I would have bought a wearable health tracker much sooner if they weren’t all so ugly.

I don’t want a glowing screen on my wrist, and the Whoop woven bracelet looks like something I would have made at summer camp. But in recent months, both RingConn and Oura have released slimmer hardware that actually matches the jewelry, so you don’t have to shout to the world that you’re currently monitoring your blood oxygen level.

So, against my better judgment (and the knowledge that I’m giving a tech company my health data for no reason), I bought my first daily wearable health tracker: the RingConn 3. About ten days later, I was relieved to discover that it was still within the two-week return period and dropped it off at the post office.

Between RingConn 3 and Oura Ring 5, I went with RingConn simply because it’s less expensive, starting at $349 compared to Oura’s $399 starting price. That’s not a huge difference, but Oura also requires users to pay a $6 monthly subscription to use a device they’ve already paid for, which is the kind of blatant money-grabbing tactic I think a CFO comes up with while twirling his mustache and laughing. I don’t want to appease the man with the mustache.

At first glance, the rose gold RingConn 3 exceeded my expectations. It’s really pretty! Matching the Oura Ring 5, at 2.3mm thick, it’s still a little bulkier than the standard ring, but still comfortable to wear.

In reality, it passes as a normal piece of jewelry, especially if you combine it with another stackable ring. When you order the ring, they first send you a sizing kit, so it’s worth taking the extra step. I was tempted to just order my normal ring size, but found that I actually had to choose a larger size for a comfortable fit.

The construction of the RingConn 3 feels solid. While some people online say their rings quickly showed scratches, I found that the brushed metal version felt sturdier. I didn’t have the ring long enough to confirm its claims that its battery can last 14 days on a charge, but I didn’t have any issues with the battery.

While the ring is waterproof, you can even wear it swimming! – I decided to just leave it in its charging case every time I showered.

Aesthetics aside, the RingConn 3’s screenless form factor appealed to me because it’s something I can use passively, check once a day at most, and reflect on the data later. I’m not the only one with those preferences: American spending on fitness trackers grew 88% year over year, largely due to screenless wearables like the Oura ring and the Whoop bracelet, according to market research firm Circana.

But in terms of health tracking, RingConn 3 was not as useful as I expected.

For the first few days, the data the ring recorded was like a shiny new toy. I enjoyed checking the app to see if my heart rate or stress levels changed as the day progressed. It seemed like my stress levels stayed stable, but increased when I did laundry (exactly, to be honest).

I found the sleep insights interesting, but they mostly confirmed what I already knew without spending $349: I sleep poorly when I drink and better when I keep a consistent bedtime.

Still, I was disappointed to find that RingConn 3 requires a lot of manual intervention. It only detects workouts if you’re physically moving in space, so if you’re at the gym or doing Pilates, the ring won’t automatically realize you’re exercising. At the same time, you’ll mark any two-minute walk around your apartment building as a short workout. (I promise, my heart rate is not significantly affected by receiving the mail.)

I thought RingConn would have been worth it if only for its headache detection feature, which supposedly warns you of impending headaches by monitoring your heart rate variability. I suffer from unpredictable migraines, so if they could notify me to take my migraine medication proactively, the ring would have been revolutionary for me. It’s surely worth the $349.

But about a week into owning RingConn, I suffered the worst migraine attack of my life. It lasted an entire weekend and the pain was so intense that I sold my tickets to see one of my favorite bands.

Meanwhile, the ring was telling me I was in “better shape.” If the headache detection feature wasn’t going to work for me, I just didn’t see myself wanting to use RingConn every day. I decided to return it while I could still get my money back.
