FAQ

The Leep Ring is a smart ring that tracks sleep, heart rate, heart rate variability (HRV), estimated blood oxygen (SpO₂), temperature and activity. It costs £199 as a one-time payment with no subscription or monthly fees.

The Leep Ring costs £199. This is a one-time payment with no ongoing subscription fees. The Leep app is free and there is no subscription to unlock features.

No. The Leep Ring has no subscription, no monthly fees and no hidden costs. You pay £199 once, and the Leep app and its tracking features are included - there are no paid tiers.

Leep and Oura track many of the same categories of sleep and wellness data, including HRV, SpO₂ and estimated sleep stages. Leep costs £199 with no subscription, while the Oura Ring requires an ongoing monthly membership to access full features. This is a comparison of features, not of measurement performance — the two devices have not been tested against each other.

We send you a free sizing kit before dispatching your ring, so you have time to test different sizes and fingers - ideally wearing your preferred size overnight, as fingers can swell with warmth and activity.

To confirm your size, click through to your order details from your order confirmation email and select "Change product options" to choose your perfect size. We will then dispatch the ring straight away.

Tips: go with the larger size if you are between sizes. The ring's resin inner lining is slightly stickier than the sample, so it will feel a fraction more secure to remove than the sample you tested. If the sample leaves an indent when cold, go up a size.

Place the ring in the charging case with the sensor bumps facing downward into the magnetic pins. Remove the ring protector first — it can prevent the pins from making proper contact. You'll see a slow green blinking LED on the ring when it's charging correctly. The case itself charges via the included USB-C cable into any USB power source (a power adapter is not included), and holds up to 60 days of backup charge once full.

If your ring won't charge at all, please see "My Leep Ring is not charging" in the Troubleshooting document — the most common cause is a small clear plastic protector left around the charging pillar inside the case.

Before anything else, look inside your charging case and remove the small clear plastic ring sitting around the charging pillar. It's transparent and easy to miss, but if it's still in place your Leep Ring simply cannot charge. Lift it off, pop your ring back in, and you should be good to go.

The ring uses PPG (Photoplethysmography) — light is shone through the skin to measure heart rate, HRV and blood oxygen. The LED only activates during active measurements, not continuously.

• Green LED: the ring is measuring heart rate (every 10 minutes) or HRV (every 60 minutes).
• Red LED: the ring is measuring blood oxygen saturation / SpO2 (every 30 minutes).

If the green LED stays on continuously rather than pulsing briefly, this may indicate a software issue — please update the app to the latest version.

The Leep Ring tracks sleep, heart rate (HR), heart rate variability (HRV), temperature, and activity. All of these are core metrics that influence how rested you feel. We follow World Sleep Society guidelines, focusing on trends, not perfection. We don’t present you with overwhelming data – just what you need to know to help you sleep better.

The app supports iOS 15+ and Android 8.0+, and is available in English, French, French Canadian, German, Spanish, Dutch, Italian, Polish, Slovenian, Swedish, Russian, Ukrainian, Portuguese (Brazilian), Japanese, Korean, and Chinese (Simplified and Traditional).

A few simple habits make a real difference to long-term battery health:

Charge before it runs low. Try to charge your ring when it reaches around 20-30% rather than waiting for it to approach empty. Deep discharge (regularly dropping below 10%) is one of the fastest ways to shorten battery lifespan.
‍
You don't need to reach 100% every time. Charging to 80-85% and stopping is actually better for the battery than always waiting for a full charge. Stopping the charge when you head out for the day is a good habit.
‍
Don't leave the ring in the charging case overnight every night. The case is designed for top-ups, not as a permanent dock. Sitting at 100% charge for extended periods gradually reduces battery capacity over time.
‍
Charge the case, then unplug it. Treat the charging case like a power bank: charge it to full, unplug it, and use it on the go. Leaving it permanently plugged into a wall socket accelerates wear on the case battery.
‍
Keep it away from heat. Avoid leaving your ring or charging case in direct sunlight, hot cars, or steamy bathrooms for extended periods. Heat is the single biggest accelerant of battery degradation.
‍
Keep your app updated. App and firmware updates often include battery optimisations that can improve ring life between charges.

The Leep Ring can run for over a week on a single full charge under typical conditions. In practice, we recommend charging every 3-4 days, keeping your ring between around 20% and 85% where possible. Regularly letting it drain to empty, or always charging to 100% and leaving it there, gradually reduces battery capacity over time. Short, regular top-ups are better for your ring's long-term health than infrequent full cycles.

If you're seeing significantly shorter battery life, update the app first — a background sync bug introduced in late May 2026 caused excess drain for some users and has since been fixed.

If battery life is still well below normal after updating, see "My Leep Ring battery is draining too quickly" in the Troubleshooting document for the full diagnostic steps.

‍

A no-quibble return within 30 days of receiving your ring. Unpair it from the app before returning and include your order number. UK returns get a pre-paid label; international returns are at the buyer's cost unless the ring is faulty, in which case we cover shipping regardless of location. Refunds are processed within 5–10 working days of receiving the return.

We'll contact you as soon as we're aware of a delay. You can switch to an available colour and receive your ring straight away, wait for your colour to restock, or cancel for a full refund — we regularly offer a goodwill discount for stock delays.

Yes — contact support@leephealth.com to arrange an exchange. UK customers receive a pre-paid return label; international customers cover return shipping.

The index or middle finger gives the best PPG sensor signal quality due to larger blood vessels. The ring finger and pinky also work well. If you plan to wear the ring during activities, choose a finger where the ring stays snug without spinning freely.

If you wear the ring on your index finger, the app will pick up phone interactions such as swiping, which can be useful for detecting night time waking.

• Orange circle with a percentage: ring connected, showing battery level.
• Spinning white semi-circle: ring actively syncing data.
• Red circle: ring not connected — try closing and reopening the app.

For persistent connection problems, see the Troubleshooting document for the full reconnection steps.

Go to Your Account > Export Your Data for a CSV containing all your sleep segments, heart rate, HRV, SpO2, temperature and step data — open it in Excel/Numbers, or upload it to an AI assistant for a readable analysis.

This is different from the automatic cloud backup that protects your account history — see the Troubleshooting document for backup and device-transfer guidance.

The most common cause is the ring not detecting a transition out of sleep mode when you wake during the night (known as WASO — Wake After Sleep Onset detection), something we're actively improving with a Sleep Correction Layer currently in development. Syncing the app as soon as you wake helps the algorithm process the full night correctly.

If gaps are frequent or severe, see "My sleep data is missing or incomplete" and "My heart rate graphs have gaps" in the Troubleshooting document for fit- and battery-related causes.

If you are an Android user and your sleep duration looks roughly double what it should be (for example, 14 hours when you only slept 7), this was caused by a timezone bug that has now been fixed in the latest Android app update. Please update to the latest version from the Google Play Store. If the issue persists after updating, a full uninstall and reinstall of the app will clear any legacy cached data.

Yes. The ring needs your heart rate and movement to drop to sleep levels to classify a nap, so a light doze with background noise is harder to detect than a proper lie-down. Naps within about 4 hours of your main sleep can sometimes be missed while the algorithm finishes processing the night. Syncing right after waking from a nap helps.

Suggested bedtime is calculated from your historical sleep patterns, so if your data baseline was affected by a software issue, the suggestion may be off. After updating the app and a few days of clean data, it will recalibrate.

The Leep Ring tracks activity that can affect your sleep. We sync with Apple Health and Google Fit to combine workout data and improve sleep insights.

Steps are estimated from arm swing and accelerometer motion combined with your height, weight and age (fill these in under Your Account > Your Profile for best accuracy). Activities that restrict arm swing — pushing a pram, cycling, rowing, weightlifting — will show lower step counts. Live Heart Rate gives a better picture of exertion for these activities than step count alone.

Yes — it's waterproof for swimming (see the waterproof question above), and Live Heart Rate (available on both iOS and Android) gives an accurate effort reading for cycling, where arm-swing-based step counting won't. Several users have reported successful use on 4–5 hour rides with minimal battery impact.

It tracks activity that affects your sleep and syncs with Apple Health and Google Fit to combine workout data with sleep insights. VO2 max isn't currently supported — it requires exercise intensity and respiratory modelling we're not yet doing, though it's on our longer-term roadmap.

Yes. Apple Health integration is live on iOS, syncing sleep, movement and vitals. Google Health Connect is available on Android. Both let your Leep data flow into your wider health picture alongside other devices and apps.

At just 2.22mm thick at its thinnest, the Leep Ring is ultra-thin and lightweight. Most people stop noticing it after a short time. It’s made from aerospace-grade titanium with a smooth, hypoallergenic inner lining, designed for 24/7 comfort.

For people who want better sleep without pressure, many users say the Leep Ring feels worth it. They often report improved sleep and steadier daily energy,  without feeling stressed or judged by their data. It’s designed to support healthier habits quietly with a focus on rest, not perfection.

Every Leep Ring set includes a Leep Ring in your chosen colour, a Charging Case, a USB Type-C charging cable and two ring protectors (one clear, one black). So you have everything you need to get started.

Please note: the ring protectors must be removed before placing your ring in the charging case, as they can prevent the magnetic pins from making contact.

Finger size changes throughout the day, which can occasionally make a ring harder to remove. Try wetting your finger with mild soap or cold water and gently twisting it off, or raising your hand above heart level for a few minutes to reduce swelling. Cooling your hand in a bowl of cold water with ice, or using the string/floss method, can also help. If you experience pain, numbness or increasing discomfort, seek medical assistance promptly.

You can own more than one ring, but only one can be connected to the app at a time. Family members aged 18 or over can use your ring once it has been reset in the app; it will take up to 7 days to recalibrate to a new wearer. The Leep Ring is not suitable for under-18s, as it is designed for adult physiology.

The Leep Ring is CE marked and complies with the UK and EU regulations that apply to it, covering general product safety, radio equipment, electromagnetic compatibility and battery safety. The battery is certified to IEC 62133. The Leep Ring also meets US FCC requirements, Australian and New Zealand market access requirements (RCM), Japan’s MIC radio certification and Canada’s ISED certification (formerly Industry Canada). Leep Health Limited is registered for UK WEEE, battery producer responsibility and packaging waste.

The Leep Ring is a wellness device, not a medical device, and has not undergone medical device certification. It is designed to support everyday sleep and wellbeing tracking, not to diagnose, treat or monitor any medical condition.

The Leep Ring is ultra-thin at just 2.22mm at its thinnest, designed for comfortable 24/7 wear.

Depending on the size, the weight of the Leep Ring ranges between 2.5g to 6g.

The outer shell is aerospace-grade titanium (Ti-6Al-4V) for strength, light weight, corrosion resistance and biocompatibility, with a seamless hypoallergenic epoxy-based resin inner lining and a PVD coating. It's one of the thinnest smart rings on the market at 2.22mm at its thinnest point, weighing between 2.5g and 6g depending on size.

The Leep Ring isn’t a medical device, but it can help you notice patterns and changes in your sleep and recovery over time. It is not intended to diagnose, treat, cure, monitor, or prevent medical conditions or illnesses. You should not make any changes to your medication, nutrition, or workouts without first consulting your doctor or another medical professional.

Yes, the Leep Ring continues tracking your data even when you’re offline. An internet connection isn’t required for tracking. When your ring reconnects to  your phone via Bluetooth, the Leep App will sync and process the data as usual.

The Leep Ring can track and store up to two weeks of data without being connected to your phone. For the most complete and up-to-date insights, we suggest syncing once or twice a day when it’s convenient.

Download the Leep App and follow the guided setup — always pair through the app rather than your phone's Bluetooth settings. Bluetooth must be enabled for syncing, though the ring keeps collecting data even when Bluetooth is off and syncs automatically once it's back on. The ring uses Bluetooth Low Energy (BLE), so it may not appear in your phone's Bluetooth settings menu — this is normal.

Yes. The Leep Ring is rated IP68 and water resistant up to 50 metres, so it's safe for swimming, showering, washing your hands and rain. We don't recommend scuba diving or submersion over 12 hours, and the ring should be removed before saunas, baths or jacuzzis.

Tracking heart rate while swimming is an industry-wide PPG challenge — water interferes with the light signal, and swimming heart rate naturally reads 10–15bpm lower than equivalent land-based effort. A silicone finger guard over the ring can improve sensor contact in water, and using Live Heart Rate before getting in the pool gives better results than background sampling.

The titanium body resists scratches well, though light surface marks can appear over time with daily wear, as with most jewellery. To minimise cosmetic wear: wear it on your non-dominant hand, avoid wearing other rings next to it, and remove it for high-friction activities like weightlifting.

The Leep Ring is designed for adults. It is not suitable for anyone under 18, because the sleep and physiological patterns it interprets are based on adult physiology. Leep accounts are for users aged 18 and over.

‍

Yes. The ring updates to your local time automatically when it reconnects to the app over Bluetooth in a new time zone, provided Bluetooth is enabled and your phone's OS is up to date.

Yes, your data is secure and private. We encrypt everything, so your information is protected both on your phone and in our secure cloud storage.

We don't sell your data. Ever. There are no advertisers and no hidden data sharing.

You’re always in control:

• Export your data at any time
• Delete your data whenever you choose
• Full access to everything we collect
• Opt in or out of any sleep research studies we take part in
• GDPR-compliant and transparent by design

Research participation is always optional. If we contribute to sleep studies, it’s to improve our product and advance sleep science, but only with your explicit consent. We also keep our privacy policy in plain English, so it’s easy to understand how your data is used.

Leep uses intelligent algorithms to analyse your sleep patterns and provide personalised insights. It’s best thought of as smart pattern recognition, rather than artificial intelligence making decisions for you.

Yes — you can work towards goals like improving sleep consistency, reducing stress, or boosting energy, with progress shown via simple charts and gentle, optional nudges based on your patterns.

Yes you can wear your Leep Ring only at night and still get useful sleep insights. Wearing it during the day helps build a more complete picture of how activity, stress, and recovery affect your sleep. So for deeper personalisation we recommend 24/7 wear, but it’s entirely up to you.

Clean it about once a week: gently wipe the sensor bumps with a soft cloth, or rinse with a little mild dish soap and water, drying thoroughly before wearing again. The ring and Charging Case contain batteries, so dispose of them as e-waste via your local electronics recycling point when no longer needed.

HRV is the natural variation in time between heartbeats, used as a signal of how your body copes with stress, recovery and overall balance — best read as a trend over time rather than a single number.

The ring samples heart rate every 10 minutes in the background; the app shows the most recent sample, not a live figure. In our own testing, static readings agreed with a Polar H10 chest-strap ECG to within ±3 BPM in 97% of paired readings.* Readings taken during movement are less precise, and fit, circulation and individual physiology all affect the signal, so trends over time are more useful than any single reading. Live Heart Rate is available on both iOS and Android.

* Leep internal comparison testing against a Polar H10 chest-strap ECG, conducted in March 2025 with 10 participants at rest. This is internal testing, not an independent or clinical validation study.

Yes. It uses low-power Bluetooth Low Energy, connecting only when you open the app or at set intervals, unlike devices with constant connectivity such as earbuds or smartwatches. Bluetooth activity stays below 1% of the day, giving significantly lower EMF exposure than most Bluetooth wearables.

Yes. The Leep Ring is lightweight and designed to be worn 24/7 including during sleep. Customers consistently describe it as so light they forget they are wearing it.

Yes. The Leep Ring ships from the UK with free UK delivery. It is also available internationally.

The Leep Ring tracks sleep duration and estimated sleep stages, heart rate, heart rate variability (HRV), estimated blood oxygen saturation (SpO₂), skin temperature, steps, distance and active minutes.

The Leep Ring is a smart ring with no subscription that tracks sleep, HRV, SpO2 and activity for a one-time cost of £199. All app features are included with no monthly fees.

The Leep Ring costs £199 and includes sleep tracking, HRV, SpO2, heart rate and activity tracking with no subscription. It has been featured in Forbes, Wired and TechAdvisor.

Yes. The Leep Ring tracks sleep, HRV, heart rate and recovery similar to Whoop, but as a ring rather than a wrist band. Unlike Whoop, there is no monthly subscription - you pay £199 once.

The two ring protectors guard the ring's PVD finish during gardening, gym work, cleaning or other heavy manual activity. Remove the protector before charging and before sleep, so the sensors keep the best possible contact with your skin.

Yes - the Leep Ring ships from the UK and is available internationally.
