Health Data Sync

Q: What data does mojo track?

Data Type	iOS (Apple Health)	Android (Health Connect)
Weight / Body fat	✅	✅
Steps / Active calories	✅	✅
Workouts	✅	✅
Nutrition (calories / protein / carbs / fat)	✅	✅
Sleep	✅	✅
Water intake	✅	✅
Menstrual cycle	✅	✅

Injection records, side effects, and body measurements (muscle mass, waist circumference, etc.) are entered manually and do not rely on a health platform.

Q: Is Apple Health / Health Connect required?

No, but it’s highly recommended. mojo is designed for effortless logging: automatic sync of nutrition, exercise, sleep, and hydration eliminates manual data entry. It aggregates data from multiple apps and devices (MyFitnessPal, Apple Watch, Garmin, etc.).

Injection records, side effects, and body measurements support manual entry. Nutrition can also be entered manually or imported via deep link.

Q: How do I authorize Apple Health? (iOS)

Open the mojo app
Go to the Settings tab → Apple Health Sync
Tap Authorize
Select the data types to share (enabling all is recommended)
Tap Allow

To re-authorize (if you accidentally denied access):

Open the Health app (iOS system app)
Tap your profile picture in the top-right corner
Find mojo and tap it
Enable read access for all data types

Calorie tracking:

MyFitnessPal (free) — largest food database
Calory (paid) — clean interface with AI food recognition

Exercise & sleep:

Apple Watch — automatic exercise and sleep tracking
Garmin — professional sports watch (syncs via Apple Health / Health Connect)
Oura Ring — focused on sleep tracking

Body composition:

Omron HBF-702T — body fat scale with Bluetooth sync
Inbody H30 — professional body composition analysis with Wi-Fi sync

Q: Why can’t I see muscle mass data?

Apple Health and Health Connect do not support “skeletal muscle mass” as a data type, so mojo cannot fetch it automatically. You need to enter muscle mass data manually in the app.

Q: Will my Garmin watch data sync?

Garmin watch exercise and health data syncs first to Apple Health (iOS) or Health Connect (Android), and mojo then reads from those platforms.

Note: Some Garmin models may not write “Active Calories” to Health Connect. mojo handles this by falling back to “Total Calories Burned” for the calculation.

Injection Tracking

Q: How do I log an injection?

Open the Today tab
Find the injection progress block above the chart
Tap the block
Fill in the date, medication name, and dose
Tap Save

Q: Can I edit or delete an injection record?

Yes. Go to the Settings tab → Data Management → Injection Records, then tap the record you want to edit or delete.

Note: Deleting an injection record will affect the progress charts.

Body Measurements

Q: How do I log weight, body fat, and muscle mass?

Auto-sync (recommended):

Use a scale that supports Apple Health / Health Connect
Step on the scale and the data syncs to mojo automatically

Manual entry:

Go to the Settings tab → Data Management → Body Measurements
Tap the + button in the top-right corner
Enter the measurement values
Tap Save

Q: Why isn’t measurement data showing on the progress chart?

Possible reasons:

No injection records: The chart uses injection dates as its reference points
Measurement date outside the window: Measurements must be within 3 days before or after an injection
Measurement value is 0: Check that the data was entered correctly

Solutions:

Add at least 1 injection record
Make sure measurements fall within 3 days of an injection
Verify the measurement values are correct

AI Analysis

Q: What is Micro-feedback?

Brief feedback:

Displayed at the top of the Today tab
Auto-generated when data changes
Real-time encouragement and reminders

Example:

You hit your step goal today — great work! Don’t forget to get enough protein.

Q: What is the full AI report?

Comprehensive analysis (multi-paragraph):

Displayed on the mojo tab
Covers weight loss progress, nutrition, exercise, and sleep analysis
Personalized recommendations and risk alerts

Q: How often does the AI analysis update?

Triggers:

Data changes (adding/editing nutrition, exercise, sleep, or measurements)
30-second cooldown period
At least 5 minutes since the last analysis

Q: Can I fully trust the AI recommendations?

No:

AI recommendations are for reference only
They cannot replace professional medical advice
Consult a doctor or dietitian for any health concerns
Medication dose adjustments must be made under doctor’s guidance

Progress Charts

Q: What does the X-axis represent?

The X-axis is based on your injection record dates. Each injection date shows one data point, with the value coming from measurements taken within 3 days before or after that injection.

Q: Why is there no data point for a particular injection date?

There are no measurements within 3 days before or after that injection. We recommend building a habit of measuring before each injection, or using a scale that syncs automatically.

Q: How do I change the chart time range?

Go to the Progress tab
Tap the time selector above the chart
Choose: 1 month / 3 months / 6 months / All
