Frontier Pulse sets itself apart by offering unlimited measurements, immediate and actionable results, and the convenience of easy sharing with your physician. Unlike other apps, all anomalous measurements are reviewed by our medical experts, ensuring that you receive the highest level of accuracy and care. Additionally, our app offers the unique feature of setting reminders for regular monitoring, along with providing detailed weekly reports, making it an invaluable tool for managing and understanding your heart health.

Frontier Pulse is designed for users over 18 years of age. Since younger individuals tend to have higher heart rate variability (HRV), which is expected, there's a higher chance of receiving inaccurate results when utilizing Frontier Pulse for those under 18. As such, we do not recommend Frontier Pulse for users below this age threshold.

Failure to perform heart rhythm measurements accurately after exercising is due to vasoconstriction, the narrowing of blood vessels, which is a normal response to physical activity. This condition can make it challenging for the app to accurately measure your heart rhythm. If the quality of the measurement is deemed too low, or if the app is unable to start the measurement because it cannot detect a heartbeat, warming your hands and attempting the measurement again is recommended.

The heart rate displayed during the measurement is an estimated BPM based on the data collected in the last few seconds, making it an approximate value. The heart rate reported after the measurement is the exact count of heartbeats recorded, which explains any discrepancy between the two BPM values.

Regular heart rhythm: Indicates a detected regular rhythm.

Increased heart rhythm variability: Signifies a higher variability in heart rate, common in younger and physically active individuals, indicating a healthy heart response.

Extrasystoles (isolated or frequent): Refers to extra heartbeats originating from the heart's upper or lower chambers, often harmless but could indicate more serious conditions if frequent.

Tachycardia (episode): A faster-than-normal heart rate which might require medical attention.

Bradycardia (episode): A slower-than-normal heart rate, normal for some but potentially serious if symptomatic.

Dubious rhythm: Unclear results that suggest potential underlying rhythm disorders, necessitating further analysis.

Atrial fibrillation or flutter: An irregular heart rhythm that could indicate atrial fibrillation, associated with a higher stroke risk, advising consultation with a medical professional.

To share individual measurements or weekly/monthly reports (for Premium subscribers), access the respective sections in the app ('View results' for individual measurements, 'Reports' for aggregated data), select the measurement or report you wish to share, and choose 'Download or share the report' at the bottom of the screen. You can then select the preferred channel for sharing, such as email.

If you encounter issues when requesting a review of your measurement, please follow these steps within the app: Navigate to ‘Results’, select the desired measurement, and opt for ‘Request a review by a medical expert’. This service is available for a fee of €9.99 per measurement for Essential plan users, with reviews provided by our medical experts within 48 hours.

The primary reasons for receiving a 'Insufficient signal quality' result usually involve the camera not receiving a proper signal from your fingertip or movement during the measurement. To address this, try the following steps:

- Remove your smartphone's protective cover to ensure better contact between your finger and the camera lens.

- Apply gentle pressure on the camera with your finger. Too much force can distort the signal.

- If one finger doesn't work well, switch to another or adjust its position slightly on the camera lens.

- Ensure you are seated and relaxed during the measurement, avoiding any movement or talking, to minimize signal interference.

If these adjustments don't help, consider whether:

- Calluses or physical conditions of your fingers might be affecting the measurement. Try using a different finger or the base of your thumb, which might provide a clearer signal.

- Cold hands could be reducing blood circulation to your fingertips, making it harder for the app to detect the necessary volume changes in your finger tips. Warm up your hands before taking another measurement.

- Hand tremors are present; stabilizing your hands on a table or placing the smartphone on your finger instead of pressing your finger onto the camera might help.

If you continue to experience issues despite these troubleshooting steps, restart the Frontier Pulse app and attempt a new measurement, ensuring your finger is correctly positioned and you remain as still as possible.

For accurate heart rhythm measurements with Frontier Pulse, follow these tips:

- Ensure you are seated comfortably with your arms resting on a stable surface to avoid any unnecessary movement during the measurement.

- Lightly place your finger on the camera lens without applying excessive pressure. A gentle touch ensures the best possible signal.

- Remove any protective case from your smartphone as it might interfere with the camera's ability to accurately detect your heartbeat.

- Make sure your finger covers the lens completely but does not touch the flashlight to avoid overheating and potential discomfort.

- In cases where your smartphone has more than one camera, use the instructions provided within the app to identify which lens should be used for measurements.

Adhering to these guidelines will help ensure that your measurements are both accurate and consistent.

For smartphones equipped with multiple camera lenses, Frontier Pulse provides a helpful guide to determine the correct lens for heart rhythm measurements:

1. Start the measurement process in the app. If you encounter a 'Prepare' screen, follow the prompts until you reach the 'Find your camera' instruction.

2. On the 'Find your camera' screen, you will see a visual guide indicating which camera lens to cover with your finger. The correct lens will cause the on-screen circle to darken or turn red, indicating that your finger is properly placed. If you cover a different lens and the circle displays your surroundings, switch to another lens and try again.

3. Once you've identified the correct lens, proceed with your heart rhythm measurement as directed by the app, ensuring not to cover the flashlight with your finger to prevent overheating.

Following these steps will help you utilize the appropriate camera lens for accurate heart rhythm monitoring with Frontier Pulse.
