Key takeaways

5 points
  • The Leep Ring is $199 one-time in the US (£199 in the UK) with a free app and no paid tiers41.
  • It tracks sleep and estimated sleep stages, heart rate, HRV, skin temperature, steps and estimated blood oxygen; in the background it samples heart rate every 10 minutes, SpO2 every 30 and HRV every 602.
  • Battery is up to 8 days per charge, and the included charging case holds 60+ days of backup power1.
  • Leep says the ring is a wellness device, not a medical device, and is not intended to diagnose, treat or monitor any medical condition2.
  • We found no independent polysomnography (sleep-lab) validation of the Leep Ring; its only published accuracy figure is its own 10-person heart-rate test2. See what sleep rings can and can't measure.

What the Leep Ring is

Leep is a screenless titanium smart ring from Leep Health, a UK start-up. It pairs with a free app on iOS 15+ and Android 8.0+, and Leep states there is no subscription and no paid tier for extra features1.

The pitch is simple: most of what a premium sleep ring tracks, for a lower one-time price. Leep's own FAQ is candid that this is "a comparison of features, not of measurement performance" and that Leep and Oura "have not been tested against each other"2.

Price and what's in the box (checked Oct 2026)

Leep lists the ring at $199 as its official US list price (August 2026) and £199 on its UK shop page, which we read on Oct 14, 202641. That is the whole cost: the app and its tracking features are included2.

  • In the box: the ring, a charging case, a USB-C cable and two ring protectors; a power adapter is not included2.
  • Finishes: Starlight Silver, Midnight Blue and Moonlight Gold1.
  • Sizes 6 to 14, with a free sizing kit sent before the ring ships; sizing kits cannot be returned13.

Sensors and what it tracks

The ring uses photoplethysmography (PPG): a green LED for heart rate and HRV and a red LED for blood oxygen. Steps are estimated from an accelerometer plus your height, weight and age, and there is a skin temperature reading2.

Background sampling is periodic rather than continuous: heart rate every 10 minutes, SpO2 every 30 minutes and HRV every 60 minutes, with a Live Heart Rate mode for workouts2. Data syncs to Apple Health and Google Health Connect, and you can export everything as a CSV2.

  • Tracked: sleep duration and estimated stages, heart rate, HRV, estimated SpO2, skin temperature, steps, distance and active minutes2.
  • Not offered: VO2 max (Leep says it is on a longer-term roadmap)2.
  • Leep's only accuracy figure: resting readings within ±3 bpm of a Polar H10 chest strap in 97% of paired readings, from internal testing with 10 people in March 2025, which Leep itself says is "not an independent or clinical validation study"2.

Battery and charging

Leep quotes up to 8 days per charge and 60+ days of backup power in the case1. In practice it recommends topping up every 3 to 4 days and keeping the battery between about 20% and 85% to protect long-term capacity2.

Leep's FAQ also discloses a background-sync bug from late May 2026 that drained batteries faster for some users and says it has been fixed in an app update2.

Build, fit and water resistance

Leep says it processes data on-device and offers optional encrypted backup1, and the ring stores up to two weeks of data without a phone connection2.

  • Titanium (Ti-6Al-4V) shell with a hypoallergenic resin lining, 2.22 mm at its thinnest, 2.5 to 6 g depending on size2.
  • IP68, water resistant to 50 m; Leep advises removing it for saunas, baths and hot tubs2.
  • Not for under-18s: Leep says its algorithms are built on adult physiology2.

Warranty and returns

The shop page lists a 1-year warranty and a 30-day return policy1. Returns must be within 30 days of receipt, unpaired from the app, with all accessories and packaging; refunds go back to the original payment method within 5 to 10 business days3.

Outside the UK, you pay return shipping unless the ring is defective, damaged or not as described, and for a change-of-mind return the shipping cost is deducted from the refund. Only one return or exchange per item is allowed3.

Where it falls short

The honest list, before you buy:

  • No independent sleep-lab validation yet. Oura has several polysomnography studies (many Oura-funded); Leep has none we could find. See the evidence explainer.
  • Periodic background sampling (every 10, 30 and 60 minutes) rather than the continuous or high-frequency readings some rivals advertise2.
  • Young software. Leep's own FAQ lists a since-fixed Android timezone bug that doubled sleep totals, missed night-time wake-ups (a correction layer is still in development) and naps that can be missed near main sleep2.
  • Fewer extras: no VO2 max, and Leep's feature list doesn't mention cycle tracking, which the four rivals in our comparison all advertise.
  • Return shipping is on you outside the UK3.

Who it's for, and who should pick something else

Pick Leep if you want a light, comfortable ring for sleep timing, consistency and overnight heart-rate and HRV trends, and you would rather pay once than keep paying a membership. Our side-by-side comparison has the numbers.

Pick a rival if you want the most published validation work (Oura Ring 4, with a membership), the longest battery (RingConn Gen 2 quotes 10 to 12 days), deep Samsung phone integration (Galaxy Ring), or features Leep doesn't list, such as cycle insights.

And if you snore loudly, stop breathing at night or wake up exhausted, a consumer ring is not the answer. Obstructive sleep apnea is diagnosed with polysomnography or a home sleep apnea test ordered by a clinician6, and products marketed only for general wellness generally fall under FDA's low-risk wellness policy rather than device clearance5.
