If you experience any issues, contact your coach or visit the SELFLOOPS Support Center for additional troubleshooting guides.

If you use a Garmin chest strap with our Group Fitness app or with your coach’s class setup, you may be asked for your sensor’s ANT+ ID — the unique number that identifies your heart rate monitor so the system always picks up your signal and not your neighbor’s.

There’s just one catch: Garmin doesn’t print this number anywhere on the strap. Don’t worry — finding it takes less than a minute. Here are the easiest ways, starting with the simplest.

Method 1: Read It from Your Phone (Bluetooth Name)

If you have a modern dual-protocol Garmin strap — HRM-Dual, HRM-Pro, HRM-Pro Plus, HRM-Fit, HRM 200, or HRM 600 — the ANT+ ID is hidden in plain sight: it’s part of the Bluetooth name your strap broadcasts.

1. Put the strap on. Garmin monitors only transmit when they detect skin contact. (Tip: touching both snap contacts with damp fingers also wakes it up.)
2. On your phone, open Settings → Bluetooth. Your phone automatically scans for nearby sensors — no extra app needed. On iPhone, look under “Other Devices”; on Android, tap “Pair new device” if the list doesn’t appear right away.
3. Look for a device named something like HRM-Dual:1234567 or HRM-Pro:9876543. There’s no need to tap or pair it — just read the name.
4. The number after the colon is your ANT+ ID. Write it down — it never changes for the life of the strap.

If you’re in a busy gym and see several straps, yours will be the one with the strongest signal, since it’s on your chest. Step a few meters away from other people to be sure.

Method 2: Check Your Garmin Watch or Edge Computer

Already paired your strap with a Garmin watch or bike computer? The ID is stored right there:

1. On your device, go to Settings → Sensors & Accessories.
2. Select your heart rate monitor from the list.
3. Open the sensor details or “About” page — the number shown as the Sensor ID is your ANT+ ID.

Menu names vary slightly between models, but the path is always through the sensors menu.

Method 3: Ask at the Front Desk (Older Straps)

Have an older ANT+-only strap, like the classic HRM3 or an early HRM-Run? These don’t broadcast Bluetooth, so the phone trick won’t work. In that case, your gym or coach can discover your sensor directly through the Group Fitness app.

To make this quick and unambiguous, wear the strap and stand close to the receiver while others keep their distance — your sensor will show up, and the staff can read the ID and link it to your profile on the spot.

Still stuck? Contact our support team and we’ll help you get set up.

The Spark Apple Watch app is included with the SELFLOOPS Spark app for iPhone. To use it with the Group Fitness application, simply select the Group Fitness activity within the Spark app.

Troubleshooting

Timer Not Starting on the Spark Apple Watch App

If the timer does not start, this usually indicates a permissions issue preventing the app from accessing the Apple Watch heart rate sensor. To resolve this:

1. Check permissions in the Spark iPhone app:

• Open the SELFLOOPS Spark app on your iPhone.

• Go to Settings > Health.

• Ensure all permissions are enabled.

2. Alternatively, enable permissions via the Health app:

• Open the Health app on your iPhone.

• Tap your profile icon (top right corner).

• Select Apps & Services.

• Choose Spark and enable all permissions.

Apple Watch Internet Connection Requirement

For Group Fitness sessions, the Spark Apple Watch app must have an active internet connection.

• If the app is broadcasting heart rate data correctly, you will see a green dot next to the time on your watch.

• If you do not see yourself in the Group Fitness session, check the following:

• Ensure your coach has added you to the system.

• Verify that the coach has synchronized the participant list in the Group Fitness app.

Our celestial-themed level system is designed to keep you motivated and engaged in your fitness journey. Here’s how it works:

• Levels and Progression: Starting from Meteorite, you advance through 28 levels like Comet, Galaxy, and Singularity. Reach higher levels by earning monthly points.
• Monthly Target: Aim for 300 points monthly reflecting WHO recommendations (150 minutes of moderate or 75 minutes of vigorous exercise per week). Points are the SELFLOOPS Training Load score.
• Missed Workouts: If you’re unable to workout due to illness or other reasons, contact our support team for assistance.
• Level Drop: Not meeting the monthly target can lead to a downgrade to a lower level. On your first failure to achieve the monthly target, you will be reset to the beginning of your current level. If you fail for a second consecutive time, you will be demoted by one level. Additionally, if you were recently promoted to a new level and fail to meet the monthly target in the following month, you will be reverted to your previous level. Once you reach level 7 you will not be downgraded below that level.

Playing a video during a group fitness session is possible. The video runs alongside the live data, but only one screen is visible at a time. You can choose to display either the live data or the video. The video starts playing when you begin the session, and during the session, you can easily switch between the screens.

To utilize this feature, first, activate the Media Content option in the app’s Settings. In the Media Content section of the group fitness app, select the desired video to play. On the main screen of the group fitness app, you can toggle between screens using the button located at the top of the screen.

Make sure to add the videos to the website. To do this, select the video library option from the training plans menu on the website. The player supports videos in the HLS video format. If you use services like Vimeo, you can export the video URL in HLS format and add it to the video library. When adding the video, select the generic type in the website.

The Apple Watch can be used to join a Group Fitness session as a heart rate monitors.

These are the steps to add the Apple Watch to your Group Fitness sessions

1) Your clients need to install the Selfloops Spark app from the App store and grant the Health options. The Selfloops Spark iPhone app includes the Apple Watch app

2) Assign an Apple Watch sensor to your client in the Equipments section in the website

3) Synchronize your clients on your device (iPad, Apple TV, Android)

4) Press START on the app

5)Your clients can start the Group Fitness workout on their Apple Watch

The new Polar heart rate monitors support the ANT+ standard in addition to Bluetooth.

In particular, the new Polar H10, the Polar OH1 and Polar Verity sense support by default ANT+. If you have an old Polar H10 and OH1, you can update their firmware using the Polar Beat application. Please refer to Polar website and support for further information about this.

To use Polar ANT+/Bluetooth heart rate monitors with the SELFLOOPS Group Fitness applications you need to enable either Bluetooth or ANT+. If you do not do it, you will see two device numbers on the screen (one for Bluetooth, one for ANT+).

To enable Bluetooth or ANT+, use the Polar Beat app and pair the heart rate monitor in the Settings of the Polar Beat app.

Enable “Visibility” if you want to use Bluetooth.

Enable ANT+ to enable ANT+ broadcasting.

The same steps apply to the H10. The H10 has some additional options.

For Bluetooth, enable only the “Visibility” option.

To use ANT+, just enable the ANT+ option.
