RingConn Gen 2: six months of sleep tracking, but a poor workout fit

I used the RingConn Gen 2 for six months: sleep and basic heart-rate tracking worked well, but exercise caused slipping, inaccurate detection and no real-time heart rate.

I have given up on it. At first, it worked fairly well: sleep, heart-rate and step tracking were adequate. Once I started exercising, the ring's obvious drawbacks appeared.

  1. You have to wear it on your index finger for accurate recording. After I moved it to my middle or ring finger, it sometimes failed to recognize anything.
  2. The ring cannot rotate. The measurement area has to stay on the finger-pad side under the nail; it cannot measure from any other position.
  3. It is of very limited use for swimming. Water makes the ring slippery, so it naturally rotates and runs into the problem described in point 2. The same thing happens when washing my hands, so I have to adjust it promptly.
  4. Exercise detection is extremely inaccurate and cannot compare with a fitness band at all. I suspect this may be because blood flow in the fingertip is lower than in the wrist.
  5. Heart-rate readings are not real-time. For anyone who wants to see their heart rate during exercise, it is completely useless.
  6. Hand-cream users will have a particularly difficult time. Hand cream makes the ring slippery, causing it to rotate, and oil on the monitoring area makes readings inaccurate.
  7. It scratches easily, especially during weight training. I was too lazy to take it off because I still wanted to see my heart rate.

It does have advantages: it is genuinely lightweight, and I can barely feel it. After six months of use, seven days of battery life was no problem. It is only suitable for checking heart rate and sleep, with light exercise at most. If exercise matters to you, or you need to see your heart rate in real time, it is not suitable.

I bought it on JD.com at the time for less than RMB 1,300. It has gone up in price now, so you might want to wait for a better opportunity.

Before You Buy

Models in your region

The owner used RingConn Gen 2 for six months. RingConn sells that same generation in its US store, with a charging case and no subscription. The owner's concerns center on fit during exercise and viewing heart rate during a workout.

What to know
RingConn recommends the index finger but also supports the middle and ring fingers. This owner found recognition less reliable away from the index finger; use the sizing kit and check fit on the finger you intend to wear it on.

Fit and sensor position matter during daily wear

The owner found that reliable recognition depended on wearing the ring on her index finger and keeping it from rotating. Hand washing and swimming made that difficult because water loosened the fit, while hand cream added slipperiness and oil over the monitoring area. These are personal observations from her six-month use, not a controlled accuracy test.

For US buyers, RingConn recommends trying the sizing ring for at least 24 hours, including overnight, and says the sensor should face the palm. The company permits the middle and ring fingers, but a secure fit and temperature-related swelling still matter. The owner’s difficulty on those fingers means buyers should confirm their own fit before relying on exercise readings.

Exercise tracking is the central trade-off

The owner considered exercise detection extremely inaccurate compared with a fitness band and said the ring did not provide real-time heart-rate information for workouts. Her explanation about fingertip blood flow is a personal suspicion, not a verified diagnosis, so it should not be treated as the manufacturer’s reason for the result.

That makes the Gen 2 a poor match for buyers whose main purpose is monitoring heart rate during training. The account does not provide measured error rates, a named workout mode, or a controlled comparison with a specific band, so it cannot establish how the ring performs across all exercises or users.

Swimming is especially problematic in this account because water caused the ring to rotate, changing the sensor position. The owner therefore found swimming of little practical use, but the report does not separate fit failure from the ring’s underlying swim-recording capability.

Battery and comfort support lighter use

The owner reported seven days of battery life after six months and described the ring as so light that she could barely feel it. The US product page rates Gen 2 for 10–12 days and lists a charging case; the difference may reflect usage, settings or battery condition, but this account does not identify which factor caused her result.

For sleep and basic daily tracking, the owner said recording was adequate and described light exercise as acceptable. That conclusion belongs to her unit and routine; it does not confirm equivalent results for every size, fit or software region.

Materials and ownership details to consider

The owner found the ring easy to scratch, particularly during weight training, and chose not to remove it because she wanted heart-rate readings. Buyers who lift weights may therefore need to choose between keeping it on for continuity and removing it to protect the finish; the account does not identify the exact surface treatment or quantify the scratches.

RingConn lists a 2 mm titanium-alloy shell, 2–3 g weight depending on size, a charging case and no subscription for Gen 2 in the US. Phone support is iOS 17+ or Android 10+; check local app access and seller support before importing.
