RingConn Gen 2 Air in Canada: the first three days
I chose the RingConn Gen 2 Air after sizing carefully; it detected sleep and short walks well, but step counts and exercise recognition need context.
Personal situation: I do not like wearing watches, but I rely heavily on rings. I wanted to track my heart rate, blood oxygen, sleep quality—without concerns about sleep apnea—and everyday activity.
After comparing several smart rings, I chose the RingConn Gen 2 Air because it met my needs and seemed comparatively cost-effective. I first bought a sizing kit on Amazon for 2.99. The kit contains plastic models from sizes 6 to 14; after wearing one as instructed for 24 hours, I could decide which size to buy. If anyone in Hamilton, wants to try the sizes, they can contact me.
The official recommendation is index finger first, then middle finger, then ring finger, because the data was collected using the index finger, where blood supply is clearer. In theory, the middle and ring fingers should not differ much. I prefer wearing rings on my middle finger because it is less likely to get knocked, and it does not interfere when I use my phone or write, so I prioritized the most comfortable finger.
Size 6 fits my middle finger just right normally. In the morning and when it is warm, my finger tends to swell, so it becomes slightly tight and leaves a faint mark. It does not slip off, but I need to use a little force to remove it. Size 7 was too large on my middle finger: when wet, it slipped off and rotated very easily. After considering the chatbot’s advice, I chose size 6, and it fit properly when the ring arrived.
I read in other posts that the ring may need about a week to become familiar with your habits, and that it may be somewhat inaccurate at first, so I am trying to keep it on the same finger for consistency. I have worn it for three days so far. Its step count is higher than my phone’s; I feel the phone underestimates steps while the ring overestimates them. I also do not know whether the heart-rate and blood-oxygen readings are accurate, so for now I am simply treating them as accurate. Sleep tracking is fairly good: it picked up the time I was awake using my phone in the middle of the night, although naps of 10 or 20 minutes are not always detected. It is reasonably sensitive to everyday exercise and detected a 10-minute walk. The drawback is that it can automatically recognize only a limited number of exercise types, so I need to confirm or add activities manually in the app.
I heard there is also AI to help analyze health data, but I may not have worn the ring long enough to unlock it yet. I will update this later.

- What to know
- RingConn’s US store lists the same Gen 2 Air generation, with a 2 mm profile, a wired charging dock and no listed subscription. The owner’s size-6 choice is personal; repeat the sizing trial on your intended finger.
Sizing matters more than the first fit
The owner’s choice between sizes 6 and 7 shows why a full-day sizing trial is useful: size 6 became tight with morning or heat-related swelling, while size 7 moved and could slip off when wet. RingConn’s guidance also calls for wearing the sizing ring for at least 24 hours, including overnight, before ordering.
RingConn recommends the index finger, while also supporting the middle or ring finger. The owner preferred the middle finger for comfort and chose size 6 after testing it; buyers who prioritize another finger should repeat the sizing process there rather than transfer the result from a different finger.
What the first three days can and cannot show
The owner reported a recorded nighttime awakening and a ten-minute walk, while ten- or twenty-minute naps were not always detected. These first three days did not establish longer-term accuracy, and the owner was explicitly unsure about heart-rate and blood-oxygen readings.
Step counts were higher than the owner’s phone readings, but the source does not identify which device was closer to reality. Treat the two totals as different estimates rather than using this account to correct either device’s step count.
The owner found that automatic exercise recognition covered few activity types and required confirmation or manual additions in the app. The photograph of the app shows a workout-selection screen with Walking selected, which supports the need to choose an activity but does not establish the full list of automatically recognized exercises.
Regional model facts to check before buying
The US Gen 2 Air listing supports iOS 17+ or Android 10+ and rates battery life for up to ten days, with approximately 90-minute charging. These are manufacturer specifications; the owner had worn the ring for only three days.
The listed ring does not include the Gen 2 sleep-apnea monitoring feature. That matters even though the owner specifically said sleep apnea was not a concern; buyers seeking that function should not assume it transfers from the broader Gen 2 range to the Gen 2 Air.
RingConn lists Partner AI as available by application through RingConn Lab, rather than automatically unlocking it after a fixed number of wearing days. The owner had not accessed the feature after three days, so this account cannot confirm eligibility, timing or the resulting analysis.
The official listing includes a wired charging dock and does not list a subscription. Because the source does not state the owner’s seller, warranty or local fulfillment terms, those practical conditions remain unknown and should be checked for the country where the ring will be purchased.
