Renpho has ventured into the extremely aggressive world of health trackers with the discharge of its first-ever sensible ring — the Renpho Lynx.
All that, and it’s fairly priced for a wise ring ($229) and doesn’t require a subscription. On paper, the Renpho Lynx appears prefer it might make its approach into our information to the greatest sensible rings — however can it dwell as much as our expectations and ship on efficiency? We had been eager to seek out out.

The Renpho Lynx is available in two shade choices, black carbon and silver titanium, and is out there in eight sizes (6 – 13). In case you are uncertain concerning the appropriate match, you’ll be able to request a sizing equipment earlier than buy — this prices round $2 to $4 (relying on the retailer), which might then be later deducted from the value of the ring. The vary of customization right here could not sweep you off your ft, however there are sufficient choices to swimsuit a comparatively big selection of potential customers.
Our testing unit got here in silver titanium, dimension 12. We have now combined emotions about its design, to say the least.
On the plus facet, the Renpho Lynx feels very mild but surprisingly sturdy. We examined it for about three weeks, exposing it to harsh winter circumstances and a spread of various exercises, and it has not sustained a single scratch. That is spectacular, given that the majority sensible rings we examined confirmed indicators of wear-and-tear within the first few weeks of testing. The Renpho Lynx could be very sensible in its design, making it a superb choose for many who do contact sports activities or a variety of handbook dealing with all through the day.
That is the place the nice issues finish, although.
Most significantly, we didn’t heat to the somewhat “masculine” and utilitarian appears of our Renpho Lynx. On the subject of sensible rings, model and look do matter lots — they’re nonetheless a bit of jewelry on the finish of the day. Many individuals put on them once they want one thing sleeker and extra elegant than a chunky health watch, and sometimes to enhance work apparel or formal clothes. The Renpho Lynx, nevertheless, appears unappealingly primary and, dare we are saying, low cost.
We didn’t discover it notably comfy to put on, both. Although mild, this sensible ring felt clunky and unpleasantly uneven on the within. Even after three weeks of sporting it, we nonetheless cannot get used to its presence on our finger. The Renpho Lynx can also be comparatively thick — it measures round 3.04 mm in width. To place that into perspective, the Oura Ring Gen 4 is roughly 2.88 mm vast, whereas the width of the Ultrahuman Ring AIR can measure as little as 2.45 mm.
Renpho Lynx: Options
- The app is primary, but it surely doesn’t require a subscription
- Tracks coronary heart fee, sleep, stress, steps, energy and extra
- Comes with a transportable charger case
The Renpho Lynx has no show, in order is the case with all screenless wearables, it might solely work when it’s related to the app first. In contrast to many others, nevertheless, it doesn’t require a subscription to take action.
The Renpho Well being app is totally freed from cost and is out there to each iOS and Android customers. That is the place you’ll be able to entry all the stats collected by the sensible ring, reminiscent of your step depend, energy burned, sleep size and high quality, coronary heart fee and HRV (coronary heart fee variability), stress ranges, SpO2 (blood oxygen) and menstrual cycle predictions.
Every morning, the Renpho Lynx will then use these knowledge factors to calculate your Well being Index — a each day evaluation of your well being and health standing, measured in proportion factors. Whereas this type of a inexperienced mild/crimson mild system is probably not overly scientific, it’s easy and simple to know — to not point out useful for health novices who could not but have a superb understanding when to push on with intense train and when to take a much-needed relaxation.
That stated, we aren’t huge followers of the Renpho Well being app. Sure, it feels “clear” and simple to navigate, but it surely lacks nuance or any genuinely helpful life-style steering. We had been notably dismayed by the each day tip part that accompanies your Well being Index — it’s normally quick, overly common and devoid of any sensible utility (“Good effort! Attempt to discover issues that make you are feeling good”). As such, the Renpho Lynx is probably not a superb possibility for health novices or those that require a deep understanding of their well being indicators and post-exercise restoration.
It isn’t all doom and gloom with the Renpho Lynx, although. One function that scored extremely in our books is its moveable charger case, which turned out to be an absolute lifesaver for storing and charging the ring on the go. It’s compact and moveable, however not so small that it’s prone to get misplaced within the backpack someplace or fall out of your pocket by chance. We’d like to see extra sensible ring manufacturers comply with swimsuit in that regard.
Renpho Lynx: Efficiency
- 7 to 12 days of battery life
- Inconsistent monitoring accuracy
- No main app connectivity points
In keeping with Renpho, the Lynx comes with roughly 7 to 12 days of battery life, and the charging case can add one other seven days on high of that. That declare rings largely true. Our testing unit would final roughly eight to 9 days on a single cost, with at the least three hour-long coaching periods recorded per week. Since real-time exercise monitoring could be very energy-intensive, it’s truthful to imagine that the Renpho Lynx would in all probability final for much longer with out it.
That stated, there is no such thing as a possibility so as to add exercise logs retrospectively, as is the case with most different sensible ring fashions. The Renpho Lynx additionally doesn’t have an computerized exercise detection. This can be a huge oversight — the elevated coronary heart fee from train can then be simply misconstrued as an indication of stress, and disrupt your total readings within the course of.
Subsequent, the monitoring accuracy. That is the place the Renpho Lynx suffered a very dangerous blow in our exams. Nonetheless, this must be seen within the context of how we measured it. Good rings, the Renpho Lynx included, normally don’t produce steady coronary heart fee measurements in the best way health watches do. Subsequently, it isn’t truthful to validate them utilizing our “go-to” technique for testing wrist-worn wearables, which is to put on them alongside a extremely exact chest-strap coronary heart fee monitor after which evaluate the 2 units of knowledge.
As an alternative, we resorted to evaluating our Renpho Lynx to the medically-graded Whoop MG band and the premium Oura Ring Gen 4 sensible ring. Each of those two screenless health trackers have proven us a superb diploma of accuracy up to now, however once more, we won’t vouch for them being appropriate 100% of the time.
Even so, the discrepancies had been simply too huge to brush off. The Renpho Lynx did produce comparatively correct coronary heart fee measurements during times of relaxation or low-intensity, steady-state cardio train, true, however anything would simply throw them off the mark. With Excessive Depth Interval Coaching, the center fee measurements had been downright unreliable.
The sleep high quality assessments didn’t impress with their accuracy, both. The Renpho Lynx was usually good at choosing up after we fell asleep, but it surely appeared to have a tough time detecting after we awakened. One time, we had been mendacity awake and immobile within the morning, and that was in some way sufficient to trick our sensible ring into pondering that we had been asleep. Not simply that, however we had been additionally supposedly within the deep sleep stage. This isn’t the norm, both — each the Oura Ring Gen 4 and Whoop MG marked that interval as us being awake.
Lastly, the Renpho Lynx appeared to have a slight tendency to overestimate our step depend and energy burned. In all equity, although, that appears to be the case with most sensible rings.
The app connectivity, then again, works exceptionally effectively. We have now examined sufficient sensible rings to know that they are often very temperamental in that regard, both by disconnecting from the app or struggling to sync the information for no obvious purpose. This sensible ring, nevertheless, didn’t trigger us a single connectivity challenge.
True, it took us a superb few seconds every morning to determine the app connection, however once more, that is one thing to be anticipated from a tool this small.
Renpho Lynx: Consumer opinions
On the time of scripting this overview, each Renpho‘s and Amazon‘s buyer opinions positioned the Renpho Lynx at a 4.4 out of 5 stars score. This sensible ring tended to be praised for its lengthy battery life, subscription-free app and integration with different Renpho merchandise. Monitoring accuracy and dimension choices, then again, obtained somewhat combined suggestions, whereas some customers additionally reported that the battery life is shorter than marketed.
One pleased consumer commented: “I’ve tried a number of sensible rings, […] however this one from Renpho is the very best! I paid about $187, there is no such thing as a month-to-month subscription price, it is vitally correct and it connects to the app on my telephone with NO ISSUES. I did not order the ring sizer. I simply ordered the identical dimension as all the different rings I beforehand bought and it was an ideal match. The completely neatest thing about it’s that the battery life lasts 9 – 10 days between recharging.”
Unfavourable opinions tended to say poor sleep high quality assessments and low coronary heart fee monitoring accuracy throughout intense exercises, in addition to temperamental app connectivity and points with Renpho’s customer support.
One disenchanted consumer stated: “Whereas it is comfy and I like the battery life, it is ineffective for monitoring exercise. It persistently offers me anyplace from about 35% to 50% too many steps. […] Then, the battery appears to be very contact and go, generally a day will run you 7-8% and another days it would run 15% no concept why. If the battery is under 30% train mode can’t be run in any respect. I perceive it’s a measure to guard the battery/machine, but it surely actually is not sensible to me to restrict performance at such a excessive threshold.”
Must you purchase the Renpho Lynx sensible ring?
The Renpho Lynx doesn’t dwell as much as its promise. It has some sturdy factors, reminiscent of its comparatively lengthy battery life, sturdy and light-weight construct, and a subscription-free app. Nonetheless, it comes with too many efficiency hiccups and design shortcomings to totally justify its value — except you actually need one thing robust and long-lasting. However in the event you prioritize monitoring accuracy and in-depth customized well being insights, the Renpho Lynx is probably not the most suitable choice.
✅ Purchase it if: You desire a utilitarian, sturdy sensible ring that gives primary health stats.
❌ Don’t purchase it if: You’re a health newbie on the lookout for your first sensible ring, or a critical exerciser on the lookout for advanced deep dives into their sleep patterns and post-exercise restoration.
If the Renpho Lynx sensible ring isn’t for you
If in case you have entry, take into account the Ultrahuman Ring AIR. Whereas it’s at present banned from being bought or imported into the US as a result of a patent infringement ruling by the U.S. Worldwide Commerce Fee (in favor of rival Oura), this neat sensible ring remains to be out there within the U.Okay., E.U. and Australia, second-hand or from third-party sellers. It’s subscription-free, trendy, ultra-comfortable to put on and jam-packed with helpful options.
In search of one thing extra premium (and don’t thoughts spending over $349)? Then you’ll be able to’t go fallacious with the Oura Ring Gen 4. It has been our “go-to” sensible ring for the previous yr or so, and for a superb purpose. It’s exceptionally correct and well-designed, and it regularly impresses us with its sturdy construct and genuinely helpful assessments of sleep and post-exercise restoration. The largest downfall? The Oura Ring Gen 4 requires a month-to-month subscription.
Renpho Lynx: How we examined
We spent two weeks testing the Renpho Lynx, assessing its design, battery life, options, ease of use, app connectivity and worth for cash. We wore this sensible ring through the day, whereas sleeping and when climbing, rowing indoors or performing low-intensity power exercises. We additionally checked on-line consumer opinions for any mentions of potential efficiency points.
Lastly, we assessed the monitoring accuracy of our Renpho Lynx by evaluating its steps, sleep and coronary heart fee measurements with the information we obtained utilizing two comparatively exact screenless health trackers: the Whoop MG band and the Oura Ring Gen 4 sensible ring.
