Frequently asked questions

Try these steps in order:

1. Make sure your ring has some charge — a fully flat ring won't broadcast
2. Toggle Bluetooth off and back on on your phone
3. Close the app fully and reopen it
4. Make sure no other phone is already connected to the ring — it can only pair with one device at a time
5. If it still doesn't appear, restart your phone and try again

Yes — signing up with your email address is free and lets the app store and sync your health data across devices.

For accurate calorie, heart rate zone, and activity readings, enter your personal details in the app:

1. Go to the Home page
2. Tap in the top left
3. Select Profile
4. Enter your age, height, weight, and gender

The app uses these to calculate your personal heart rate zones, calorie burn, and fat burn thresholds.

Heart rate zones are calculated automatically once you've entered your age in your profile — the app uses standard max heart rate formulas to set your fat burn, anaerobic, and limit zones. You don't need to configure these manually.

The Quantum Ring app can sync your activity, sleep, and heart rate data with Apple Health (iPhone) or Google Fit (Android):

1. Tap Me in the bottom right
2. Tap Settings
3. Look for Health Connect or Third-Party Apps and enable the sync
4. Follow the permission prompts to authorise the connection

1. Go to the Home page
2. Tap in the top left
3. Tap Goal Setting
4. Enter your daily Steps, Calories and Distance targets
5. Press Save

Your progress toward the goal is shown on the Activity screen each day.

Your ring tracks movement automatically throughout the day. To record a specific workout with full detail (duration, calories, heart rate zones, fat burn time):

1. Tap Go in the Sport Record card on the homepage
2. Select your workout type (run, walk, cycle, etc.)
3. Tap Start — the ring will begin a live session
4. Tap Stop when you're done to save the session
5. Review your fat burn duration, heart rate, calories burned and more

Sleep tracking is on by default. Simply wear your ring to bed and the app will automatically detect your sleep and record your sleep stages, HRV, SpO₂, and body temperature overnight.

Your sleep summary will be visible in the Sleep tab the next morning after the ring syncs to your phone.

You can wear the ring on any finger. For best sensor accuracy, wear it with the sensor panel on the inside of your finger (facing your palm), and make sure it fits snugly without being tight. The index or middle finger tends to give the most consistent readings.

1. Tap Me in the bottom right
2. Select Gesture Selection
3. Choose the gestures you want to enable

1. Tap Me in the bottom right

• Heart rate (continuous, 24/7) and heart rate zones during workouts
• HRV (heart rate variability) — measured overnight
• Sleep stages: deep, REM, light, plus a sleep score
• Blood oxygen (SpO₂)
• Body temperature (nightly min/max)
• Stress levels — all-day continuous tracking
• Fat burn duration during exercise
• Steps, distance, and active calories

Data is stored on the ring and syncs to the app when the two are connected via Bluetooth. If data isn't appearing:

1. Open the app — this triggers a sync
2. Make sure Bluetooth is on and the ring is in range
3. Pull down to refresh on the Home screen

Overnight sleep data typically syncs within a minute of opening the app in the morning.

Your Quantum Ring comes with two cables in the box:

• Ring cord — plugs directly into the ring
• Case cord — charges the case, which can then charge the ring wirelessly

You can charge the ring either directly with the cord, or by dropping it into the case. The case holds multiple full charges — ideal for travel.

The lights are the ring's sensors working — this is normal:

• Red light — the blood oxygen (SpO₂) sensor is active
• Green light — the heart rate sensor is active

You'll typically see them flash during workout sessions or when the ring takes a background reading.

Up to 7 days with light daily use. If you're tracking intensive workouts every day, expect 3–4 days between charges. Sizes 9 and below have a slightly smaller battery, so battery life may be a little shorter.
