How do I sync data on my Frontier X to the cloud?

To view ECG data and receive insights of a workout recorded on your Frontier X, you need to sync the data on your Frontier X to the cloud.* To do so:

  1. Open the Fourth Frontier app on your phone.
  2. Go to the Menu sidebar and select Sync Data. The app will now prompt you to connect to an access point starting with “4FAP”. Select OK to connect to this access point.
  3. After you click “OK”, the file will be fetched over WiFi to your app and stored in your phone’s file system. The file will also be uploaded automatically to the server, and you will receive an email with your detailed report in three to four minutes.
  4. If the file did not get uploaded due to network connectivity issues, you can select “Re-upload Data” in the settings page (after your network issues have been resolved), and click on the upload icon next to the file name that you would like to upload. The file names are stored in the format YYMMDDHHMMSS_email.bin, where the date and time correspond to the time that you initiated Sync Data.

With the release of iOS 14, Apple devices require the user's permission to connect to any local network. If you own a device that's running on iOS 14, please follow the steps below to sync your Frontier X data to the cloud:

  1. Go to Settings-> Privacy -> Local Network, and then turn the switch on for Frontier X.
  2. Open the Fourth Frontier app on your phone. Go to the Menu sidebar and select Sync Data.
  3. The app will now prompt you to connect to an access point starting with “4FAP”. Select OK to connect to this access point.
  4. After you click “OK”, the file will be fetched over WiFi to your app and stored in your phone’s file system. The file will also be uploaded automatically to the server, and you will receive an email with your detailed report in three to four minutes.
  5. If the file did not get uploaded due to network connectivity issues, you can select “Re-upload Data” in the settings page (after your network issues have been resolved), and click on the upload icon next to the file name that you would like to upload. The file names are stored in the format YYMMDDHHMMSS_email.bin, where the date and time correspond to the time that you initiated Sync Data.
