Degrees from level. Level and center are reference lines, not goals; a small difference between sides is normal. "Left" and "right" are the person's own sides, not the screen's. "Body over feet" is an estimate of where the hips sit between the feet in the picture. It does not measure weight. In live view, the ± figure shows how much the reading wobbles over the last second.

What changed
Changes under half a degree, or under 3% for body over feet, are within the app's normal wobble. Hammah counts them as about the same.
Sit to stand Testing only
Live camera only. Sit facing the camera, about 8 feet away, so your whole body stays in view when you stand. Tap Record a stand. When Hammah says “Stand up,” stand at your own pace. Stay standing until it says “Done.”
Use a firm chair with its back against a wall. Keep a helper or a counter within reach. Stop if you feel dizzy, unsteady, short of breath or in pain.
The path the middle of the hips took from seated to standing. Straight up the middle means no side shift.

What changed
Record another stand to compare it with this one.
Hammah sees from the front, so it shows side-to-side movement and timing, not how far you lean forward. Sway once up is how much the hips move side to side in the first second after standing; smaller is steadier.

Set-up for a fair reading
Prop the phone upright and level, at about waist height. With the live camera, a green bar at the top means the phone is level.
Stand 6–8 feet away, facing the camera, whole body in frame, feet included.
Fitted clothing helps the app find the shoulders and hips.
Plain background, good light from the front.
Use a firm chair without armrests, square to the camera.
Prop the phone upright and level, at about seated chest height, 5–6 feet away. With the live camera, a green bar at the top means the phone is level.
Head, shoulders, hips and knees in frame. Feet flat on the floor.
Keep hands resting on the thighs, not in the lap, so the hips stay visible.
