ByWhen: Deadline Planner

A deadline is not just a date. It is work that needs enough time before the due date arrives.

ByWhen helps you turn important tasks into practical reminder plans. Instead of relying on one alert, ByWhen looks at what needs to be done, when it is due, how long it may take, what kind of attention it needs, and when your day has realistic space for it.

Add a task, set the due date, estimate the effort, choose the task type, and ByWhen helps you stay aware of the work before it turns into last-minute pressure.

ByWhen is useful for:

- Work projects with real due dates
- Assignments, exams, and study sessions
- Calls, forms, paperwork, and admin tasks
- Errands that need time away from home or work
- Personal chores that are easy to postpone
- Daily, weekly, monthly, yearly, and selected-day routines

DEADLINE PLANS

ByWhen helps you think beyond a basic due date. It considers time remaining, estimated effort, task priority, task type, and open windows in your day.

A short call can fit differently than a focused work session. An errand that requires leaving home can be treated differently from a quick task you can do during a break.

REMINDERS WITH CONTEXT

ByWhen keeps the deadline visible as time passes. It highlights whether a task is on track, needs attention, is at risk, critical, or past due.

If you do not act on a reminder right away, the task remains part of your plan so you can return to it later.

OPEN-TIME PLANNING

ByWhen can use calendar busy blocks to avoid suggesting times that are already occupied. You can choose what to include, ignore imported blocks, and keep control of your schedule.

ROUTINE SETTINGS

Set your wake time, sleep time, work hours, and workdays so reminder timing fits your real life. ByWhen can avoid unhelpful times and protect parts of the day when reminders would not make sense.

TASK TYPES

Different tasks need different kinds of time. ByWhen supports focused work, admin, calls, study, errands, quick tasks, and away-from-home tasks. This helps ByWhen suggest more realistic moments instead of treating every reminder the same way.

REPEATING TASKS

Create repeating tasks for daily, weekly, monthly, yearly, or selected days of the week. When you complete a repeating task, ByWhen moves the next cycle forward so you are not reminded again for the period you already finished.

QUICK ACTIONS

Act from a reminder when possible. Start work, be reminded later, log time, or mark the task done so your plan can stay up to date.
