How do I choose the right size?

• Use our HAALE size guide to measure your finger, you will find it in the main menu.
• If you're between sizes, we recommend choosing the larger size.
• Remember, finger size can vary based on temperature and time of day.

Can I exchange my ring for a different size?
Yes! You can easily exchange your ring by registering a return through our Return Portal or by getting in touch at help@haalering.com

Will you offer larger sizes, like size 13?
Currently, the largest size is 12, and we don't have plans for size 13. However, trying the ring on the index or middle finger of the non-dominant hand (which tends to be slightly smaller) can help with fit.

With the HAALE smart ring, syncing your data to the Apple Health app is effortless.

To sync data from your smart ring to Apple Health, follow these steps:

• Ensure you have the HAALE app for your smart ring installed on your iPhone
  
• Open the app and pair it with your smart ring via Bluetooth.
  
• Open the Me Settings in the HAALE app.
  Click on the Apple Health and follow the steps described.
  
• You may be prompted to allow the app to share data with Apple Health. Grant the necessary permissions for the data you want to sync, like steps, heart rate, sleep, or activity.
  
• Once permissions are granted, your smart ring’s data (steps, activity, heart rate, etc.) will automatically sync to Apple Health. Open the Apple Health app to view the data.
  

Now, your smart ring data will be available in Apple Health for easier tracking and analysis.

HAALE Smart ring uses different technology to detect various health metrics

The red and green lights in a smart ring are typically used in photoplethysmography (PPG) sensors to measure various health metrics, such as heart rate and blood oxygen levels. Here’s the difference:

Used for Heart Rate Measurement
Why Green?: The green wavelength is better absorbed by hemoglobin in red blood cells, making it ideal for detecting pulse and heart rate.

Used for SpO2 (Blood Oxygen) Measurement
Why Red?: Hemoglobin absorbs red light differently when oxygenated or deoxygenated, allowing the sensor to calculate the oxygen saturation in the blood.

In summary, green light is used for heart rate monitoring, while red light helps measure blood oxygen levels.

For the best accuracy, wear the ring on your index, middle, or ring finger of your non-dominant hand. Ensure it fits snugly for optimal sensor contact.

With the HAALE health ring you can measure Activity levels, HRV, Blood oxygen, track your cycle, skin temperature, calories, sleep, heart rate, stress and much more.

Yes! The HAALE Ring is fully waterproof and build to withstand everyday activities, including swimming, showering, and intense workouts. No need to take it off!

Our Smart ring is fully dust-tight (6) and can withstand water immersion, typically up to 50 meters for 30 minutes (8).

Benefits:

Durability: Safe for swimming, showering, or exercising in the rain.

Convenience: No need to remove the ring for water-related activities.

Long-Term Use: Reliable performance even with prolonged water exposure.

Ideal for swimming, fitness tracking, and everyday wear without worrying about water damage.

We take customer privacy and data security very seriously. All customer data is stored exclusively within the customer's app. We do not store, share, or transmit any customer information to external servers or third parties. This ensures that your personal information remains secure and under your control at all times.

Yes! HAALE II is CE-certified, as required.

Under normal use, HAALE II lasts 5–7 days.

More frequent tracking (like continuous activity monitoring) can shorten battery life slightly.

• Around 1 hour for a full charge.
• Always charge the ring fully before first use.

• Remove any protective plastic from the sensors.
• Place it on the magnetic charger and ensure the red light appears (green means it's fully charged).
• If the issue persists, please contact us for assistance at help@haalering.com

• HAALE II is our latest model, featuring improved sensors, longer battery life, a new app, and more advanced features for more accurate tracking.
• HAALE I has a simpler design, works with a different app, and offers more basic tracking.

There’s no dedicated airplane mode, but turning off Bluetooth on your phone will stop the ring from transmitting data until Bluetooth is turned on again.

Yes! The ring stores data and syncs it to the app when the phone is nearby and Bluetooth is enabled.

You can not pair our ring with Natural cycles, but you can follow in the app when your next period is due and when you have ovulation.

The ring only shows one decimal temperature data.

The HAALE ring track stress levels using a combination of biometric sensors and advanced algorithms. These devices analyze various physiological indicators to assess stress responses, helping users monitor and manage stress effectively.

By utilizing HRV, Blood oxygen levels, skin temperature tracking, and motion sensors, our smart ring provide a non-intrusive way to monitor stress and improve overall well-being.

HAALE measures sleep using biometric sensors and algorithms to track physiological and movement metrics by using below sensors:

PPG Sensor: Measures heart rate and variability using infrared light.

Accelerometer & IMU: Detects movement to identify sleep stages.

Temperature Sensor: Monitors body temperature fluctuations.

SpO2 Sensor: Tracks blood oxygen levels to detect irregularities.

Sleep Stages:

Awake: Excessive movement and higher heart rates.

Light Sleep: Shallow sleep with reduced heart rate and movement.

Deep Sleep: Restorative stage with minimal movement.

REM Sleep: Dreaming and cognitive processing, detected via HRV.

Metrics are analyzed with machine-learning algorithms in the HAALE app, offering a sleep score.

HAALE smart ring measures steps and activity using a 3D accelerometer to track motion patterns, filtering out non-step movements. It analyzes stride, cadence, and intensity to estimate steps and physical activity. Our Smart ring also incorporate heart rate sensors and MET calculations to gauge exertion levels and calorie burn. 

Step Measurement:

Accelerometer detects walking/running motions.

Algorithms filter movements for accurate step counting and estimate stride length.

Activity Tracking:

Motion Analysis categorizes activities like walking or running.

MET Calculation estimates energy expenditure, that gives you the calorie burn

Heart Rate Monitoring tracks activity intensity and calories.

Sleep Stages:

Awake: Excessive movement and higher heart rates.

Light Sleep: Shallow sleep with reduced heart rate and movement.

Deep Sleep: Restorative stage with minimal movement.

REM Sleep: Dreaming and cognitive processing, detected via HRV.

Metrics are analyzed with machine-learning algorithms in the HAALE app, offering a sleep score.

HAALE smart ring uses sensors (like accelerometers, heart rate monitors, and SpO2 sensors) to track movement, heart rate, and other health metrics. The data is processed by the ring's microprocessor and synced to the HAALE mobile app via Bluetooth for analysis. HAALE use machine learning to improve accuracy over time. The HAALE ring has a small, long-lasting battery with a lifetime of 5-7 days without charging.
