At LifeQ, we strive to provide real-time, science-backed insights that empower you to optimize your health. Our advanced wearable technology is designed to deliver precise physiological data, but as with all optical sensors, certain factors can impact accuracy.
To ensure you get the most reliable data from your device, this guide outlines best practices for fit, maintenance, and usage—as well as factors that may influence readings.
LifeQ-enabled wearables use advanced optical heart rate sensing technology to measure subtle changes in blood volume beneath the skin. By emitting light and analyzing how it interacts with your circulatory system, your device can track heart rate, heart rate variability, and other vital metrics.
However, external conditions—such as movement, skin characteristics, and sensor positioning—can influence the data collected. Following the best practices below will help you maintain the highest level of accuracy.
• Snug but comfortable: The device should fit securely against your skin without being too tight or restrictive. A good fit allows the watch and skin to move together without gaps.
• Positioning matters: Wear the device above your wrist bone for the most stable readings.
• Silicone bands are best: Flexible materials like silicone provide a better fit than metal, leather, or nylon straps, which may shift during movement.
• Outside of the wrist preferred: For consistent readings, wear the device on the outer part of your wrist rather than the underside.
Pro Tip: During workouts that involve flexing or gripping (e.g., weightlifting, rowing), move the device slightly higher up the forearm to maintain contact.
Rinse the sensor with fresh water after workouts.Use a soft cloth to gently wipe away residue (avoid harsh cleaners). • • Let the device fully dry before wearing it again.
Your vascular system behaves dynamically, meaning muscle contractions and movement patterns can affect readings. In some cases, the device may pick up movement signals instead of heart rate.
High-impact activities like running may cause the sensor to mistake cadence for heart rate.
Cold weather can reduce blood flow near the skin, making it harder to detect heart rate.
Sudden wrist movements (e.g., push-ups, burpees) may create signal disruption.
Tip: If accuracy is critical, consider pairing your device with a LifeQ-compatible chest strap for high-intensity activities.
Select an activity profile that matches your movement type (e.g., running mode for jogging, cycling mode for biking).
Avoid using static activity modes (like elliptical) for dynamic movements.
Some exercises naturally interfere with optical heart rate tracking due to wrist positioning and blood flow restriction.
Weightlifting (gripping weights tightly can reduce circulation)
Rowing, Cycling, Hiking with Poles (pressure from handlebars or poles may affect readings)
Yoga, Push-ups, and Racket Sports (bending the wrist can disrupt sensor contact)
Solution: Adjust the watch position slightly higher on your forearm or use an external heart rate strap for these workouts.
Cold temperatures reducing blood flow
Large arm motions affecting sensor contact
Water creating gaps between the sensor and skin
✔ Ensure the device stays snug against your skin at all times.
✔ Warm up before swimming to improve blood flow.
Note: Optical sensors are less accurate in water. If precise heart rate data is needed, consider a chest strap designed for swimming.
Darker tattoos, intricate patterns, and heavily saturated ink can block optical sensors, leading to incomplete or inaccurate readings.
✔ For best results, wear the device on a tattoo-free area of your skin.
LifeQ wearables are designed to function across all skin tones. However, higher melanin levels may absorb more light, requiring the sensor to adjust brightness levels. This can lead to slightly higher battery usage but does not impact heart rate accuracy.
A simple reboot once a week can help refresh the system and prevent minor glitches.
Updates often include improvements for sensor performance and data accuracy. Ensure your device is running the latest firmware by checking your LifeQ app or syncing with your computer.
Make sure your height, weight, age, and fitness level are correctly entered. These values help personalize heart rate calculations and ensure more accurate insights.
To charge the wearable device:Plug the charging dock into a USB-A power adapter or computer.
Cradle Dock Charger: Snap your wearable device into the charging dock cradle with the watch buttons lining up on either side of the metal charging pins.
Flat Dock Charger: Place your wearable device onto the flat charger and ensure the charging contacts connect.
Tip: Check the device to ensure there is an indication on the screen that it’s charging.
Since it is important that you wear the device during sleep, it is recommended that:
The LifeQ-enabled device is charged in the evening while you are having your evening meal or taking a shower/ bath.
We recommend that you set an alarm on your phone as a reminder to put the LifeQ-enabled device back on after charging.
Solution: Please try to wear the LifeQ-enabled device at least 2 hours before and after sleep.
Pro Tip: It is recommended that charging takes place at a similar time every day.
Place your wearable approximately two finger spaces up your wrist.Ensure the sensor of the wearable (the bottom of the watch face) is placed squarely over your arm, unimpeded by your wrist, and not at an angle. Make sure your is fit snugly enough for a secure fit, without being so tight that it impedes blood flow to the area.
Pro Tip: Place your watch face down when you are not wearing or charging it. This will improve the battery life by ensuring that the LED lights stop flashing. • • Pro Tip: Moisture and light can impact the quality of the signal that the sensor receives so dry off your wearable if it gets damp.
Your LifeQ-enabled wearable is a powerful tool designed to provide science-backed health insights—but like any technology, its accuracy depends on proper use and best practices.
By ensuring a proper fit, keeping the sensor clean, using the right activity profiles, and staying up to date with software improvements, you’ll get the best possible data to support your health and performance goals.
