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: I don’t have an Apple Watch — can I enter exercise and sleep myself?

Yes. There is no exercise or sleep input inside the mojo app, but you can add both by hand in the iPhone’s built-in apps, and they sync to mojo through Apple Health:

Exercise: Health app → Browse → Activity → Workouts → Add Data in the top-right (on iOS 26 you can also add one straight from the Fitness app’s Workout tab)
Sleep: Health app → Browse → Sleep → Add Data in the top-right → pick an Asleep sleep type

Prefer a specific sleep stage (Deep, Core, REM) over “Asleep” or “In Bed” — “Asleep” and “In Bed” both only show as an unstaged total, and “In Bed” additionally only counts if it doesn’t overlap a sleep sample of another type.

Step-by-step instructions are in Entering Data.

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?

Micro-feedback triggers automatically when you log or update data. There is a cooldown between updates: 3 hours for mojo Friend subscribers, 24 hours for free users.

Full AI reports can be regenerated every 15 minutes from the mojo tab.

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: Why can a lower weight or body fat value appear higher on the trend line?

The progress chart uses smoothed lines to make the overall trend easier to read. When you tap the chart, the weight, body fat, muscle, and other values shown in the tooltip are your actual recorded data and are not adjusted.

Around short-term turns, such as a dip, rebound, and another drop, the smoothed line uses nearby data points to draw a gentler curve. This can sometimes make the line appear higher than the actual value at that point. This is a chart display effect, not a data error.

When reading the chart, rely on the tapped value for the exact record; use the line mainly as a guide for the long-term direction.

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

Data Management

Q: How do I back up my data?

Go to the Settings tab → Data Management → Backup & Restore to export all your data as a backup file.

The backup includes: injection records, body measurements, nutrition logs, water intake logs, side effect records, Streak settings, and more.

The backup file you export by hand uses the same format on iOS and Android, so you can restore across platforms.

mojo has a few ways to back up, depending on the platform you’re on:

Manual export: a readable JSON file you keep yourself. Exporting needs a subscription; importing a backup file to restore it is free
iCloud auto backup (iOS only): encrypted and saved automatically to your own iCloud, needs a mojo account, free
Google device backup (Android only): handled by the Android system and restored automatically when you reinstall the app, free

For how to turn each one on, and what its limits are, see Data Import & Export.

Q: How do I delete all my data?

mojo’s data ends up in several different places, and each has to be cleared separately:

Delete your account: this clears your account data on mojo’s servers. The health records on your device are not deleted. Account deletion cannot be undone
Clear the data on your device: delete records one by one on each record page, or simply remove the app
Copies in Apple Health / Health Connect: if you granted mojo permission to write there, a copy of your weight, body fat, waist, nutrition, and hydration stays in the system health app. Removing mojo does not clear it; delete it in that app
Cloud backup files: these do not disappear when you delete your account or remove the app, and the three kinds are handled separately. Files written by the in-app iCloud automatic backup sit in iCloud Drive and have to be deleted by you in the Files app; mojo’s data inside an iOS whole-device backup is not visible in the Files app, so you delete the whole device backup in the iOS iCloud backup settings or exclude mojo from it; Android system backups are managed in your Google account’s backup settings

To delete your account:

Back up first (recommended)
Go to the Settings tab → Subscription & Account
Tap Delete Account
Confirm to proceed

Q: How do I restore my data on a new device?

Install mojo on the new device
Sign in with the same account, and account-level data such as subscription status comes back
Health records do not come back with the sign-in; they have to be restored from a backup
Re-authorize Apple Health / Health Connect, then sync again

How to restore health records: if you still have the old phone, the system’s phone-switching flow (Android’s device transfer, iPhone’s Quick Start) copies mojo’s data straight to the new phone with no cloud backup involved. If the old phone is gone:

iOS: if mojo’s in-app iCloud auto backup completed at least once on the old phone, you can restore straight from the “Welcome Back!” screen after signing in on the new phone (for the conditions and the other way in, see Data Import & Export). With no cloud backup, restore the new phone from an iCloud whole-device backup — but that can only be chosen during the new phone’s initial setup (or after erasing it); a phone you’ve already finished setting up can’t do it retroactively.
Android: a system device backup has to have actually completed on the old phone (not just the switch being on), and the new phone has to pick that backup during initial setup while signed in to the same Google account — then mojo’s data comes back when the app installs. Skip the restore step during setup and a later install can only restore that device’s own backup, not the old phone’s.

On either platform you can also go to the Settings tab → Data Management → Backup & Restore and import a backup file you exported earlier by hand.

Account

mojo supports multiple sign-in methods:

Apple Sign-In (iOS) — tap “Sign in with Apple” on the login screen
Google Sign-In (Android) — tap “Sign in with Google” on the login screen
Email + OTP (iOS & Android) — under Other sign-in options, enter your email, then a 6-digit verification code (no password required)

You can link more methods under Settings → your account card at the top → Login Methods. See Sign Up & Login for details.

There’s no Apple Sign-In on Android. Under Other sign-in options on the login screen, enter your Apple ID email address and the verification code — you’ll be signed back into the same account (if you’ve changed your mojo account email before, enter that email instead). Don’t enter a different email or tap Google Sign-In (a non-matching email creates a new account).

If you chose “Hide My Email”, we recommend changing your account email to one you own under Settings → tap your account card at the top → Login Methods while you still have your iPhone, then signing in on Android with the new email. If your iPhone is already gone, contact support. See Sign Up & Login for details.

Q: Can I be signed in on multiple devices at the same time?

Yes. Sign in with the same email on multiple devices — subscription status will sync across all of them.
