Tools for better timing

Track patterns, not perfection.

Restadian tools are built to show you your own schedule. They take what you already do — when you wake, when you drink coffee, when you get light — and lay it out so the pattern is visible. None of them score you, and none of them tell you what your night should have looked like.

Every Restadian tool

  • Tool 01

    Circadian Planner

    A seven-day schedule for sleep opportunity, morning light, evening wind-down, and gradual time shifts, built around the week you actually have.

  • Tool 02

    Fourteen-Day Sleep Diary

    Record sleep timing, awakenings, naps, caffeine, exercise, and morning alertness for two weeks, and see the pattern underneath the individual nights.

  • Tool 03

    Sleep Regularity Report

    See how much your bedtime and wake time move across a week, including the gap between your weekdays and your weekends.

  • Tool 04

    Jet Lag Planner

    Enter your route and dates, and get a practical schedule for adjusting before, during, and after a time-zone change.

  • Tool 05

    Caffeine Cutoff Calculator

    Estimate a reasonable last-caffeine window from your bedtime, your intake, and your own sense of how strongly it affects you.

  • Tool 06

    Shift-Work Planner

    Organise sleep opportunity, naps, light, caffeine, and transition days around a rotating or overnight schedule.

How these tools behave.

  • Nothing you enter leaves your browser unless a tool says otherwise.
  • No account, no login, no email required to use one.
  • One adjustment at a time, measured across a fortnight rather than a night.
  • Every output is an estimate, and every tool says so in its own words.
