Body Measurements

mojo tracks the following body metrics to help you understand how your body changes throughout your weight loss journey.

What Gets Tracked

Primary Measurements:

• Weight (kg / lb)
• Body Fat % (%)
• Fat Mass (kg / lb) — can be logged independently or calculated automatically from weight × body fat %
• Muscle Mass (kg / lb) — skeletal muscle weight

Specialized Measurements (Premium):

• Visceral Fat Level (1–59)
• Waist Circumference (cm / in)

Visceral Fat Levels Explained

mojo categorizes the visceral fat level (1–59) you log into three tiers:

Visceral fat level is a measurement provided by body composition scales (e.g., TANITA, Omron). Different brands may use different grading thresholds; mojo uses the tiers above as a reference.

How to Log Data

Auto-Sync (Recommended)

Use a smart scale that supports Apple Health / Health Connect. After stepping on the scale, your data syncs to mojo automatically.

What can sync automatically:

• Weight and body fat % (iOS + Android)
• Waist circumference (iOS only, via Apple Health)

Manual Entry

Go to Settings → Data Management → Body Measurements and tap the ”+” button in the top right.

The following can only be entered manually for now:

• Muscle mass (Apple Health and Health Connect don’t support skeletal muscle mass)
• Visceral fat level
• Waist circumference (Android)

Progress Charts

View trend charts in the Progress tab:

• Weight, body fat, and muscle mass trends over time
• Time range options: 1 month / 3 months / 6 months / All
• Tap a data point to see the exact value
• Automatically displays in your preferred unit (kg/lb)

Charts use injection dates as the X-axis reference, pulling measurements recorded within 3 days before or after each injection. Building a habit of weighing yourself before each injection will give you more complete chart data.
