• EI Potential effortlessly tracks heart rate, GPS, and gaits daily using your phone and heart rate sensor.
• Fundamental training principles reflecting optimal training are employed to tailor training for individual horses.
• Monitoring multiple horses is possible.
• Assistant riders can be added.
• Provides personalized insights and actionable knowledge to reduce injuries and improve wellbeing

Yes, you can. Depending on the type of subscription you can activate as many horses as you like.

Yes, you can. When you have an activated horse, you can add as many assistant riders for that horse. Be aware, these assistant riders then are able to see all activities of your horse(s).

The heart rate of your horse is measured by using a Bluetooth heart rate sensor. All Bluetooth heart rate sensors with Bluetooth 4.0 and ANT+ are supported by EI Potential.

Speed and distance are measured using the GPS on your phone. When you are training indoors, GPS is mostly not available therefore speed and distance can be lacking or incorrect.

Yes, you can. In the sensor settings menu, you can change the sensor settings of your Polar sensor to 'dual connection'  which enables this sensor to simultaneously connect to EI Potential and your Polar watch. Therefore, during training you can see the heart rate of your horse also on your watch when necessary.

Yes, the EI Potential app on your phone connects to the Bluetooth heart rate sensor on your horse and therefore you can make a registration.

Important: Wear your phone in a pocket on the left side of your body. This as the heart rate sensor is also located on the left side of the horse and needs to be able to connect to your phone.

Don't place the heart rate sensor under the belly of your horse, the phone is then not able to make a proper Bluetooth connection

In the EI Potential app you can easily start a recording and stop a recording by the 'record' button.

From more detailed information, watch the 'How to' video on How to make a recording.

Watch the video on 'How to make a recording' to see in detail the steps required to make a correct heart rate recording of your activity.

To start measuring your horse on a daily basis with EI Potential and get analysis and feedback on a weekly basis, you need at home with your horse a heart rate sensor and a heart rate belt. Often the scientifically validated Polar Equine Belt for riding is used for this along with the Polar H10 sensor. Other Bluetooth sensors can also be used and/or Polar H10 sensor with other heart rate belts. We advice you at least to use equipment which is validated for its use for horses and use Bluetooth sensors with low-energy (BLE). The H7 sensor from Polar for example outdated and should be replaced by a H10 sensor for accurate recordings.

GPS Missing


If you rode indoors, GPS may not work. If you trained outside, check your phone settings:
• Make sure Location access is ON for EI Potential
• Enable Precise Location

Heart Rate Missing
 or no heart rate was recorded

Common reasons:

• The belt wasn’t tight enough

• The horse’s coat was too dry

• The battery in the sensor was empty

✅ Try tightening the belt, wetting the coat, or replacing the battery.

Heart Rate Too Low
 or irregular recorded

Low or irregular heart rate data often means the coat was too dry or too thick to have proper contact with the skin to collect the heart rate signals.
✅ Wet the coat well or use a water-based gel before training (for shaved horses; water-based gel might work better than water as coat is too short sometimes to hold water).

When heart rate is not showing in EI Potential

If EI Potential cannot detect your heart rate sensor (while it’s on your horse with a wetted coat), it may be caused by several issues.
Please check these in order to find and fix the problem.

1. Check if the sensor battery is empty

How to test the battery:

1. Remove the sensor from the heart rate belt.

2. Hold the sensor in your hand and place two fingers on the two metal buttons at the back — this will send out a Bluetooth signal.

3. In the EI Potential app, start a new Recording, then choose Continue to Sensor Check.

4. Look for the battery status in the top right corner.

   • If the battery status is shown (and is above 10%), the battery is fine.

   • If it says No Data, the heart rate can’t be measured with your fingertips — this is normal.

If battery status is shown and above 10%:

• Put the sensor back on the heart rate belt on your horse.

• Repeat the Sensor Check process to confirm you now see both heart rate and battery status.

• If both are shown → start your recording.

• If battery shows but no heart rate appears → your belt may be broken.
  Check for connection issues or replace the belt.

2. If no battery status is shown

This can mean either:

A) The battery is empty

• Replace the battery (check the correct battery type).

• Repeat Step 1 to confirm the sensor now shows in the Sensor Check menu.

• If heart rate appears after replacing the battery → you’re ready to record.

B) The sensor needs to be reconnected

If the new battery works but heart rate still isn’t showing, the sensor may have reset to factory settings.

To reconnect the sensor:

1. In the EI Potential app, go to Settings → Sensors.

2. Select the sensor with the issue and choose Forget Sensor.

3. Hold two fingers on the two buttons at the back of the sensor to activate it.

4. In the app, tap Add (+) Sensor — your sensor should now appear.

5. Add it, then follow the normal process to start a recording.
