Focus & Sleep Planner

Caffeine remaining after hours, and the time until it drops below a threshold, from a half-life you can set (default 5 hours).

Day-by-day bedtime and wake-time shift toward a new time zone, with dates and 12-hour clock times. Planning only.

Nap lengths (10, 20, 30, 60, 90 minutes or your own) with the wake-up clock time for each, and a bedtime gap check.

Pomodoro schedule for a task total in minutes: work blocks, short breaks, a long break every N blocks, with 12-hour clock times.

Split a time window into equal blocks with breaks between them, with 12-hour clock times and the minutes left over.
