
