Small calculators: a sleep planner, caffeine and bedtime, compare your days, your movement week, focus and screens.
Go to Health and select the Tools tab. Each card says the question it answers.
The sleep planner works back from the time you need to be up: when to start winding down and when to have the lights out. It shows the sleep you actually logged over the last two weeks beside it, and can add the wind-down to today’s schedule.
Type your last coffee or tea and your bedtime. It shows roughly how much caffeine could still be with you at bedtime, as a range, because people clear it at very different speeds.
Pick sleep, movement, water or screen time and see the mood and stress you rated on days on each side. It needs at least three days on each side, and it is a pattern in your own logs — not proof of cause.
Movement week adds up the minutes and days you logged in the last seven days. Focus and screen time sets your focused hours beside your screen time outside work.
Most tools offer a one-week experiment, pre-filled. You confirm it, and it runs on My Journey, where the result is compared with the days before.
The tools only save when you press a button, and none of it is medical advice. Each one links to the lessons behind it.
