If the Amissa app is not syncing data or loading as expected, these steps can help resolve the most common connectivity issues.
Steps
1. Check your internet connection
Make sure your iPhone is connected to Wi-Fi or has a strong cellular signal.
Test by opening another app or website to confirm connectivity.
2. Restart the app
Close Amissa completely.
Reopen the app and check if data begins to sync.
3. Restart your device
Power off your iPhone, wait a few seconds, and turn it back on.
Open Amissa again.
4. Verify Health app permissions (if wearable data is missing)
Open the Health app on your iPhone.
Go to Profile > Apps > Amissa.
Confirm the data types you expect (sleep, activity, heart rate, etc.) are enabled.
5. Confirm patient status
If you are unable to view a patient’s data, check that the patient has accepted their Amissa invitation and is actively logging data.
6. Update the app
Open the App Store and confirm that you’re using the latest version of Amissa.
Update if needed.
7. Reinstall if needed
If issues continue, delete the app and reinstall it from the App Store.
Log back in using your provider credentials.
Helpful Details
Connectivity issues are often related to internet access, outdated app versions, or permissions in Apple Health.
If wearable data isn’t syncing, first confirm the data appears in the iPhone Health app—Amissa can only import what Health already has.
Patients must consent to data sharing when joining Amissa. Researchers do not receive data without consent. Amissa does not sell data to advertisers or marketers.
Next Steps
If you’ve tried all of the above and the issue persists, contact the Amissa support team through the Help Center with details about your device, app version, and the issue you’re experiencing.
