How it works

Your time. Planned, tracked, and understood.

Your calendar plans. Your tracker records. Nothing connects the two. Dayopt brings it all into one timeline.

Design your day

Timebox your hours with drag & drop. Decide how you spend your time before the day decides for you.

See what actually happened

Plan and reality, side by side. Instantly see where your time went — and where it drifted.

Get better at planning

Dayopt turns the gap between plan and reality into simple insights. Your estimates get sharper week over week.
