Sleep, weight and steps in one place, with Apple Health

You can track sleep, weight and steps together by recording each one in the same place and reading them side by side over weeks. Weigh yourself at the same time of day, let your iPhone count your steps, and note your sleep in one sentence or let Apple Health supply it. Putting the three in one view shows patterns that three separate apps hide.

The short version

Sleep, weight and steps are easier to understand next to each other than in three different apps.
Keep the routine small: one weigh-in at a consistent time, steps counted by the phone, and sleep logged in a single sentence or imported.
Read trends across weeks. One day is mostly noise.
Planwell can read steps, walking and running distance and sleep from Apple Health. This is optional and read only, and it never writes back.
This post covers how to record and review, not what your numbers should be. For targets or health concerns, ask your doctor.

Why track sleep, weight and steps together?

Each number on its own is a single dot. Next to the others it becomes context. A week of short nights beside a week of fewer steps tells you something that neither chart says alone, and a weight that wobbles after a poor week of sleep is easier to shrug off when you can see the sleep.

There is also a practical reason. Three apps means three places to open and three sets of charts to compare in your head. One place means you look more often, and a log you look at is the one that keeps going. An app that holds all three, such as Planwell on the App Store.

What is a low-effort routine?

The best routine is the one you can keep up when you are tired. Aim for the smallest version of each.

Weight: same time, same conditions. Weigh at the same time of day, for example first thing in the morning after using the bathroom, and in the same state of dress. A fixed time removes most of the daily noise. Several mornings a week still gives you a usable line. Record the number straight away.

Steps: let the phone do it. Your iPhone already counts steps and walking and running distance in Apple Health. The only job is to carry your phone. There is nothing to type.

Sleep: one sentence, or none. Record how many hours you slept and how the night felt. A sentence such as "slept 7 hours, woke at 6:30, felt okay" is enough. If you wear something that records sleep to Apple Health, you can pull the nights in instead of typing them.

A few seconds each morning is the whole routine.

How do I read trends instead of single days?

A single weigh-in can move because of what you ate or drank. A single night of sleep can be an outlier. Reacting to one day usually means reacting to noise.

Instead, look at a stretch of weeks:

Use a window, not a day. Compare the last 7 days with the last 30. Look at the average, not the best or worst entry.
Look at direction. Is the line broadly flat, rising or falling across several weeks?
Compare the three. When one measure changes, glance at the other two.

None of this tells you what a good number is. That depends on you, so any targets or concerns about your sleep, weight or activity belong with your doctor.

How does this work in Planwell?

Planwell is an iPhone app with 15 trackers, and three of them cover this routine: Weight, Sleep and the Activity screen for steps and distance. You switch on the ones you want. Here is what each screen shows.

Weight. The top of the screen reads "Your current weight is" followed by your latest entry in kg or lbs, with a line such as "Down 0.3 kg this week" or "Holding steady this week". Tap "Set a goal" to enter a target weight. After that you see Target and Left figures, and a dashed goal line appears on the chart. The Progress chart plots your last 14 days, and "See all" opens a history with 1M, 3M, 6M, 1Y and All ranges. Below it, Entries lists each weigh-in with the change from the one before. Tap + to log a weight.

Sleep. The top shows last night's hours and how the night felt: Great, Good, Okay, Poor or Terrible. If you recorded bedtime and wake time, those appear too, along with a ring comparing last night with a target. Switch between 7 nights and 30 nights to see the Hours chart, and tap or drag the chart to read a single night. A row of figures gives Avg hours, Longest, Nights and Under 6h. To record a night, type a sentence into the bar at the bottom, such as "Slept 7h, woke up at 6:30", or tap + to enter hours, how it felt and optional times. If you would rather speak, see voice logging.

Steps and distance. The Activity screen shows today's steps with the distance walked, a goal ring, and Steps and Distance charts for 7 or 30 days. You can tap or drag either chart to read one day.

The Home summary row. Home shows two figures between hairlines. By default weight sits on one side and today's steps on the other, with the distance walked underneath. Long press either side to choose what it shows.

The assistant can also log for you. It only runs when you start it and can be wrong, so check anything that matters.

What does Planwell do with Apple Health?

Apple Health is optional, and everything in Planwell works if you decline.

What it reads: steps, walking and running distance, and sleep.
Read only: Planwell never writes anything to Apple Health.
What it is used for: steps and distance appear on the Activity screen and on Home. Sleep fills in nights in your Sleep log so you do not retype them. Health reports how long you slept but not how it felt, so Planwell estimates a quality from the duration, and you can edit any night.
You stay in control: iOS asks which of the three you want to share. To check or change that later, open Settings, then Privacy & Security, then Health, then Planwell.

If you want a place for all three, download Planwell for iPhone. If you are also building other routines, the post on habit streaks that stick pairs well with a morning weigh-in.

Frequently asked questions

Can I track sleep and weight together on iPhone?

Yes. Planwell has Weight and Sleep trackers side by side, plus steps and distance from Apple Health, and its Home screen can show weight and steps together.

Does Planwell write data to Apple Health?

No. Planwell only reads steps, walking and running distance, and sleep from Apple Health, and it never writes anything back. The connection is optional, and the app works without it.

What is the best time of day to weigh myself?

Choose a time you can repeat, such as first thing in the morning, and use it every time. The consistency matters more than the exact hour, because body weight moves during the day.

How often should I look at my sleep and weight trends?

Once a week is a sensible rhythm. Compare the last 7 days with the last 30 and look at direction over several weeks rather than any single day.
