Plan days you can actually keep.
Your plan and what actually happened, in one timeline. See where they drift — and get better at planning. The lightest timeboxing tool for knowledge workers.
No credit card required
You have a plan. You have a record. They just never meet.
Work is scattered and that's okay
Your tasks live in GitHub or Linear, your plans in your calendar, and your conversations in Slack. That's okay. But there is nowhere you decide how to use your time.
Plan and record are in different places
Your calendar shows future commitments, your tracker shows what happened. If they never meet, the drift is lost.
Reviewing is too much to keep up with
You know reflection matters, but if it requires a special ritual, you tend not to keep it up.
Dayopt is not a place to manage tasks. It is a place to operate how you use your time.
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.
Your data, open by design
Your plans and records stay yours. Dayopt won't lock them in a closed box.
Connect your time data without changing your workflow.
