Body weight check-ins
Tap the + button on the Progress page to open the daily check-in sheet. Enter your weight in kilograms or pounds, whichever unit you’ve set in preferences, and the app records it with a timestamp.1
Open the check-in sheet
Tap the + button in the Progress header. If you’ve already checked in today, the sheet pre-fills with today’s entry so you can update it.
2
Enter your weight
Use the large numeric input or the +/− steppers to set your weight. The previous check-in is shown for reference so you don’t have to remember yesterday’s number.
3
Add optional measurements
Tap Add measurements to reveal fields for body fat percentage and circumference measurements: waist, hips, and chest. These are optional on any given day.
4
Add a journal note
Tap Add a note to record anything worth remembering: training quality, sleep, appetite, or how you felt. Notes stay attached to that check-in.
5
Save
Tap Complete check-in. Your weight and any measurements appear in the Body progress charts immediately.
Editing and deleting past check-ins
The Recent check-ins list under the Body charts shows your five most recent entries, newest first, with Show all underneath when there are more. Five is the glance; everything older is a deliberate ask. Each row carries its own edit and delete controls. Tap a row to open the check-in sheet on that day with its numbers already filled in. Tap the bin icon to delete that check-in outright. Rows read from a connected scale are labelled Synced. Editing one makes it yours: from then on, health sync leaves that day alone rather than writing over your correction. The pencil in the Progress header opens a flatter version of the same thing: a day stepper reaching back a week, and weight, body fat, waist, hips, and chest as five plain fields. No disclosure to open, and no carrying yesterday’s weight forward into a day you are only passing through.Both sheets only write the fields they show. Correcting Tuesday’s weight does not disturb the arm and thigh measurements recorded that day, and does not copy today’s numbers onto it.
Body measurements (circumferences)
Each check-in can include circumference measurements in centimeters:- Waist: the most common measurement for tracking fat loss
- Hips: useful for body composition context
- Chest: tracks upper-body changes
- Arms: tracks bicep or general upper-arm size
- Thighs: tracks lower-body changes
- Calves and neck: available through the API and MCP for anyone who tracks them
Body-fat estimates
You can enter a body-fat percentage with any check-in. OneRep uses this, along with your weight, to display lean mass trends alongside total weight trends. If you have a body-fat reading from a scale, DEXA, or a trained estimate, enter it here. A check-in can also carry lean body mass, bone mass, and basal metabolic rate. These arrive on their own when a smart scale writes them to Apple Health or Health Connect and you have the matching switch on. See Health for how synced readings and typed ones share the same day without overwriting each other.Trend metrics
The Body tab in Progress shows charts for the metrics you’ve been logging. You can switch between trend views for:- Body fat %: your logged body-fat percentage over time
- Waist: circumference trend in centimeters
- Chest: circumference trend in centimeters
- Arms: circumference trend in centimeters
- Thighs: circumference trend in centimeters
